How can a user see the size/usage of their Archive mailbox?

Currently there only seems to be a way for ADMINS to see the size/utilization of a given user's Online Archive mailbox, and we need a way for the user to see this so they can effectively manage their item storage.
A user is able to browse to here to see a storage overview of their various folders, but this only shows the user their PRIMARY mailbox, and there is no mention anywhere of the Online (In-Place) Archive mailbox that they have been provided to use:
https://outlook.office.com/mail/options/general/storage

Only an ADMIN is able to browse to the Exchange Admin Center or the ECP and view the size of a given user's Online Archive, or this can also be done via powershell, but the USER has no way to see this info. This seems to be an oversight that needs to be corrected. Online archive has a limit of 100GB so the storage overview page needs to extend to include the archive mailbox to show the user the size of ALL of their folders.

    As michev said, you need to check the size from Outlook client for now:

    About the size limitation, M365 Business Premium is 50G:

    About the storage overview page in OWA, you can try to submit a feedback from the end of this article.

    Please note this information above as of 2025 is outdated. Currently Microsoft 365 Archiving, with a Exchange Online Plan 2 or above (or a Plan 1 with added archive license) has a maximum of 1.5TB of data storage for Archive purposes.

    Outlook will show the quota/current usage when selecting the Online archive, OWA indeed does not show this info.
