Checking if a mailbox is valid using Exchange Management Shell

In some scenarios we need to check if a mailbox database is valid on Exchange Server, this kind of validation is useful when migrating/transitioning mailboxes.

Solution


In order to validate mailboxes we can use an if clause to validate if the mailbox exists or not in the environment, and based on that we provide a brief description. The following cmdlet can be used.

$users = Import-csv File.csv

$users| foreach { if (-not (Get-mailbox $_.Alias -ErrorAction silentlycontinue)) {write-host $_.Alias ” does not exist! Please correct it! “} else {write-host $_.Alias ” exists”} }
