I'd seen a post on the forums for this issue before but there was no resolution, the user just came back to her machine 3 days later and the issue had been resolved. (so jealous).
I have a user with the above config of Outlook and Zimbra OLK who is having an issue of mail being stuck in her Outbox folder. Send/Receieve doesn't remove it, Outlook is online and I've tried various suggestions. Even removed the users profile, uninstalled Office 2007 rebooted and completed a fresh install then added the profile again...she's still having the issue. She can still receive mail and I've unchecked then checked the 'send immediatley' option within Send/Recieve...still the same.
I've tried repairing/re-installing the OLK also...
Any ideas/help would be greatly appreciated as I'm at the end of my rope with this one, not literally
p.s. I should also add that the user views and 'send's as' mail from additional 'generic' mailboxes as do the rest of her department who are configured in the same way with same software versions, all using multiple personas.
