Archiving in 365 is not working

We have an user on 365. He has a mailbox and an archive mailbox. We have configured that its mailbox has to keep every item younger than 1 year.

We see that items are moved to the archive mailbox, but there are still items in his original mailbox older than 1 year. Those items are not set to not archive them.

Now he is getting again the message that his mailbox is running full.

How can I check is everything is configured ok and why are some items moved and other items not?

It is probably not very clear to me.

Thanks for your feedback.

Kinder regards,

Kurt

    Hi @Kurt Stichelmans

    Welcome to our forum!

    It sounds like you might need to check a few things to make sure everything is configured correctly and to understand why some items aren't moving to the archive mailbox:

    Outlook Rules: Verify if there are any Outlook rules that might be moving items to the archive folder.

    Mailbox Size: Check if the mailbox size is less than 10 MB. The retention policy doesn't automatically run for mailboxes smaller than 10 MB. If it is, you'll need to manually run the Managed Folder Assistant.

    Retention Policy Configuration: Verify that the retention policy is correctly configured to move items older than 1 year to the archive mailbox.
