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.

looks like issue with permission.

They used to work great. This was all of a sudden, but what would the permissions issue be with? Thanks...
Is the account used for the mailbox backups still valid, and password not expired?

If they are, it's possible that the profile has become corrupt. I would recommend that you try to recreate the profile using the ProfMan utility ( )
