Exchange 2010 Retention Policies
-
Monday, April 30, 2012 4:54 PM
i've set up retention tags for both the deleted and sent box for 90 days (delete and allow recovery). I set up the policy, attached both tags and attached a few mailboxes to them. I let it go for 24 hours so the assistant manager would kick in, when it didnt i manually ran it with the start-managedfolderassistant cmdlet and it still doesnt seem to be working. I've checked the event logs they are clear, it says the managed folder assistant completed successfully.
The mailboxes were upgraded from 2003, not that it matters but most people are using outlook 2003 but that shouldnt affect the actual mailbox. The cals are standard. Not sure where to look next. Any help would be appreciated.
Exchange is sp1

Lets run the mfcmapi and lets take a look on following property on the email
PR_LAST_MODIFIED_TIME - Make sure this value is more than 90days old
Please go through this to understand how message age is calculated

Open up Mfcmapi
Click on Session n select Logon and display store table
Select one of the user profile whom you think it has mails from more than 90days old
Double click on the mailbox to open store
Expand Root mailbox - IPM_SUBTREE or Top of information store
Right click on Sent items folder and click on Open contents table
Now you will see all the mails which are in sent items folder
Now select the message which you think is older than 90days and look for property PR_LAST_MODIFICATION_TIME

thank you! i will be doing some testing with various users, i've turned the policies back on, with sp1 i believe it runs continously but i'll probably do it manually on one mailbox just to see if it stamps the mail differently. i appreciate your help, i'll let you know, probably tomorrow, what i find in my tests.

well it just doesnt make any sense...as a test i set up a Sent items policy to remove them after 1 day...within a couple hours it updated my sent box with that policy and wiped anything older than a day out. So with that result it kind of takes the idea away that it wont time stamp them until the policy is issued. If that were the case it shouldnt have deleted them until the next day.
I did find items in my deleted box that were "last modified" more than 90 days ago so the policy should have wiped them out. Currently i have the 90 day deleted and sent items set up for the entire network.
Very confusing!

As far as I know, there are some problems with Retention Policy in Exchange 2010 SP1. You can install the latest patch to have a try.
http://www.microsoft.com/en-us/download/details.aspx?id=28190

I also remember a case that it's Outlook display problem. You can try another version of Outlook of use OWA to confirm it's not a client problem.

Hello Brice,
Sorry for the delay In getting back to you on this issue,
In Exchange 2010 the Retention Age is calculated in a different way, the retention age of mailbox items is calculated from the date of delivery. When the Managed Folder Assistant processes items in a mailbox, it stamps a start date and an expiration date for all items that have retention tags with the Delete and Allow Recovery or Permanently Delete retention action.
Say if you have message in a inbox and Inbox don't have any Retention policy applied, And if the user deletes the item it goes to the deleted item folder. When the MFA run it find this items doesn't have a start date, So the MFA stamps the Start date and the expiry date. The item is removed based on this expiry date.

Hope this helps.
Thanks
