Redmine

The settings below worked for me.

production:
    email_delivery:
    smtp_settings:
      address: smtp.office365.com
      port: 587
      domain: smtp.office365.com
      authentication: :login
      user_name: myuser@mydomain.com
      password: mypassword
      enable_starttls_auto: true

These setting worked for me too, thanks a lot!

I can confirm, that today (July 2020) the settings from Bonnie O from 2013 are still working.

I can't for the life of me make this work.
No matter what options I select I always get an error, I think that the closest setting I can get I still get an authentication error:

An error occurred while sending mail (535 5.7.3 Authentication unsuccessful [LO2P123CA0098.GBRP123.PROD.OUTLOOK.COM] )

I tried many different options and followed many different online forums and instructions but none work, I'm starting to wonder if this is due to the 2FA on my account and if there's a way to go around it somehow.
My settings are as follows:

production:
email_delivery:
delivery_method: :smtp
smtp_settings:
address: smtp.office365.com
port: 587
domain: smtp.office365.com
authentication: :login
user_name: admin@mydomain.com
password: mypass
enable_starttls_auto: true
openssl_verify_mode: none

Please help.

Hi

It work fine by me

Thanks

Just trying to get help again here, this is still not ok for me.
I've tried with and without quotation marks in everything, disabled the 2FA in this account and it's still unsuccessful.
Is there any other factor that may be causing this?
I have the exact same spacing as Bonnie O and lines (with the exception of username and pass).
Is there any way I can try to establish the connection manually to see in which step it fails? something that provides a more detailed fault information?

My gmail configuration works perfectly fine with the official redmine instructions, why is office365 not working with those?

For future users, these settings are working correctly but your account needs to allow external SMTP access:

Hi,

i have the same problem here and it still not working.
I have tried the configurations that are mentioned above and also activated the external SMTP access for the specific account. Also configured the action_mailer.perform_deliveries to true.

The message that i get is always "execution expired". No authentication error or something else.

Did i miss something? Should be 2FA disabled?

Yes, I have fought with this issue as well and it's now solved.
Create a dedicated email just for this so you can disable 2FA and follow the links I provided so that this email allows access from "unsafe applications" and it will work.
It's better that you limit this account for redmine only as you will disable all safety features basically.
