I've tried everything in suggested in this post - http://answers.microsoft.com/en-us/office/forum/office_2010-outlook/when-you-send-an-e-mail-message-from-a-shared/557b3fbc-ad15-4f8c-abf2-9337effa28da
We had no problem with the registry key when we were using Outlook 2007 on Exchange 2007 server on Vista.
We have updated to Office 2010 ProPlus SP2
Windows 7 Enterprise SP1
Recently migrated to Exchange 2013 mail servers
We are not allowed to use exchange cache mode.
With OLK 2007 had no problem with using the registry key and didn't have to use cached mode.
If turn registry key 1 for on, the sent message stays in the Outbox, doesn't go to users sent items or the shared mailbox sent items. If I change the value to 0 message does get sent out but not sitting in the outbox, but stores it in the User mailbox sent items not in the shared mailbox sent items.
I've installed the hot fix, no change, I tried everything suggested and the sent item will not store in the shared mailbox, is this a problem with the Exchange 2013 mail servers.
