Hi Everyone,
We recently migrated all our emails from a linux-based hosting service to Microsoft exchange online. I can say it has been more stable than the service we used before. One of the few issues we faced was that we cannot configure it in our reporting servers e.g. backup servers. The problem is that we have to specify a SMTP port for them to work while none of the following ports worked for us:
- 25 with no encryption
- 587 with TLS | Auto
Used “smtp.office365.com” as the outgoing server and "My outgoing server requires authentication" is also checked. When I configure it through outlook using IMAP protocol it says:
Send test e-mail message: None of the authentication methods supported by this client are supported by your server.
I would appreciate any help.
THANKS
