This article applies to:
- MailMarshal 11.2 and above
- Entra Connector
Question:
- How do I configure a proxy for the Entra Connector?
Procedure:
The Entra Connector uses the MailMarshal RPC Proxy service to connect to Entra ID. This service does not use the proxy settings configured in the MailMarshal Console.
To configure a proxy for the Entra Connector, use the https_proxy system environment variable.
You can provide a server name or IP address, port number, and optional authentication details.
The format is: setx https_proxy [protocol][<uid:pwd@>]<proxyserver>:<proxyport> /M
- On the Array Manager server, open an elevated command prompt.
- Enter a setx command similar to the following examples:
- setx https_proxy myproxyserver:8081 /M
- setx https_proxy https://myv2proxy.local:80 /M
- setx https_proxy mydomain\mmentrauser:supersecretpassword@10.10.10.10:8080 /M
- The expected response is: SUCCESS: Specified value was saved.
- Restart the MailMarshal RPC Proxy service. This will also restart the MailMarshal Array Manager service.
- Test the Entra connector. Any issues display as a red "toast" pop-up message in the console, and also in the MMRPCProxy log file.
Notes:
Other applications on the server that make automated web requests might respect the https_proxy variable. You can use the no_proxy variable to exclude sites from proxying.
If you are using a proxy that inspects HTTPS content (for example WebMarshal), you must exclude the following sites from inspection:
- https://login.microsoftonline.com
- https://graph.microsoft.com
This exclusion is to avoid issues with certificate validation.
You only need to exclude the specific requests made by the Entra connector. For example:
- Exclude the MailMarshal Array Manager IP address
- If authenticating as a user, exclude the specific user configured
