SBS 2003 to SBS 2011 Migration mailbox access issue.


  • I migrated an SBS 2003 server to SBS 2011.  At one point, the mail was still on the legacy machine, and the users were able to access their mailboxes using Outlook.  I then moved the mailboxes to the new mail server instance (Exchange 2010).  Now the users can't access their mailboxes, though nothing else had changed.  I am sure that this is to do with incorrect extended permissions on the mailboxes.

    So, here is an interesting thing.  If I create a new user, this issue doesn't arise.  In fact, no issues at all.

    Here are some of the symptoms. 

    The existing users are prompted for a user name and password, and despite this, still can't access their mailboxes.
    I have checked for inheritance in adsiedit under folder hierarchy, but it is ticked already.

    When I run get-mailboxpermission -Identity username,  it shows that the user IsInherited = False and Deny = False.

    Any ideas?  Getting desperate, 4 days without email for about 15 people.  Ouch!
