Exchange Move Mailbox Experiences Part 3

In Part 2 I showed some details about Mailbox Rule corruptions that can disturb Mailbox Moves.

For this part the topic is Mailbox size, which can be an important factor in deciding which mailboxes you want to move first.

In my case the mailbox size was important because we agreed to move smaller mailboxes during the day but larger mailboxes only outside working hours.

For Exchange 2010 mailboxes it’s very easy to obtain the size using PowerShell.

    I wanted to know if I had really a corrupted mailbox or maybe even corruption in the store or another problem.

    So in this part I will describe how to break down the Mailbox Move Log.

    First go to the Failed Move Request and select Properties:

    Exchange Logo

    I am currently working on a migration project from Exchange 2003 to Exchange 2010.

    Most Exchange migration projects use Mailbox Moves to move the mailbox data to the new Exchange environment.

  • I am currently creating a PowerShell script that creates a user with all needed Active Directory attributes, Exchange mailbox, (TS) Home- and Profile directories and so on.

    In such a script you can easily get failures because of Active Directory replication.
