Another object with the same value for property proxyAddresses already exists.

Copper Contributor

Receiving this message when I try to restore a Microsoft 365 group.  I feel like I am 99.9% sure I do not have another object with the address I am trying to restore.


Any suggestions?

Hi Paul,

Can you search for the ProxyAddress via Powershell?

Get-Mailbox -Identity * | Where-Object {$_.EmailAddresses -like 'smtp:username@domain'}
