Can someone help write a powershell command that I can easily enable MAPI to 100 users in the same domain, note that not all users in this domain uses mapi, I have a list of the specific 100 user email addresses to enable the mapi.

Hi,

Try this script, I test it in my lab, and it works well.

$Export = Get-Content C:\Users\AdminAccount\Desktop\Mailbox.txt

foreach ($mb in $Export) { $mb | Set-CASMailbox -MAPIEnabled $true }

Before we run this script, save all users email address to txt file like below. In my script, I put this txt file to desktop. If you put this txt file to other folder, please edit the path in my script. And remember to replace the AdminAccount field to your exchange account in myscript.
