I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is the mailbox running in cached exchange mode?

Have you tried recreating mail profile?

Attila-RobertAuthor Commented:
No, I haven't tried yet recreating mail profile, ultimately will do.
Also what difference will running in cached, or not cached mode?
Mark GalvinManaging Director / Principal ConsultantCommented:
Cached mode means that the client doesn't keep the connection alive, in essence. It checks with the server periodically for new email etc. downloads the changes to a local OST file.

Non cached mode means direct connection to server.

In my Citrix environments I always go non cached.
