Cannot access mailbox for Administrator after upgrading to Exchange 2007
Posted on 2007-03-18
We have just migrated to Exchange 2007 from Exchange 2000. We moved all the mailboxes and everything seemed to go well. When we try to setup an Outlook client or even OWA we cannot access the Administrator mailbox which also has an alias for postmaster. All the other users seem to be working fine from what we can see. When we open outlook it asks us for the username, password, and domain name. When we type in the information it comes back with an error stating "Your logon information was incorrect..." I am logged in to workstation as the administrator. When I try and use OWA I get the following:
Outlook Web Access could not connect to your Microsoft Exchange mailbox. If the problem continues, contact technical support for your organization
Exception type: Microsoft.Exchange.Data.Storage.ConnectionFailedTransientException
Exception message: Cannot open mailbox /o=First Organization/ou=First Administrative Group/cn=Recipients/cn=Administrator.
Any Ideas would be greatly appreciated.
