  1. Hi Mohana. I've tried to do so but NAV gives me the following error: "unable to read data from the transport connection: net_io_connection closed". Any clue?

    1. Please make sure that whatever account you are using as the User ID and Password for this it actually has an O365 license attached. NAV first checks the credentials, then the port. In my case port 587 was active as an endpoint - but - I did not have a license for that admin@ user on my tenant. Added one of teh licenses to this user and problem is fixed! Thanks Microsoft for not documenting this! :)

  2. All the mails sended from Nav are reported as spam from my demo tenant (Remote Server returned '550 5.7.501 Access denied, spam abuse detected), when send outside the domain.

    I'm asking MS for this point.
