SUMMARY
Sometimes when administrators migrate users from Microsoft Mail to Exchange Server, the mailboxes migrate with no errors, but neither administrators nor users can log on to the new Exchange Server mailboxes. This occurs with both single-step and two-step migration, where administrators are telling the Migration wizard to make passwords from the alias names.

Usually, the administrator must enter a new password under User Manager for Domains in order to access the mailboxes.

There are no problems with the password generation of the Migration wizard. The common cause for this issue is a minimum password length set for the Windows NT domain, which is a larger number than the alias name of the migrated user. In these cases, the Migration wizard pads the password with lowercase "x"s. The password can be found in the Accounts.password file.



MORE INFORMATION
An example is a mailbox whose alias name is three letters long, like the initials of the user. This mailbox is migrated to Exchange Server, whose domain has a minimum password length of four. When the administrator (or user) attempts to log on to the new mailbox, he or she is denied with a "password incorrect" error message. To get into the mailbox, the administrator must either reset the password under User Manager for Domains, or enter the password with enough following "x"s to match the minimum password.
