Cause

During the process of leavers migration we creating user in O365. For this creation we using First Name and Last name from Enterprise Vault archive to construct user UPN/SMTP and create the user.

If those two fields are not populated in Enterprise Vault for the archive we using Archive Name to construct required values.

Sometime it can happen that ArchiveName is very long so constructed name exceeded the limit.

Solution

You need to update the UPN in few tables to shorter version of the name.

1. Update LeaverTempIdentifier column in the LeaverMappingSelection

2. Update UserPrincipalName and PrimarySMTPAddress column in the Mailboxes table

NOTE: it's preferred to use same value for all three columns update, e.g. Leaver_shortname@contonso.com
