Non-unique proxy address in exchange online

Question

Hello,

We are having a hybrid environment and O365 licenses are assigned through a security group. So, whoever present in the group will obtain the O365 license.

However, for one of the user, there is some issue. When we check the status of license for this user, we are getting "Non-unique proxy address in exchange online" This is the status shown in azure AD. On the other hand, in the M365 admin portal, it shows unlicensed. **
We tried to find duplicate proxy in the tenant, however it went vain. We ran following PowerShell command:

get-recipient | where-object {$_.emailaddresses -match  "******@contoso.com"} | fl

Can someone help me how to resolve this?

Hi @Surya kumar ，

Run the PowerShell Command below instead against Exchange Online and see if there would be any findings:

Get-Recipient ******@contoso.com

You can also refer to the steps in the link below and see if the error is due to any mail enabled public folders that use the conflicting proxy address: Check for and remove any conflicting proxy address in Microsoft Entra ID
