Have you looked what Microsoft says? As the provider, they should know which settings are required. Alternatively, maybe you can find settings for other 3d party mail clients like Thunderbird and try those.

Daniel van Rooijen, Thanks a lot for your valuable time in replying to my message. I did, and I copied the server settings as Microsoft mentioned and tried Thunderbird to confirm, besides the Outlook client, but I am afraid that it is not working. I tried changing port number but neither 465 nor 587 and setting, but no luck so far.
Side note away from the topic: I do not know why, but I feel that I am a geek when I am using the bat!
