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 a couple of options for doing this:
- Use Outlook to open the archive mailbox and delete the data manually.
- Delete the archive mailbox altogether (and then provision a new one if you still need archiving).
- Use Microsoft 365 retention policies to delete data after a certain age. See https://learn.microsoft.com/purview/set-up-an-archive-and-deletion-policy-for-mailboxes for details.
Hope this helps!
