E2K10 SP2: Thanks for the new custom attributes!

One of the nice new things that Microsoft introduced in Exchange 2010 Service Pack 2 did not make much news. There are 30 new extension attributes (aka custom attributes). These are msExchExtensionAttribute16 -  msExchExtensionAttribute45.

Note, these are NOT editable from the Exchange Management Console nor the Set-Mailbox cmdlet,  But, they are flagged for Global Catalog replication, they are assigned a mapiID and they can be added to the details templates!

Exchange 2010 database space not being reclaimed quickly

  We have seen an issue in our environment where deleted space is not being recovered very quickly.   The database white space reports are generally very small, yet if we move all the mailboxes off the database, delete/recreate the empty database, and then move the mailboxes back, we can reclaim hundreds of GB.  As an example, in a 700GB database, we cleaned it up and it ended up being 275GB.

  We use Enterprise Vault and the problem is related to the fact that Exchange 2010 SP1 was not reclaiming the storage correctly.  Microsoft has resolved this in Exchange 2010 Service Pack 2 RU1.  (We were still running SP1 due to the difficulty in quickly applying service packs and updates in our environment.)

 Bottom line is that you should get your E2K10 environment up to at least E2K10 SP2 RU1.

Very cool Exchange organization report generator

I have been meaning to share this for a few weeks.  Very cool Exchange Management Shell script from Exchange MVP Steve Goodman. This script generates a nifty report of some useful information about your Exchange organization including about Exchange / Windows server versions, mailbox databases, sizes, and number of mailboxes.  Management digs this type of information!

Thanks Steve!
