Could you please advise if there is any way to delete the mailbox data that is currently stored in the online archive? Thank you.

Hi Thao_Dao_Phuong​, you have three options for this:
- Use Outlook to open the archive mailbox and manually delete the data.
- Delete the archive mailbox altogether (and then create a new, empty one if you need archiving).
- Use Microsoft 365 retention policies to delete data in the archive based on age (see https://learn.microsoft.com/purview/set-up-an-archive-and-deletion-policy-for-mailboxes for details).
Hope this helps!
