Does anyone use ManageEngine ServiceDesk Plus for supporting users and have you had success configuring it to send mail successfully? It's not rocket science to enter smtp info so it is either an issue with 365 not liking the way the app sends or maybe it's an oversight on my part in a mail setting somewhere in 365.
The settings don't get any easier to enter:
Server name: smtp.office365.com
Encryption method: STARTTLS
