We are migrating from Exchange 2010 to Exchange 2016.  Everything has gone great thus far.  The last thing to move before we uninstall Exchange 2010 is public folders.  We would like to convert them to room mailboxes.  The public folders have only calendars in them for scheduling the conference rooms they represent.  There are only six public folders.  

What would be the easiest way to move the six public folders in Exchange 2010 to room mailboxes in Exchange 2016?  Remember, the public folders have only calendars in them.


I am trying to export users from about 300 groups to CSV. What is the best way and command to do this? DO I need to create a file before hand for the command to recognize the group names?

Thanks in advance and your help & suggestion must be appreciated.

Thanks & Regards,

I have an intermittent updating problem with a mailitem in the explorer mode on a public folder of an outlook exchange server 2010. The subject (or perhaps any part) of a mailitem does not seem to update itself at times.

Specifically, the subject of the mailitem shown in the explorer mode is dissimilar to that shown in the inspector mode. In other words, the explorer mode needs updating or synchronization.

Hitting F9 (send/receive) to update the public folder does not seem to help.

I would like to know if this anomaly can be detected (and perhaps perform manual updates/synchronization) using an outlook macro.

Thank you.
I'm new to email servicing.  I had an email in our system automatically start a move request over to our new office 365.  So after getting the account over to office 365 it is showing that it didn't have an email come in since August 1st.  I'm trying to figure out how I could retrieve these emails(if they are even there) from our mailbox servers.  We are running Exchange 2010 and have 4 mailbox servers.  Do I look in the mailbox servers and how do I see what is in there?

I've got an exchange 2010 server, that the one and only main edb (500gb) crashed. I then moved all my mail to 4 x roughly 100gb edb's

The 500Gb edb was on a drive for the exchange, at the moment i have the edb's spread over two drives.
I have deleted the old 500gb edb.
I would like to move these 4 edb's onto one drive again.

My issue, is that, when it was one edb, it was 500gb, now i have 4. it's around 675gb. this is the actual edb, and does not include the e00.....files

Mailbox A - 100gb
Mailbox B - 118gb
Mailbox C - 318Gb
Mailbox F - 140gb
Total - 676gb

I cannot move mailbox c back to the exchange drive we have, as I don't have enough space. as we used to have 150gb spare and now find myself 25gb short.

I've run a check on whitespace and can confirm it mb's for 3 of the edb's and 8gb for mailbox c. So it's not that.

I'm unsure how this has happened and how to shrink it all.

All this work has been done in the last week. And can't be down to natural growth.
In the query below, i am try to import AD dist groups(both distribution and security groups)  from a CSV, and would like to return the user name and email address and indicate whether the groups is regular distribution or a security group.  Is it possible to get these results?

Get-ADGroupMember "dist.grp" | select samaccountname | %{Get-ADUser $_.samaccountname -Properties mail} | %{write-output "$($_.samaccountname) `t`t  $($_.mail)"}

Our Microsoft Exchange Server 2010 is for some reason using the highest number priority MX record before it uses the lowest number.  It continues to have problems sending out emails and the logs are showing its using the highest numbered record.  The problem with several of the domains we send email to is their highest number priority records

My interim fix has been entering a separate send connector for each of the domains have the problem.  I specify the send connector just for that email domain, and instead of using DNS lookup I enter the FQDN of the lowest priority number MX record into the Smart Host area.

Have had to do this for 3 domains now that have high priority number MX records pointing to mail servers that are not responsive.

Hi All

Anyone got any idea how I can set my default email policy in exchange online?  At the moment whenever i create an object it uses my emailaddress@mydomain.onmicrosoft.com.  I would like to set the defaults up as *@mydomain.com.


While trying to setup a protocol for Exchange to Exchange migration when moving roles from Physical to Virtual, I came across some issues.  Any information that can be provided will be appreciated.

MAIL-01 (Physical)
MAIL-02 (Virtual)
CLIENT01 (Client machine)
User01  (Test user)

Phase 1:  MAIL-01 is running well in AD and clients are connecting correctly via Outlook and OWA

Phase 2:  A VM was put in place to migrate the physical server.  Both Exchange were co-existing well.  Clients connect well to MAIL-01.

Phase 3: All the mailboxes were migrated to the database from MAIL-02 in preparation to move completely to the Virtual Environment

Phase 4: Pilot testing.  Some users were able to connect to MAIL-02, but others could only connect to MAIL-01

Steps performed after Phase 3 and before Phase 4.

DNS record updated to add the autodiscovery pointing to MAIL-02
Tested access to MAIL-02 via OWA when MAIL-02 was temporary offline  (All worked well).
Exported the certificate from MAIL-01 and imported into MAIL-02.

Any missing step you can suggest?

Curent status:  Both servers are on:  Some users seem to connec to MAIL-01 and others to MAIL-02
I would like to get some information from outlook. Basically, get the number of emails received every month, but not just for the current view (this is what my code does right now, fut for all subfolders, up to 2 depth). I have tried with this:

'The following codes are working to count by day
Sub CountReceivedEmailsbyDay()
    Dim objItems As Outlook.Items
    Dim objItem As Object
    Dim objMail As Outlook.MailItem
    Dim strMonth As String
    Dim dReceivedTime As Date
    Dim strReceivedDate As String
    Dim i, n As Long
    Dim strMsg As String
    Dim nPrompt As Integer
    Set objItems = Outlook.Application.ActiveExplorer.CurrentFolder.Items
    objItems.SetColumns ("ReceivedTime")
    strMonth = InputBox(“Enter the specific month.(Format: yyyy-mm)”, “Specify Month”)
    If strMonth <> "" Then
       n = 0
       For i = 1 To objItems.Count
           If objItems.Item(i).Class = olMail Then
              Set objMail = objItems.Item(i)
              dReceivedTime = objMail.ReceivedTime
              strReceivedDate = Year(dReceivedTime) & “-” & Month(dReceivedTime)
              If strReceivedDate = strMonth Then
                 n = n + 1
              End If
           End If
       Next i
       strMsg = "You have received " & n & " emails on " & strMonth & "."
       nPrompt = MsgBox(strMsg, vbExclamation, "Count Received Emails")
       nPrompt = MsgBox("Please input the specific month!", vbExclamation)
whats the syntax to specify 2 or more servers in the get-transportservice cmdlet?

Hello peeps

I have a user who is unable to print certain emails from Outlook.  He keeps getting the message:-

Outlook 2013 will not print certain emails. Error message: "There is a problem with the selected printer. You might need to reinstall this printer"

I logged in as myself on the users machine (haven't logged in before so was a new profile)


1.  Removed both old printers.  Installed the drivers for both printers on machine from Manufacturers website and added printers again - Unsuccessful

2.  Setup users outlook profile on my login and tried to print the same email  - unsuccessful.  Same problem with same error message.

3.  Also forwarded the same email to my account (i'm using Outlook 2007, don't ask why lol).  Tried to print. - Successful

Can anyone help?
Exchange Server 2013

Using Exchange EMC

The mobile devices for a particular user are in a hung state with the message saying "Gathering Client Information".
When I click the delete icon it says "Pending Deletion"

Then as I click save I get a message saying mobile device not found. I get the same message when I try to edit the device.


I'm in process to migrate my users mailboxes from Exchange 2007 to O365.

I set a Send Connector rule to send all emails for migrated recipients to O365 MX server. Now  I got a msg from O365 like:

mail.protection.outlook.com #550 5.7.1 Service unavailable, Client host [x.x.x.x] blocked using Spamhaus. To request removal from this list see http://www.spamhaus.org/lookup.lasso

Why my Hub Transport is considered as spam? How can I whitelist my server in O365?

I am aware that it is not a technical question and I really appreciate any help.
I am looking for a book or training video for full hybrid implementation of Exchange 2013 and Office 365 with Azure AD Connect.
I have a good understanding of Exchange and Office 365 and looking for a in dept training material.
I tried Udemy but it is not up to date.
our company had one ex employee keep sending the email (with his own private Hotmail email ) to other current worker, how can I redirect all his email to one user I set up to receive all this ex employee's email and follow up. and the original recipient won't receive any email from him.

btw--we had exchange 2007 .

Using Outlook Web Access (OWA) to an Exchange 2010 server with Firefox. In the compose new message window I am unable to attach a file. I click the paperclip icon in that window's toolbar and get no response. The other buttons on the toolbar are also unresponsive. It is not a problem with other browsers and it also works in Firefox with the "light" version of OWA. I tried removing any popup restrictions but it didn't help. Seems to have started recently, presumably after a Firefox update. I have also tried updating the Exchange server without effect.

What could be the problem? Where should I focus my investigations?
Hello fellow Experts Exchange members:

I have a confounding problem with one user who has Office Home & Business 2016 installed on a domain-joined laptop that is often used to connect from outside the office using VPN.

(This is not occurring with any other user.)

I had to recreate the user's Outlook profile this morning due to an unrelated issue.  When attempting to reconnect the user's Outlook to the on-premise Exchange 2013 server, the autoconfiguration process appeared to behave normally.

However, upon opening Outlook, the user's e-mail address was incorrect.  In fact, the e-mail address was not even for the same e-mail domain - e.g. @Company.com.

Somehow, Outlook on the user's laptop had configured itself with an "outlook_[long series of numbers and letters]@outlook.com" e-mail address.

The user's previous e-mails were not in the Inbox or Sent Items folders, and none of the user's previously-created subfolders appeared.  Also, there were no contacts or calendar items.

When I tried to send a message, the message sent successfully, but the resulting e-mail appeared with the outlook_@outlook.com e-mail address instead of the correct user@company.com e-mail address.

I tried logging in at Outlook.com with the user's user@company.com e-mail address and password was able to log in.

However, I also tried logging in at the Outlook Web Access (OWA) page for the on-premise Exchange 2013 server and was also able to log in using the user's user@company.com …

I have recently deployed a new Exchange 2016 server in our current SBS 2011 (Server 2008 R2) environment.  The SBS 2011 server is the current domain controller.  I have noticed that ever since moving the Arbitration system mailboxes from the old Exchange 2010 server to the new Exchange 2016 server I am now receiving a Directory-Services-SAM Event ID 16969 error every 15 minutes which states:

"XXX remote calls to the SAM database have been denied in the past 900 seconds throttling window."

  I am not sure if moving the mailboxes is what caused it, but I was not receiving this error before.  After checking the domain controller I did not see any policy that specifically defines this security policy so I am not entirely sure what is causing this to fail since in the local security policy on the Exchange 2016 server has the local Administrators defined to allow access.  Any idea as to what would be causing this?  

Thank you

We have an environment running exchange 2010 with office 2010 sp2. I have two users that have full access delegation rights to a shared mailbox. Whenever they are sent a meeting request the request also appears in the shared mailbox. Can anyone suggest what is causing this and how to prevent it from happening.
