Hi after the upgrade on a SG135 UTM Outlook Web access stopped working.
Ther Exchange server is part of SBS 2003. after the upgrade we get this message
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /exchange.
Reason: Error reading from remote server

I know its a pretty old server and we are in the process of upgrading to 2016, but meanwhile everyone stopped to get email on their mobiles and tablets.
This just happend after the upgrade.
Thanks in advance
Paulo
