Exchange Online Archive–Counting Archives

If you are using Exchange Online Archive and what to get a count of the number of users with an archive, or a list of the users with an archive, then the following PowerShell scripts will give you this info:

List all users with an Exchange Online Archive:

Get-MailUser -ResultSize Unlimited | where {$_.ArchiveName -ilike “In-Place Archive*”}

Count all users with an Exchange Online Archive:

(Get-MailUser -ResultSize Unlimited | where {$_.ArchiveName -ilike “In-Place Archive*”}).Count

Both of these PowerShell cmdlets need to be run in Exchange Online via Remote PowerShell.
