Hi Andrew,

Thank you for the quick reply. I did see that site, but

when I run the following PS command it doesn't find any reslults.

Get-Recipient -ResultSize Unlimited | where{$_.emailaddresses -like “*EUM:*removed*”} | fl displayname,emailaddresses

I haven't checked shouldn't it be $_.ProxyAddressess -Like not emailaddresses?

Hi Mark,

Either $_.emailaddresses or $_.ProxyAddressess are accpeted and return the same results.

    Andrew,
    The Get-UMMailbox | fl Extensions was very helpful. I see the ext "7832" I'm trying to apply assinged to another user. Can you advise the best way to change this? Can I just disable UM for the user with 7832.. then re-enable with the correct ext. Then attempt to enable 7832 to the correct user?
