i finished installing the exchange 2013 CU 21 and unable to launch the ecp or OWA, if anyone can please help it would be great.

Error Message :- Outlook
Bad Request :(
The request sent by your browser was not valid.
An outlook mailitem on an exchange server, shared by two users is prone to a conflict, especially when one of the users tries to make modifications to it. For example, if the two users each have the same mailitem opened at the same time(2 instances), and one of the users tries to modify (and save) it, the outlook explorer will show the mailitem in a state of conflict.  The state of the mailitem can be detected via Mailitem.isConflict property.

However, my problem is not detecting this state of conflict, but preventing it from happening in the first place.

How do I detect if more than one instance of the same mailitem is opened on a network share at the same time (by different users), thereby programmatically blocking any of these users from saving modifications to the mailitem?

Dim myInspectors As Outlook.Inspectors 
Set myInspectors = Application.Inspectors 
if myInspectors.Count > 1 then
   ' do not save mailitem
end if

Open in new window

Any ideas are welcome.
Kindly provide VBA code if possible.

Thank you.

I am attempting to resolve an Exchange 2013 ActiveSync related issue using Microsoft Remote Connectivity Analyzer (EXCRA).  The test works up to the point where the tool tries to send the OPTIONS command to the server.  I receive the error message "Testing of the OPTIONS command failed. For more information, see Additional Details."  403 error in the additional details, attached.

This error has been reported several times over the past years and I've tried all the solutions that I believe apply to me, to no avail.  I'll try to answer as many of the common questions up front.

I can't seem to get any exchange mail on my iphone X.  We're running on premises Exchange 2010.  When I add the account on my iphone, I choose exchange and enter in all the details.  It passes, I get all "checkmarks", but no mail will load.  Folders won't even load.   Any ideas?  Btw, this very phone had email working just yesterday, but I decided to reset to factory and start from scratch.
Good Morning Experts,

Mary Doe has publishing editor permissions to John Doe’s calendar.  She recently cancelled an appointment she created on his behalf, however, we have been unsuccessful in deleting it from her calendar.

The meeting attendees are also receiving several cancellation notices.  These seem to be sent sporadically, as the most recent was sent out yesterday, and Mary has not been sending them out.  

Last week, I was remoted into Mary’s computer to try and resolve the issues with this appointment.

I did a repair on her Outlook profile, removed her Outlook profile, tried to delete the appointment via webmail, and was not successful.

I also RDP into John’s computer this morning and did a repair on his profile, removed his profile, and also checked on Mary’s permissions to his calendar.

Everything seemed to be in order on his end.  Could your please look into this further, as I have run out of troubleshooting options?

Please, advise how to stop getting this cancellation meeting notices on user's mailboxes and explain what would happen if there are several scenarios

Provide step by step instructions with screenshots
Hi guys,

I have recently a migrated domain to office365 .
Got one pop3 email account which needs to be migrated to office365.
If it’s windows- I can copy the pst from old pop3 profile and import to new office365 profile.
But I got Mac computer- how do I do it? As I am not aware of Mac profile
I’m not sure if it is working as intented or not.
So, doing crosfortest move, mailbox becomes linked to user in user forest. Outlook redirects fine to new exchange but iphone doesnt, if i manually change server name under account it works as expected so the question is , should iphone automaticlly autodiscover new server in already existing exchabge account ? Autodiscover also works fine if i recreate account...
Recently upgraded Exchange from 2013 to 2016. Everything looks good and have been running for over a month without issues. Currently 2013 is in co-existence as its also the file-server role and although I've dismounted the EDB from old 2013 server, I havent uninstalled Exchange from it.

I wanted to do some delivery reports under Mailflow, and got this error - Value specified for a parameter of type Microsoft.Exchange.Diagnostics.MessageTrackingEvent is invalid: SENDEXTERNAL.

Any ideas?

Any help is appreciated, thanks!
Hi Team,
I have Exchange  2013 installed in my Environment.

One of the user is not able to be added in outlook . I am getting the following error.

The action cannot be completed. The name cannot be matched to a name in address list.

Please help me sort this.

This user can connect to OWA.
My client's Iphone won't sync to Outlook whenever I add a contact to the IPhone.  It does sync when I add a contact to Outlook.  It also syncs whenever I edit a contact on the IPhone or in Outlook.  So, the only problem we're having is when we add a contact to the IPhone, it won't sync to Outlook.  We're using Outlook 2016 with Exchange 2010.  

It used to work, but now doesn't.  The only change he has made is he updated the iOS to 12.1.  Please let me know if you have any ideas on this.  I've researched this thoroughly, but can't find any solutions.  Thanks, Barbara
I'm trying to create a transport rule in Exchange 2013 to achieve the following:
If someone sends an email with x@mydomain.ca in BCC, I want to add x@mydomain.ca in the To field.

We need to do this because the system we use to process these emails cannot process emails when they come in via BCC.
So we need to find a way to modify the message or forward a copy with x@mydomain.ca in the To field insead of BCC.

In the transport rules, there are options for "To/CC box contains this person" but nothing for BCC.

Does anyone have experience with this kind of requirement?

Thanks in advance!
Hi, it has been a few years since I have dealt directly with IT ADMIN...did it for 10+ years but been away CEO'ing for 6 years and now with a new startup and a non-profit we are working with, they have a scenario I need to fix. So...they have an Office 365 Non Profit Premium Account with 25 users, but their email was for some reason hosted with Rackspace Online Exchange and Rackspace is a pain bc they block any migration solutions and force you to create accounts on Outlook or similar, IMAP acc download all email etc and then export pst file then import/upload to 365...so working through that now. But, i also have (2) servers with 2012 r2 standard and a Sonicwall (i prefer pfsense, but its what they have) one sever is the controller and AD, but for some reason, we have some users on one server and others on the other. do not know why. besides AD the first server is just running a print and file server and the second is just doing backup for a few files. i have no idea why it was setup this way.

regardless...my thought is a hybrid setup. I would like bc we via Techsoup.org qualify for realllllly cheap licenses for windows sever 2016 standard and CAL's plus upgrading all win7 machines to 10 pro, that I would like to upgrade both servers to 2016 standard, add exchange 2016 (? or 2013...as Im not sure about how the licenseing works there)  and connect via Azure online free account to Office 365 as outlined in the hybrid setup.

and setup a VM on the second server for our new…
Issues installing Microsoft Exchange Server 2016
A MAC user reported"The mailbox database is temporarily unavailable. underlying MAPI stream threw an exception. Mail could not be sent. The message has been moved to your Drafts folder."
Hello All,

I got the below script in Expert Exchange. This script checks for newly created AD account and enable the mailbox.

I wanted to include a condition like if the ad account belongs to separate OU, it should not enable the mailbox.

Can anyone please help me to achieve the above condition?

Import-Module ActiveDirectory

$lastday = ((Get-Date).AddDays(-1))
Get-ADUser -filter {(whencreated -ge $lastday)} -properties DisplayName,SamAccountName,legacyExchangeDN | Where{$_.legacyExchangeDN -eq $null} | Select DisplayName,SamAccountName,legacyExchangeDN | Sort DisplayName | Export-csv 'c:\temp\Acctswnomailbox.csv' -notypeinformation
Import-csv 'c:\temp\Acctswnomailbox.csv' | %{Enable-Mailbox $_.SamaccountName -database "DB02" -erroraction SilentlyContinue -verbose}

How do I share out a users calendar to multiple user calendars on the Exchange server?
I have done it for users in Outlook but there must be  a easier way on the Exchange server Ver 2010
I have a csv with 1000+ distribution groups, formatted like so:


I need help with creating a quick powershell script to remove all members from each distribution group via powershell.  Would appreciate any help in this task.
We have a Distribution group in Office 365 that only allow internal senders. When an internal user sends an email as a shared mailbox to the distribution group, it fails to distribute the email.
Message trace error: Reason: [{LED=550 5.7.133 RESOLVER.RST.SenderNotAuthenticatedForGroup; authentication required; Delivery restriction check failed because the sender was not authenticated when sending to this group};{MSG=};{FQDN=};{IP=};{LRT=}]

But when an email coming directly from an internal usermailbox the email is distributed to the members of the DL. However, message trace still shows that it fails and was dropped.
Message trace error: Reason: [{LED=250 2.1.5 RESOLVER.GRP.Expanded; distribution list expanded};{MSG=};{FQDN=};{IP=};{LRT=}]

I tried to set RequireSenderAuthenticationEnabled to false but did not resolve it.

Note: the sender's email domain is different to the DL but both domains are internal.
Dear All

                I have migrated 10 mailboxes to Office365 from on premise exchange, but still haven't changed the domain to abc.com as default yet, and I see the migrated mailbox show keith.li@xxxxxx.onmicrosoft.com , and I tried to login to O365 portal with keith.li@xxxxxx.onmicrosoft.com and try to login with on premise active directory user password, but it doesn't work, any idea ?

My Outlook 2016's new emails notifications arrive quite late:
did not time them exactly but all of them pops up about 30 mins after actual email arrival;
attached is one such notification.   I'm currently on O365 Exchange.

I recall previously when using Outlook 2010 (on-prem MS Exchange), notification is

However, meeting Invites' reminder in my Outlook 2016
pops up quite timely
Hi - Have a strange issue with Outlook and have tried (i believe) everything, yet the problem persists. So we are using Outlook with hosted exchange. The issue is that randomly we get a pop-up asking for the password for the account...At first we added it and it was ok. Then it got to the point it was doing it every other day which became annoying. As soon as I added the password it would be fine, for a day or 2. This is what I've done so far:

1. Upgraded from Outlook 2010 to 2016
2. Created a new outlook profile
3. Went into the control panel/credential manager, remove credentials for the outlook account and added again.
4. Reset the email password

Of course, none of the above worked permanently. Anyone have any ideas what would cause this and how to fix it?
I have fortimail 400E , I have a problem with Russian mails a lot of emails as below in attached use my firewall as relay , i follow best practice and many other resources in configuring my forti how I can solve this issue
An end-user has scanned in an email from a UPS store, it was split into several messages. It makes it through Proofpoint, then to our internal anti spam appliance Mailgate. Mailgate tried to deliver it to Exchange but Exchange seems to be rejecting it. I don’t think it’s the size but here is the message on Mailgate:

       Failed [host EXCH01.srtll.COM[] said: 554 5.6.1 Messages of type message/partial are not supported (in reply to end of DATA command)]

Any ideas?

HELP!!  Migrating to office exchange 365.  Most users use webmail only, Some Thunderbird imap, some Outlook 2010 pop.  What is the best painless way (or tool) to migrate all email, contacts, calendars etc to exchange server?  The process seems daunting :-(  thank you.
