Sending Emails Fails about oauth2ms HOT 4 CLOSED

I copied the code recommended in steps.org and added my smtp server details. When I try to send an email in emacs I am prompted for my password (rightly or wrongly, I was expecting to not be prompted, so I just hit return).

Yeah, the smtp library always asks for the username and password, irrespective of the type of authentication it is going to use. For now I too hit enter twice (will need to investigate if we can disable that). The 250-AUTH LOGIN XOAUTH2 line in the log shows that it is using OAUTH2 for authentication.

451 4.7.0 Temporary server error. Please try again later. PRX4 [server.prod.outlook.com]

I have never faced this issue before but looking at the SMTP rfc: https://tools.ietf.org/html/rfc5321, it looks like it is an error with the smtp server and not with the client. Unfortunately, there isn't much information available on this.
I found a page which explains that this is due to incorrect smtp configuration on the server. Also make sure that STMP is enabled on your server. This link has more details on how to check.

Hope this helps. Sorry if this isn't very helpful.

Thanks for your reply. I'll chase down those possible solutions. If I find anything noteworthy I will report back, but since this is most likely not a client issue, I am closing. Again, thanks for the package!

I can confirm (for my issue at least) the fix you linked to above - described here worked for me.
