Yes,
so first I created a M365 user with the email address that I am interested to use as a default sending email in ERPNext. Then I created a user with the same email address in ERPNext. On logging in as this user I went to the conneted app and used the Connect to M365 (name of app). It asked me to log into the M365 account, I successfully logged into the account.
Then I created the email address for the same user but it gives the above error.
Try creating Email Domain and inherit from it into Email Account.
Thanks for this in-depth tutorial! It sums up perfectly what I found out by searching multiple threads and issues. The official documentation on this topic is basically useless or not existing! Maybe we can extend it a little further and place it in the official frappe docs?
Anyways, I still have issues with the integration of emails with Office365 and ERPnext/frappe.
We use the Security Defaults provided by Microsoft, which state to “Block legacy authentication methods, such as SMTP Auth”… see: https://learn.microsoft.com/en-us/azure/active-directory/fundamentals/concept-fundamentals-security-defaults#block-legacy-authentication-protocols
Did anybody get the email sending to work with Security Defaults enabled? Or am I required to use a Mail Connector for sending? see https://learn.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365#option-3-configure-a-connector-to-send-mail-using-microsoft-365-or-office-365-smtp-relay
Thanks!
Is it this step discussed here? [Tutorial] Connecting Frappe/ERPNext to Microsoft 365 mail services OAuth - #4 by rmeyer
Hi:
I was able to sending through SMTP even without OAuth … it’s still working disabling Security Defaults and probably it will works for a long time …)
Also is possible to activate/deactivate SMTPAuth on certain accounts (via Powershell)
Anyway … STMPAuth isn’t needed since OAuth was implemented …
Hope this helps.
Nope, that was not the issue.
I created a new connected app and now its working.
I followed the tutorial step by step. Maybe i missed something in the first run.
Great tutorial. Please move it over to the official docs for Connected Apps in Frappe
@avc I follow all your steps and my incoming email is working completely fine but when I enable outgoing I am getting this error I can’t find where it was gone wrong
Hi:
Check the permissions of your M365 user.
Can use SMTP?
Hope this helps.
I did OAuth for Office 365 and after It didn’t required to enable or disable SMTP AUTH but when I enable outgoing i got this error
Hi:
Have you checked this?
But for that I need to disable security defaults that is not possible.
and it’s mandatory to enable SMTP AUTH ?
Hi:
You can enable SMTP AUTH for specific mailbox
First of all: Thanks for the straight forward turorial!
I followed the guide but I’m still receiving an error when I try to enable Outgoing Mails.
On saving the Email Account I receive the following error message:
Here the Traceback:
Traceback (most recent call last):
File "apps/frappe/frappe/email/smtp.py", line 111, in session

raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (451, b'4.7.0 Temporary server error. Please try again later. PRX5
Do you have any ideas what might be the cause of that error?
I’ve never faced this error, but …
Take a look here.
@avc Thanks for the hint. It worked out to authenticate with a user that has only the role “Global Admin”.
I now receive the error 535 5.7.3 Authentication unsuccessful while trying to enable outgoing email for a shared mailbox.

UPDATE:
This error could be resolved by following the procedure described by @rmeyer in [Tutorial] Connecting Frappe/ERPNext to Microsoft 365 mail services OAuth - #6 by rmeyer
Yes, SMTP is enabled for single mailboxes as decribed earlier in this post.
Thanks for your help. Now it is working as expected. 
Hi @avc,
thanks for the tutorial. It took some time to get it working, but now i can send E-Mails via MS365 and oauth. But it only works for personal accounts. I would like to additionally add an account like jobs@example.org and allow several users to send via this e-mail. I created a new user for jobs@ and authorized this email for this user. But other users can’t see this email-account. With smtp and basic-auth this was possible.
Can anyone give me a hint how to setup e-mail accounts with oath for shared mailboxes/emails?
Regards
Kevin
Hi @mindcry:
I think it’s related to “Send on behalf” permission
Check this, please:
Hope this helps.
