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

[Paul_Kirkpkirk001]

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?

Thanks.

Hi Paul,

Can you search for the ProxyAddress via Powershell?

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