The error Unable to Authorize Microsoft/Office365 account may occur when an account has an issue with the connected mailbox.


Users may be trying to connect an account without a connected mailbox. This may occur because of a missing email address. 


- Visit the Graph Explorer webpage.

- Log in with the user credentials.

- Get the profile details by clicking on the `Get my profile`  tab.

- Confirm a value exists for mail field in the response.

- Confirm that the email address is the same email address they are using to log in.




Nylas only supports accounts without a mailbox using Virtual Calendars.
