Deleted and Junk mail folder won't delete after X days
- Retention policies is the way to go, however you need to use the "old style" Exchange retention policies, as only they can target specific folders. Go to the Compliance portal > Data lifecycle management > Exchange. Under MRM retention tags, make sure you have a "Deleted items" tag with the corresponding action/duration. Then under the MRM retention policies tab, make sure the Delete items tag is added to any policies currently assigned to your users. Rinse and repeat for the Junk email tag.
VasilMichevHey Vasil, thanks much for the feedback.
I see I do have some default retention tags already set, and I see Delete folder and Junk Mail folder included.
There is also a Default MRM Policy under the MRM Retention Policies tab, but this default policy doesn't seem to be applied to anyone's account on the server, including mine.
Is there a way to turn this Default policy on for all mailboxes?
Get-Mailbox | ft Name,RetentionPolicy
- Vasil, I realized I can apply this policy to all mailboxes in the Exchange Admin Center. Just select all mailboxes and select Mailbox Policies. This opens up more options to select which policy to apply.
So think I can take it from there.
Thanks for leading me in the right direction. VasilMichevNo other policies are listed other than Default MRM Policy.
Keep in mind, we had migrated from Exchange 2010 to Exchange Online. So not sure if the default policies were applied to the migrated accounts during migration.
Here is a snippet of the output of the Powershell command. All the users don't have the Default MRM Policy applied. Only these names with random numbers.
