I am struggling with setting Email tool trying to use my business e-mail which is working in Office 365.
Can anyone provide the correct settings for it?
Couldn't it be because of the company security settings?
I tried also STARTTLS with 587 port.
afaik this has to do with the Office 365 settings respectively if O365 allows 3rd party services to access their SMTP server > https://docs.microsoft.com/en-gb/Exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-dev...
For option (1) according to this setup SMTP client submission is required (which I think, we do not support) and for option (2) or (3) you might need admin access as DNS changes are required.
Is it allowed in your company to send emails through SMTP and/or do you have other tools who successfully are able to send emails?
Did someone solve this so far?
PS: you can as well write directly to firstname.lastname@example.org to request help and see if there is an entry in their knowledge base.
