Outlook conversation view when using Send on Behalf of Accounts

Question

Ok, so here's what I'm working with:
Have a group of users that were recently setup with a generic mailbox using "Sent on Behalf of" permissions. They can all view the account in Outlook (2010) fine and can send messages fine from it as well. We made the registry change on all machines
that causes mail they send from that account to appear in the "Sent Items" folder of the generic account instead of their own and that is working well. The only issue is that when attempting to use conversation views they will not work (you replied
to this message, you forwarded this message, etc.) now. As a test, I moved a few items from the Sent Items folder in the generic account over into the Sent Items folder of one of the users own Outlook accounts and the conversation views then works correctly
for those messages.
So basically, it appears as if the registry key change worked for changing where the sent mail from this account goes to, but Outlook doesn't realize that's where they are so conversation views won't work. Anybody have any ideas on this?

Answer 1

Hi,
I can reproduce this behavior in my environment. Outlook can organize
Inbox and other mail folders in conversation view, but Outlook can't organize emails in other mailboxes within one conversation thread.
When we set the registry to have Outlook save email in the "Sent Items" folder of the generic account, the sent mails are not in their own mailboxes. So in theory, it's the default and proper behavior of Outlook.
