How to use Translator for Outlook in intranet

Question

Currently, the mail server is using Exchange 2019 On-premise. and Outlook verison: Microsoft Outlook LTSC MSO(16.0.14332.20561) 64bit

When I try to use Outlook's Translate function, I get the error "we could not't translate your message at this time. Please try again later". Maybe it's because I'm looking at the internal network, but I wonder which Domain, IP address, and port I should pass through to use Outlook's Translate.

Answer 1

I'm sorry, but the Translator for Outlook feature requires an internet connection to work properly. It may not work when you are on an intranet or behind a firewall that blocks the necessary ports. According to the Microsoft documentation, the Translator for Outlook feature requires access to the following domains: api.cognitive.microsoft.com and api.microsofttranslator.com. You may need to allow access to these domains in your firewall or proxy server to use the Translator for Outlook feature.
