Hello, one of our clients has a an Outlook client issue after migration from Exchange 2007 to 2013.

Bascially,  mail is stuck in outbox of the main mailbox when sending mail using the main mailbox when there is an additonnal mailbox open. This issue is seen only, as far as we know, on Outlook 2010 clients under Windows XP.

It seems that i am not the only one in this situation, see:  http://www.reddit.com/r/sysadmin/comments/1dwhfm/exchange_2013_cached_mode_additional_mailbox/

We are currently tring to use the solution provided in the end of the reddit article :

A- by re-applying permissions with "add-mailboxpermission" and playing with the automapping attribute.

B - It seems too that removing the additionnal mailbox from the profile and adding it back, solves the issue.

But at this point, we  cannot say that either A or B or a combination of both actions A and B solved the problem.

When we have more information, we will comment.

However, if any of the MS Engineers had an idea for troubleshoooting steps, we are interested, and we thought that reporting the issue may be important for the community.

And FYI, certificates are OK, outlook anywhere is OK, autodiscover OK, OAB download is OK, all URI are OK, no Outlook authentication popups, no stale connections (CTRL+SHIFT + right click outlook -> connection state are all OK)

The Exchange 2007 is not yet decommissionned. only powered off.

Any idea welcome !

Hi,

To narrow down the issue, please keep the additional mailbox opened and try the following points:

1. Confirm if only one Windows XP user encountered this issue.

2. Please setup this problematic user on Outlook 2010 clients with Windows 7 or Windows 8 machine, then confirm whether the issue continues.

3. Send test messages in Outlook Online mode and check whether the message is stuck in Outbox or not.

4. If the issue doesn't occur in Online mode, please create a new Outlook profile in Outlook and check whether the issue persists.

Regards,

Check this out if this helps.

Hello, Some diagnostics and troubleshooting was made.

After all debugging, we can say that :

We have to run the following commands :

$user = user_to_access_the_mbx

$identity = shared_mailbox_identity

Add-MailboxPermission -Identity $IDENTITY -User $USER -AccessRights Fullaccess -InheritanceType All -Automapping $true

Get-Mailbox $IDENTITY | Add-ADPermission -User $USER -ExtendedRights Send-As

And then we have to recreate the profile, and then the mailbox is automapped; and the problem is solved.

I was said too that using users for granting permissions instead of groups seems to work better.

But i am not 100% sure of this requirement.

---------

If there is no other solution than to recreate the profile, we may have to use PRF files to automate the profile generation process and a powershell script for re-adding the permissions in automap mode for all shared mailboxes.

Hi,

According to the further posting, the issue can be resolved by removing and re-adding full access permisison with Automapping feature enabled. The issue seems to be related to mailbox permission.

We can check the automapping feature in AD by the following steps:

1. Open Active Directory Users and Computers.
2. In Users, right-click robtepperman > Properties.
3. In Attribute Editor tab, pick up msExchDelegateListLink attribute.
4. Make sure the value is set to the user who has full access permisison to this mailbox.
Then check whether the issue persists.

Hi,
