Retention Policies DPT and RPT need help to understand

This is my first experience with Exchange online retention policies.   According to this https://docs.microsoft.com/en-us/Exchange/policy-and-compliance/mrm/retention-tags-and-retention-policies?vi...

I understand that . But let me rephrase my question.

 

Can an item have two tags, one  for "move to archive" and another for "delete"?

 

In my case, that I described in my post, I have items in Inbox folder that inherit RPT "2-day delete" and they are considered as tagged. But now I apply DPT "1-day move to archive" to already tagged items.

That is what confuses me: "..Items within a folder inherit the tag applied to a folder, or the default tag if no such tag exists..."

 

I realize that my test proves that an item can have 2 tags but before applying retention policies to the production mailboxes I would like to get a confirmation from experts.

 

EDIT:

 

Two DPTs (one "move to archive" and second "delete") can be applied to untagged items. So basically it confirms that 2 tags can be applied to an item. And now just DPT and RPT (of different actions) need to be confirmed.

Yes, you can have two tags with different actions applied. That's why in clients you see them as "Archive policy" and "Retention policy". And it's also used for scenarios where you want to clean up your primary mailbox but keep the items for a while longer in the archive.

    If I have one retention policy  which contains archive tags (DPT or/and personal)  and delete tags (DPT or/and RTP or/and personal) and only one policy can be applied to the mailbox, I do not see separate policies as mentioned in Outlook. I understand what Outlook means by these separate policies but it would be much more clear if  documentation explained this correlation between policy tags and Outlook different policies.

     

    And I understand how it should work in theory....

    But, unfortunately, my test eventually failed.

    Some messages were moved to the Online Archive but they were not deleted after "Inbox 2-day delete" RPT and they are still in Online Archive/Inbox.

    Some messages are still in the account mailbox/Inbox, though "1-day move to archive" DPT is long past due.

    How can I troubleshoot this problem?

    If this is the right way to troubleshot, it seems that the Inbox RPT tag has not been applied to the mailbox.

      When using -Mailbox parameter, RPTs will NOT be returned. All you need to check is which policy is assigned to a given mailbox, you can get the full set of tags therein.

        How can I troubleshoot this failed test? Is there any log or tool?

         

        UPDATE:

        Start-ManagedFolderAssistant -FullCrawl -Identity <mailbox>

        Didn't do anything on messages in Online Archive/Inbox

         

        Those messages that were supposed to be moved to Online Archive (1-day move to archive) were deleted from the account mailbox by the 2-day delete RPT, I believe.

         

        The results have not been very encouraging.

         

        "...The Managed Folder Assistant is a throttle-based assistant. Throttle-based assistants are always running and don't need to be scheduled. The system resources they can consume are throttled. ..."

        Who knows when it runs ...

        I do not know if this is my short age test to blame. Will try to submit a support ticket.
