SMTP Port is not working in office 365. Though it worked in Gmail by using app password, it's not working on office 365.

Thanks in advance for any help.
I can share your frustration because your setup should in theory just work. I had the same configuration from 3.xxx to 4.2 and office365/Exchange Online emails worked flawlessly. Once I installed 4.3, the setup worked up to a point and then finally had a certificate error out of no where which everyone else has been complaining about.
As my nop website is hosted in Azure (I assume exchange online is too), I had set SSL unchecked and had no problems ever since. I haven't had time to investigate why, if its really a nopcommerce mailkit issue or some sort of environment amendments in Azure.
I do know Azure had notified of TLS certificate changes but I don't know if this impacts nop.
