Hello ,

I have an Exchange 2007 Installation in a multinode enviroment. Its about 3000 users. Suddenly today a user cannot connect to his mailbox. He can connect without problems from OWA but with mapi in outlook 2010 it keeps asking for Password.

I try to setup his account in a new computer and outlook profile and when setup finishes and outlook starts for first time i take the error " Cannot open your default email folders . You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your outlook data file (.ost) " 

Any ideas please? I don't know what to do .

Thanks

Have you tried disabling cached mode so it doesn't use an OST? Any errors if you do it that way?

this problem basically I have seen when all the users are impacted after restarting the
Microsoft Exchange Client RPC Access  fixed the issue. But in your case its impacting to only single user so may be .ost file has been corrupted. Did you check with new outlook problem or check from different machine. Is user using any pst file chances that is also causing the issue

If this issue occur on one user, I suggest you follow these steps to have a try:

 

1.       Go to this path c:\users\%username%\appdata\local\Microsoft\Outlook.

2.       Now look for any .ost files and delete them. ( Please backup the .ost file before you delete them or rename the .ost file. Eg; change to .ost.old)

3.       After you deleted the .ost file, restart the Outlook.

Standard tests - you have done the first, which is to test on OWA.
Second test - does the problem follow the user to another machine. If yes, does the problem follow if you move the mailbox to another database?
If yes, then the problem is most likely with their AD account.
