Looking for a way to get a count of individual Outlook folder items (emails)
We are migrating from on-premise Exchange 2010 to Office365, looking for a way to get a count of emails in each folder/subfolder on each side so we can verify that the migration moved all the emails.
I am sure there must be some way to do this in Powershell.
The PowerShell components of Exchange - either on-premises or hosted - aren’t amazing at “cracking open” a mailbox to get at its contents. Do you have a way of doing this against your local Exchange server by using PowerShell?
I was able to find this script which works on a on premises Exchange, have not had a chance to test it against Office365 yet since I am fighting a number of “fires” today (I believe this is from Shay Levy):
function Get-MailboxFolder($folder)
{
“{0}: {1}” -f $folder.name, $folder.items.count
foreach ($f in $folder.folders)
{
Get-MailboxFolder $f
}
}
