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?
Hi @Haza Hafiz Riski,
Thanks for your response.
Yes, you're correct. With Microsoft's auto-expanding archive feature for Exchange Online, once the storage in the archive mailbox reaches approximately 100 GB, Microsoft will automatically begin to expand the archive storage. However, the expansion process might take up to 30 days, but it generally happens within a seven-day timeframe under normal conditions.
If your migration failed due to insufficient storage, it is likely that the archive expansion had not completed. You'll need to wait until the archive storage has been expanded before continuing with your migration.
Please feel free to contact me if you have any queries.

However, with this user, the storage in the archive mailbox had reached 100 GB and I had waited more than 30 days to run the migration again. I guess after I waited more than 30 days the archive storage will automatically expand to 1.5 TB.

Hi @Haza Hafiz Riski,
Thanks for your response.
The auto-expanding archive feature in Microsoft 365 should indeed start expanding the archive mailbox once it reaches 90 GB, and it can take up to 30 days for the additional storage to be provisioned. However, the expansion process is incremental, and the mailbox won’t immediately jump to 1.5 TB. Instead, it will gradually increase as more storage is needed, up to the maximum limit of 1.5 TB.
If you’ve waited more than 30 days and the storage hasn’t expanded as expected, there might be an issue that needs further investigation. Here are a few steps you can take:
Get-MailboxStatistics

Hi @Jake Zhang-MSFT ,
Is there any way to check the available current mailbox archive storage?
Hi @Haza Hafiz Riski,
You can use the Get-MailboxStatistics cmdlet with the -Archive parameter to retrieve archive storage usage details.
Get-MailboxStatistics -Archive -Identity <UserMailbox> | FL DisplayName, TotalItemSize, ItemCount
Replace <UserMailbox> with the email address or alias of the user whose archive storage you want to check.
Sorry for delay respon. Below is the result:
I waited for more than 30 days but it seems that additional storage is not yet available.
