Dear TechNet-Forum,
we are running Office 365 and want to enable the automatic archive function for different O365 - Exchange mailboxes.
I tried it with my own mailbox.
Step 1 : Activate Online Archive (Online Archive is also visible in Outlook)
Step 2 : Create a Retention policy with the standard retention tag for 1 Year Mail Move to Archive (not sure whether this is the online or the in mailbox archive folder?!?!)

Step 3: Assign the new custom Retention policy against a mailbox in Exchange Online Admin Panel

Step 4: Run command: Start-ManagedFolderAssistant -Identity xxxxxx
Step 5: Wait some days
But nothing happen.
Also when assigning a rule in the outlook app itself against the inbox with the 1 year retention policy, nothing is happen:

Thank you in advance for your support
