I'm working with a client who is currently travelling in Germany. He's able to receive mail on his POP Telus mail account, however he is unable to SEND messages. Running Windows 10 Pro, Outlook 2013. This isn't the first time I've run in to this; another client had the same issue in Amsterdam. Any ideas why this would be?
First off, Telus' webmail is always a backup if all else fails.
I had problems when trying to connect to Telus' SMTP server when not on a Telus network, until I went into settings and made sure the SMTP port was 1025, 587 or 465. Depending on the port, SSL may need to be on or off. If I recall 1025 is SSL off and 587 is SSL on. I'm not sure about port 465.
