We use Exchange Online for our mail hosting with Outlook 201x. We have a shared mail account used by many different servers to send alerts out.
Address: ServerAlerts@mycompanyName.onmicrosoft.com From Name: Server Alerts
On each server, the alerting application sends mail via SMTP and explicitly sets the "from name" as "Server Alerts [Server Name]". However, this new name does not show in Outlook on the mail in the contact information at the top. Instead, we see the original name of just "Server Alerts". If I look at the mail properties, I DO see "Server Alerts [Server Name]" in the headers, so it IS there.
The kicker is that if I send a test mail to a GMAIL account, or to external people using Outlook on their own domain, they see the "Server Alerts [Server Name] from name on the mail itself.
Why is my explicitly set "from name" getting overridden by the default on our Outlook only? Is there a setting in Outlook that needs to be changed? I can't imagine there is an Exchange Online setting for this account that is incorrect since other mail providers do pass through the explicit name.
