Exchange Mailbox Limits – Export None Default Quotas to CSV

5d05eb33135798a962e3199db1fa4a4c

If you are using Exchange in your organisation and have multiple administrators, then you may need to keep an eye on mailbox limits. In most organisations the mailbox limits are set by default on the database, however you can change the limits per mailbox.

So, if you want to see which mailboxes do not have the default database limits set, then you can open Exchange Management Shell (EMS) and run the following command:

get-mailbox | where {$_.UseDatabaseQuotaDefaults -ne $true} | Export-CSV C:\Mailboxes\NonDefaultLimits.csv

This will run and export the mailboxes without the default limits set to a CSV file at the “C:\Mailboxes” directory as stated. If you want to change this location or filename you can.
