I am at a process of migration SBS 2008 with Exchange 2007 SP3 to Server 2012 R2 with Exchange 2013. At later stage I will remove the SBS and will upgrade the Exchange server to 2016.

*The exchange server is running on Server 2012 R2, and there is a second domain controller - also Server 2012 R2.

However at the moment, I have the following issue:

 - Outlook 2010 started to prompt for password after the mailbox is migrated to the new exchange server (using cache mode) - this was fixed by changing the security settings for the account to use Password authentication (NTLM).
- If I upgrade to Office 2016 the Outlook prompts again for password in cache mode - in online mode everything is working fine.

All workstations are running Windows 10 Pro

What I tried so far:

1. Clearing all credentials in credentials manager.
2. Recreating Outlook profiles.
3. Clearing all credentials in credentials manager, rebooting the computer and recreating Outlook profile.
4. Adding registry fix to disable the auto discovery for Office 365.

Thank you for all you replies in advance :)

I need to send an email to 80 customers.  I put all 80 email addresses in the "Bcc" field in my Outlook 2010, just as I've done in the past with no problem.  But this time when I 'Send', it kicks out all 80 addresses, saying "554 mail server permanently rejected message (#5.3.0)".  I'm hoping someone here can give me some direction so I don't waste a lot of time searching for a solution in the wrong place.

Could this be caused by my email provider, which is Network Solutions?  Or could it be caused by a setting in Outlook, or something about Windows 10 Pro?  I can't imagine it is a problem at the customer level, since all 80 are kicking out immediately.  

I did send two of them out individually, and that worked fine.  I don't want to test it by putting all 80 email addresses in the normal "To" field, because that's the whole reason I'm trying to use the "Bcc" field.
Need help to design the...ULTIMATE OUTLOOK QUICKSTEP: Waiting For Based on New Messages

Fans of GTD & David Allen's Outlook Plugin - sadly EOL - will appreciate this one.

Is there any way to design an Outlook Quick Step for NEW messages which...

1.) Sends the new message
2.) Stores the sent new message in a directory OTHER than Sent Messages (For example @Waiting For)
3.) Categorizes the message with a specific Category tag.

Seems like it nearly can be done via Macros but...not elegantly, creating a Task from the message rather than using the message itself: https://www.slipstick.com/developer/gtd-create-task-sent-message/

Can this be done acting on the message and via Outlook Quick Steps ?

How does it look to you?


On a new 2016 RDS deployment, I have an issue where any customization made by a user is lost when they sign off.

user pins outlook to taskbar, it's gone the next time they log in
all plugins to google are gone
desktop icons 'referesh' as if windows is just seeing everything for the first time

We are using User Profile Disks.

I originally had selected 'store all user settings and data on the user profile disk'
I've since tried moving to 'store only the following folders' and un-checking 'roaming user profile data' and 'user registry data'

Nothing seems to work and I can't figure out why this data is not being saved.
Exchange 2010 spam filter issue with default smtp domain(abc.com), I have 1 user complaining that emails from newsletter@abc.com go to her Outlook spam/junk folder every time, can someone try to help me with this issue? This particular email is composed in another online service that has authority to relay messages through abc.com, how can I see if Exchange is moving the messages to the spam folder or if it is Outlook?
Hello all,
I have a client that is using IMAP for all of their emails.  We are changing providers for them from Blue Host to something else.
Obviously they want to keep all previous emails which they will not have with the new provider.  They are using Outlook 2013 and Outlook 2016 on their computers.
What is the best way to keep these emails?  Is it to copy these OST files to PST files or is there another way?

I have a ticket on Microsoft about my Symantec SMG (anti-spam) is receiving the  "451 4.7.500 server busy" from mail.protection.outlook.com (Hybrid exchange 2010 / Office365 -and Postfix for some days) when I try to send a email to @hotmail.com (my send connector send to SMG. It has to be this way, and it was working until two days ago).

This question is the same point:

The Accepted Solution is:
"We were being throttled by Outlook.com addresses.  Exchange was trying to send the health check emails outside.  Fixed that and now everything goes through fine."

what does "Exchange was trying to send the health check emails outside.  Fixed that and now everything goes through fine" mean?
I am trying to populate a TreeView control in a VBA form with Outlook 2010 Task folders. But I am having trouble with picking-up child nodes, only the top-level folders (like FolderA, FolderB and FolderC) are listed in the TreeView control.

The Task folder structure is set up as:

|------ FolderA1
|------ folderA2

The TreeView control is only listing:


This is the code I am using, but how do I list all sub-folders (child nodes) in the TreeView control:

If vRecipient.resolve Then
  Set vFolder = vNamespace.GetSharedDefaultFolder(vRecipient, olFolderTasks)
End If

If Not (vFolder Is Nothing) Then
    For i = 1 To vFolder.Folders.Count
        TreeViewTaskFolders.Nodes.Add Text:=vFolder.Folders(i).Name

    Set objTask = vFolder.Items.Add(olTaskItem)
    MsgBox "problem with connecting to network."
End If
What is the correct process to use to set up an Outlook 2016 Gmail account to save emails to a PST file instead of an OST file?
Hi - For some reason, a clients outlook add-ins are not loading at all when Outlook starts up. As you know, usually you’ll see them load one by one at the bottom of the outlook box once you launch it. But now, it seems to skip it and go right into Outlook. If I go into the options/add-ins I can see them all there and checked. Anyone have any idea what would cause this or what I can do to fix it?

I run an Office 365 Business account for my company.   We've just recently started enabling Multi-factor authentication for my users.

I've run into a problem where every time I enable it, then have them log into office.com to set up their app password it then doesn't synch up with outlook 2016.

To be more specific.  I enable it for them, then have them log into office.com and then click the "Set it up" link where they receive the verification text on their cell phone.
Then I have them open outlook desktop app (outlook 2016) and we would expect it to prompt for a new app password.  It's not.  If I leave it alone, about 1 to 2 hours later it stops working and will not open at all claiming the set of folders is unavailable.

If I remove the profile and have it restart, it accepts the app password but then still says the set of folders is unavailable.

The only way I've found so far to fix this is to go back into their account, disable multi-factor.  Then re-enable it and have them walk through the setup again.  This seems to do the trick.

Is there a time period I should be waiting before trying to access it?  Or is there something else going on I'm not aware of?

any help would be great.
Hello All,

We would like to use Exchange resources (Room Mailbox). We integrated Calendar room with SharePoint to use outlook schedule assistance features for booking rooms. We install SMTP/configured service on SharePoint server and create  send connector. Now SharePoint is acting like a child domain and the email format on the SharePoint SMTP is xxxx@sharepoint.Mydomain.com. In this case, while selecting room(resource in schedule assistance) is not sending email to xxx@sharepoint.mydomain.com. On the word not calendar is not auto updating content on SharePoint . So how I can forward resource mailbox to a SharePoint contact? I can forward individual mailbox but don’t know about Resource mailbox.

Thank you
Has anyone encountered an issue with Outlook 2016 on a Mac running High Sierra, where certain email are not automatically downloading images? I've updated the IOS to High Sierra, attempted to update the Office product but no updates are available. I've already checked, Preferences -> Reading -> Security, and checked "in all messages" for automatic download pictures from the Internet, and some emails show images while others do not.

Is there anybody who could help us to solve this issue. What we want to do is to select 2 or more attachments of an e-mail in Outlook 365 and drag and drop these files on a listbox. The files should be saved in a folder as file and the name of the file added to the listbox.

In the DrapDrop event of listbox, we handle the e.Data if "FileGroupDescriptor" is a member of the data (GetDataPresent).
It is possible to extract the number of files that are dropped and we can extract theses names of the data. See the example below ("Get names of files that are dropped").
This works fine. But now we will get the data of each separate file from the e.data stream. The first one is not a problem, see 'Get memorystream of data of file' in the sample code below. But how can we get a memorystream of the second, third etc files of the drop action?
Any help will be appreciated

    If e.Data.GetDataPresent("FileGroupDescriptor") Then

      ' Get names of files that are dropped
        Dim theStream As Stream = CType(e.Data.GetData("FileGroupDescriptor"), Stream)
        Dim fileGroupDescriptor(theStream.Length) As Byte
        theStream.Read(fileGroupDescriptor, 0, theStream.Length)
        Dim liNrFiles As Integer = fileGroupDescriptor(0)
        Dim fileName(liNrFiles) As System.Text.StringBuilder
            For liY = 1 To liNrFiles
                fileName(liY) = New System.Text.StringBuilder("")
                Dim i As Integer = 76 + ((liY - 1) * 332)
I have a rich text field which is having content like Images and sections and some other content like paragraphs which is being called to mail body to send mail when clicking on the button.

Is it possible to convert rich text body field to text field to call it email body field?

is there anyone can help me on this.

actually, we do have a third party tool which helps to convert emails from notes to outlook. when email body is having rich text content it will stop email in notes side and compose a new email in outlook and it sends to the user.

I am trying to find a solution for the following.

We have got recurring agenda items in our Outlook calendar, shared with a couple of staff members. This worked perfect for us when we have had Exchange running on site.
However, we recently moved to Exchange Online and experience a delay when an agenda item is completed. (+/- 1-2 minutes before it is removed on another client pc)
This results in another member of staff doing the same job as the one who completed it a few minutes ago.
When we had Exchange running on site it was deleted in a few seconds and we did not have this problem.

Our office staff is increasing so I am looking for a long term solution. A cloud option or an application to run on site.

Can someone recommend me such tool which includes:
*Create recurring tasks
*Assign to a member of staff
*Getting a pop-up when an event occurs

It doesn't need to have the extra bits like time-tracking or a process bar of a project.
Just a simple recurring task tool, without delays.

Thank you.
Exchange not syncing to outlook client.  

Exchange is not syncing consistently to the company CEOs (!!!) laptop outlook 2016 standard client.  She will get all email on her OWA, phone, and if she logs on to another laptop it works as well.

I have:

1) repaired office
2) deleted/recreated profile
3) checked rules (zero rules) (I even checked exchange server for mailbox rules and found zero rules)

Next off I was planning to uninstall office 2016 standard, and install office 365
Any further troubleshooting suggestions?
I would like some direction on how to create a private folder in all versions of outlook so if I give someone access to my inbox they can see what is in the private folder under my inbox.
We are currently running into a strange issue with Exchange 2013 and Outlook 2013. I am not sure if it is a limitation of Exchange or Outlook.

We have a system that is set up with Outlook 2013 so that all user mailboxes can be accessed by an administrator account. On the Exchange 2013 server we have been using "Add-MailboxPermission -Identity USERNAME -User adminaccount -AccessRights FullAccess" to enable this access.

In the past couple months we have run into an issue where two of the mailboxes can not be accessed. The message "The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance." If I run "Remove-MailboxPermission -Identity USERNAME -User adminaccount -AccessRights FullAccess" and then run  "Add-MailboxPermission -Identity USERNAME -User adminaccount -AccessRights FullAccess" I am able to access those two mailboxes, but two other mailboxes break. When I repeat the same steps with those broken mailboxes, another two break.

Any ideas?

I am having issues with outlook 2016 running slow and freezing. It is connected to office 365 ie Microsoft hosts the email.

I am looking for any trouble shooting steps and solutions.

Sorry I don’t have any more specific information.


We have a really strange problem affecting us at the moment.
A bit of background of our setup. We have Office 365 and currently using Office 2013. Office 365 integrates with Mimecast and Exclaimer cloud (email signature software).

Inbound emails threads are having the body of the email pushed to the bottom of the email. The top of the email has all the standard information (from, to etc) but the user has to scroll to the bottom to see the latest content of the email. Under the from/to information there is a carriage return but no body.
This only appears to be affecting certain domains at the moment (we have around 3/4 users reporting it from 3/4 different domains).
If we recover the email from mimecast (email filtering) the email shows in the correct format with the body in the normal place.

We've had it logged and got nowhere with Microsoft support and Exclaimer Cloud.
Has anyone else see this before?
Hello Experts,

I did a Windows update and a McAfee update, and since then have two problems. The first is most important: my RDP connection for my job disconnects and then reconnects every 10 seconds to  two minutes. I looked at the Microsoft Windows Terminal Services logs and see all the disconnection events, but there are multiple errors codes/descriptions that seem unrelated and I stopped analyzing those logs hoping you will have guidance for me.

The second problem is the hyperlinks in my Microsoft Outlook email no longer work and display a message that says, 'This operation has been cancelled due to restrictions in effect on this computer...' I attempted to reset my internet options, but that did not resolve the issue. I am reluctant to run the fix tool that is available on the Microsoft support page because Windows 8.1 is not listed in the OS list.  Do you have any advice for me?
Respectfully, Chop
I have a user who has two Office 365 domain names. They want to Copy all emails and sub folders from one Office 365 email domain account to another. What the fastest way to do so other than dragging one folders at a time between accounts on Outlook?
I need to find a way to disable the "Collapse Ribbon" button on Outlook 2016.  We recently upgraded one of our executives and the ribbon keeps collapsing.
