Online Archive for Shared Mailbox Shows Main Mailbox SMTP Address, Not Shared Mailbox

Question

First off, we are running Exchange 2010 with Outlook 2010.  Exchange is running SP3UR5 and is stable.  Outlook has the latest updates.
We have archive mailboxes on all our production mailboxes.  We automatically archive items older than two years into these.  We have several colleagues who have access to one or more shared mailboxes, who had no issues when they were using a Windows
XP workstation.  However, when they were moved to our Windows 7 systems, their archive folders all show their primary mailbox SMTP address. If you click on a folder in the archive mailbox, the search bar shows the correct mailbox name. And to confuse
things just a little bit more, the primary mailbox for these shared mailboxes shows the correct name.  Has anyone else seen this, and, more importantly, does anyone know of a solution? TIA ...

Hello Willard,
As Andy mentioned, this issue is a known issue which resolved in Exchange 2010 SP3 RU2. I know we are currently running Exchange 2010 SP3 RU5, however to resolve
the issue, we need to install hotfix for Outlook clients as well. Please refer to the following hotfixes for Outlook 2010 and 2013:
Note: Exchange 2010 SP3 Ru2 or later will update the “OwnerSmtpAddress”
for all alternate mailbox. And before applying the following Outlook hotfix, we should have RU2 installed first.
Outlook 2010 hotfix:
Description of the Outlook 2010 hotfix package (Outlook-x-none.msp): August 13, 2013
http://support.microsoft.com/KB/2817574  
Issue description: You connect to Microsoft Exchange Server 2010 mailbox
by using Microsoft Outlook 2010. When you enable the feature that lets you view the online archive of a manager in Outlook 2010, two online archives that have the same name are displayed. To resolve this issue, you must also have Exchange Server 2010 Service
Pack 3 (SP3) Update Rollup 2 installed
Outlook 2013 hotfix:
Description of the Outlook 2013 hotfix package (Outlook-x-none.msp): August 13, 2013
http://support.microsoft.com/kb/2817503  
Issue description: When you enable the feature to see the online archive
of the manager in Outlook 2010, two online archives that have the same name are displayed.
After apply both update for Exchange server and Outlook client, the issue will be resolved accordingly. And I recommend to install the latest updates for Outlook
clients:

Moreover, the issue will affect the “auto-mapping” archive mailboxes, since the issue only affect few users, please check the differences on the Outlook client side,
and make sure the version and patches/updates are the same. If needed, we can first remove the auto-mapping full access permission, then re-add non-auto-mapping full access permission, at last, add
additional mailbox from Outlook manually, thus it will not diplay same name for the archive mailbox we access.
Remove the full access permission:
Remove-MailboxPermission –Identity “Shared_mailbox” –User “affected_user_mailbox” –AccessRights FullAccess
   2.Re-add the full access permission with non-auto-mapping:
Add-MailboxPermission -Identity “Shared_mailbox”
-User “affected_user_mailbox”
-AccessRight FullAccess -InheritanceType All -Automapping $false
   3. Then on the affected user mailbox outlook side,
add additional mailbox manually.
Please refer to above information and if anything unclear, feel free to let me know.
