I had a old user, yesterday logging into her NT account and when you opened Outlook 2003, she received the following message:
"Unable to open you default e-mail folders. The Microsoft Exchange Server computer is unavaiable. Either there are network problems or the Microsoft Exchange Server is down for maintenance."
OWA doesn't work on her logon either. But there is nothing wrong with her email account as I (exch admin), can access her inbox with my user account.
I have tried the following:
I deleted her Outlook profile and recreated, no success
I deleted her Windows profile, no success
l logged someone elses account onto her computer and they're Outlook and OWA works fine on her PC, therefore it is not a application or os problem.
I have logged her on to another computer and the error follows her.
I checked the mailbox rights on her account and she has full mailbox acccess
I removed her email account from her user account in AD, recreated it. same problem.
I created a copy of her account and the problem is still there.
I created a new user account, transferred her smtp address over to the new account to see if it works and it did. I then had to transfer all her permissions over.
Great, but the problem is.... it has now happened to 7 other users! Exactly the same.
Why is this suddenly happening? What is casing this? and is there any other solution to this problem apart from creating a new account and transferring all the permissions over ?
I can do this for these 7 users, but if it becomes a breakout, I will not be able to deal with it.
