For account administrators.



Click the icon in the top-left corner with three lines. Expand 'Users' and click 'Active Users'.

Click the username who you want to permit to send emails through Retreat Manager. Once the user is selected click 'Mail' in the pop-out on the right. Then click 'Manage email apps'.

Click all of the boxes. Then click Save Changes button at the bottom.


You must also disable security defaults in Microsoft Entra ID https://learn.microsoft.com/en-us/entra/fundamentals/security-defaults


The security defaults in Microsoft Entra ID block access through SMTP. Per the instructions at the above link:

  • Browse to Identity> Overview > Properties.

  • Select Manage security defaults.

  • Set Security defaults to Enabled.

  • Select Save.


For users trying to send emails.



Click 'Add sign-in method'

Select 'App password' from the drop down.

You can name the app password whatever you like, e.g. 'Retreat Manager'

Click Next and the next page will have a long, randomly generated, password which you can copy and use in Retreat Manager.
