I have a number of mailboxes that have the alias formatted incorrectly. I want the alias to equal the samaccountname on all mailboxes. How can I do that with powershell? I tried the command below but it did not work. get-mailbox -filter {Alias -like "*"} | ForEach{set-mailbox $_.Identity -Alias "$($_.SamAccountName)"}

I don't think the user's samaccountname is a property of a mailbox object. Try this (not tested): get-mailbox -filter {Alias -like "*"} | ForEach{set-mailbox $_.Identity -Alias "$((get-user $_.distinguishedname).samaccountname)"} [string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

You'll get a warning (yellow text) when the account name and the alias are already the same. Adding a conditional so you don't try to change what doesn't need changing the warnings will go away. get-mailbox -filter {Alias -like "*"} | ForEach {if ($_.alias -ne $_.samaccountname) {set-mailbox $_.Identity -Alias "$($_.SamAccountName)"}} --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi DVDKEA, Said you want to change the alias to equal with the SamAccountName and the command provided by you cannot help you achieve your goal. Could you please paste the error when you run the command or describe detailed how it does not work? And I recommend you using the following script and try again. [PS] C:\>$list=get-mailbox [PS] C:\>foreach($item in $list) >> { >> $user=get-user $item >> $sam=$user.SAMAccountName >> Set-Mailbox $item -alias "$sam" >> } >> Please feel free and let me know if the issue has not been resolved. I am glad to have a further discussion with you. Best regards, Yang
