Error
GroupWise login failed. Error: User not on post office Code: 53505.
Cause
This error occurs when migrating from GroupWise using a trusted key, and MigrationWiz is unable to find the user in the Source environment. GroupWise uses an Email Address and a Login Name, but those two values are not always the same. Instead, the Login Name is often the name of the mailbox without the domain.
Resolution
Confirm that the Login Name provided to MigrationWiz is the correct one.
