I have enabled AutoExpandingArchive on the tenant that I manage in the hope that I will get a storage limit of 1.5 TB. Is it possible to check the details of the Archive Quota size? Because what I know is that I can only check the status.

    You don't get the full 1.5TB quota at once, but by "increments". In addition, the quotas you see above are not valid, once you have AutoExpandingArchiveEnabled set to True, you should ignore them (as detailed for example here: https://learn.microsoft.com/en-us/purview/enable-autoexpanding-archiving#verify-that-auto-expanding-archiving-is-enabled)

    To get the actual usage, fetch the (set of) GUID for the aux mailbox in question and use the Get-MailboxStatistics cmdlet. You can find examples here: https://techcommunity.microsoft.com/t5/exchange-team-blog/office-365-auto-expanding-archives-faq/ba-p/607784

    Currently, I'm running an email migration to Microsoft 365 and on the destination email side I have enabled auto-expanding so that the Mailbox Archive Storage has exceeded 100GB.

    However, the migration failed due to insufficient storage.

    From the link you provided, it means that after the storage is full, we have to wait 7 days for the storage expansion process, right?
