Is it possible to track where a mailbox for a specific user existed for a specific backup date?
Use the Mailbox History information that is stored on the Tivoli Storage Manager Server to determine when a specific mailbox was moved.
The mailbox history processing task gathers information from the Active Directory service for all the mail users within the entire Exchange environment. The information that is gathered includes references for the location of the mailbox for each user. This information can be used to automate the mailbox restore processing when mailboxes are moved from one database/server to another database/server between backup operations.
To show the information that is saved during the Mailbox History backup, enter the following command from the Data Protection for Exchange command-line interface:
tdpexcc q tsm /showmailboxinfo
