Deleted items in Outlook and MRM policy
Just to add that the Default MRM Policy in ExO should *not* have the Deleted Items tag in it, they removed this one few years ago. If you want to ensure that items in the Deleted Items folder are automatically removed after some time, you need to rename the default policy or create a new one with that tag and assign it to users. Here's the blog article announcing this change: https://www.microsoft.com/en-us/microsoft-365/blog/2015/02/20/extended-email-retention-deleted-items-office-365/
The first.
The second is controlled via Set-Mailbox -RetainDeletedItemsFor
The default value for Office 365 Exchange Online is 14 days with a maximum up to 30 days.

- Thanks, so just renamed the default to something else and add the deleted items tag didnt work, does this means i need create custom policy and then apply it ?
Hm, well I usually create a new policy anyway, but afaik renaming the default one should work.
