Dear folks,
Issue was with Symantec Outlook Add-ins
Issue:
I had the problem with outlook 2010, exchange2010.
Emails that I send and then edit in the outbox folder will not be sent ! (they are now stuck in the outbox folder with date=none)
The solution was to play with the outlook add ins.
I found that Symantec Endpoint Protection (antivirus) outlook add ins caused my problem.
I had disabled it, restarted outlook, and my problem is now solved !
I can now edit mails in the outbox folder and they will be sent as they should !
However my issue is not yet resolved, I have opened a call with Support so that a good resolution can be found hence symantec outlook add-in be enabled and works fine.
Will keep you all posted upon complete resolution.
Many thanks though.
