After removing SID history target users can not access their mailboxes anymore -
Description
In some complex migration scenarios involving the merging of accounts using different migration products (QMM, EMW, DMW) the SELF permission may be missing from the Mailbox Rights on the source and or target mailboxes.
As a result target users will loose the ability to access their mailboxes after SIDHistory cleanup. How can this be resolved? -
Résolution
The problem can be fixed by using the Exchange Processing Wizard, selecting migrated user objects and processing their mailboxes (the target Exchange server) .
Alternatively, the AD Processing Task can be used with selecting Processing Options - Process Exchange 2000 Directory Permissions - Mailbox Permissions.
When using both wizards it is important to select objects, if no objects are selected the wizard will apply to absolutely all migrated objects and this might cause a slowness or even a failure when executing the wizard.
