hi guys...

i have a problem with retention policies. i've already read zounds of forums and information and still with no luck to explaining why it's happening.

what i try to achieve is to automatically delete messages older then 1o days on a mailbox. this is used for some alerting and notification. what was done:

- a retention tag has been created 'autoDelete'. tag type: inbox, age limit: 1o days, action: permanently delete

- retention policy created linking 'autoDelete' tag with the mailbox

- checked mailbox with powershell:

UseDatabaseRetentionDefaults  : True
RetainDeletedItemsUntilBackup : False
RetentionHoldEnabled          : False
EndDateForRetentionHold       :
StartDateForRetentionHold     :
RetentionComment              :
RetentionUrl                  :
RetentionPolicy               : Auto Delete Postmaster
RetainDeletedItemsFor         : 14.00:00:00

- force SFM with Start-ManagedFolderAssistant for the inbox

..nothing. no message is deleted, i don't see any message tagged, and choosing properties of the inbox folder in outlook do not show any RT policy assigned.

what am i missing?

any help appreci

By default retention policy will delete items only when the mailbox size reached more than 10MB. if the mailbox size is below 10MB, retention policy will just mark the item for deletion and when the mailbox reaches 10MB it will then delete the marked items.

yep. already read about such nuances. this an existing mailbox with >6ooMB of emails. more over in the case you are talking emails are tagged but not moved. here they are untouched. i also checked if RPT are working for existing emails or only for a new once. what i found is that in on-premise Ex it should work for all emails - automatically with existing once. in Ex online RPT are applied only for new items. 

is that correct?

Hi Leliv,

Please run the following command and check if the "autodelete" tag had been linked to the policy:

Get-RetentionPolicy "Auto Delete Postmaster" | FL Name,RetentionPolicyTagLinks

In addition, I also recommend you create a personal tag and manually apply to inbox folder, messages that have a personal tag applied are always processed based on the personal tag's settings.

Best re

apparently they are not - the list is empty:

[PS] C:\Windows\system32>Get-RetentionPolicy "Auto Delete Postmaster" | FL Name,RetentionPolicyTagLinks

Name                    : Auto Delete Postmaster
RetentionPolicyTagLinks : {AutoDelete10days}


[PS] C:\Windows\system32>

i'll try with the personal tag but this is not what we need - there are many 'special purpose' mailboxes in several departments. users for those are disabled and mailbox is shared between several users. manual configuration may be workaround, but i would really understand why the heck it's not working O_o'

after deleting some emails under mbx limits - all the rest of the mails has been tagged. seems that that was the reason!

another nuance to be added on the list ...

thx!
