Exchange 2010 retention policy and mailbox quotas

Posted on 2014-02-19

In Exchange 2010 if  I create a retention policy and assign the 5 year delete tag to the policy, will the users mailbox size never be reduced when they delete items during this 5 year period?  Or, are the deleted mailbox items moved somewhere else on the server during this 5 year period?  

It seems a user's mailbox is 1.6 GB, but when I look through their items, I just can't see how it adds up to 1.6.  I tried to use a powershell script I found online to create a report of all items in the mailbox, but had trouble trying to get the data exported to a file.  If anyone has any suggestions on how to accomplish this, it would be helpful.

5 years tag is for deleting older than 5 years email automatically, not for manual deletion.

What is the  retention action in retention tags?
Is it DeleteAndAllowRecovery or PermanentlyDelete ?

For space recovery, you retention action should be PermanentlyDelete.

And, if you create this retiontion policy, did u run ?

I downloaded the Lepide Reporter you suggested from the exchangereports.net link and it is very informational.  Haven't had a chance to run the export mailbox report script yet, due to other pressing issues, but I do intend to try it.
Thanks for the feedback.
