Email IDs are placed under 'example@domain.com' for couple of users?

Hi,

We use exchange 2013 CU5 hybrid of O365

Usually if any email from external IDs to internal user the email once received, will show as display name format - UserName/Domain/Department

The display name is set in the message headers. Please can you let me know what SMTP filtering you have in place before email gets to the user's mailbox and also post the message headers for an email with the issue. You can get this from the message properties using Outlook.

Also, have there been any changes to the receive connectors on the Exchange server? Please can you post the settings for the receive connector that external email is delivered to (Get-ReceiveConnector | fl).

Thanks.

Hi Manju,

Does the issue happens when your Exchange users receive message from all external domain senders, or specific domain senders?

Please run the following command to check the remote domain settings in your server side:

Get-RemoteDomain | fl

Additionally, please double confirm whether the issue happens to other users in OWA. Or this external sender is just added as Outlook Contact in client side.
