Question

Is Teltonica still not using TLS?

I cannot get the Teltonika RUT240 to check Office365 email account with POP for the SMS Gateway and other email functions.

The business only uses Office365 which only accepts a late version of TLS. Older SSL protocols aren't an option.

There is also no IMAP option.

I've tried access with a password, with and without MFA

Tried with an "app password"

There isn't a single forum post referring to Office365... which is very strange!

Answer 1

SMS gateway works just fine with RUT240 router and outlook account for me, using latest RUT240 FW version:

Make sure you set correct POP settings on the router:

POP server name outlook.office365.com

POP port 995

Also check whether you enabled POP3 on your outlook account:
