Hi lukemiller101001

What is the current Online Archive size for the impacted user, is auto-expanding archive enabled?

To check the current archive size for a given user, the following PowerShell can be used:

Get-MailboxStatistics -Identity <user> -Archive | Select-Object TotalItemSize

To check if AutoExpandingArchive is enabled, the following PowerShell can be used:

Get-Mailbox -Identity <user> | Select-Object AutoExpandingArchiveEnabled

"Each Exchange Online Archiving subscriber initially receives 100 GB of storage in the archive mailbox. When auto-expanding archiving is turned on, additional storage space is automatically added when the 100 GB storage capacity is reached. This incremental addition of storage space continues until the archive storage reaches 1.5 TB."
