Got an error authenticating the Office365 accounts via Basic Authentication.
- 2FA is probably turned on for the Office365 accounts.
- Some security policy from the email admin side doesn't allow basic authenticate for connecting the Office365 account to other software.
- Keep using the Basic authenticate. However, you will probably need to create an app password, and use that as the password to authenticate their Nylas account: https://developer.nylas.com/docs/the-basics/provider-guides/app-passwords/#microsoft
- Create an Azure app for your Nylas application, this will allow the Office365 accounts to use OAuth instead of Basic authentication. https://developer.nylas.com/docs/the-basics/provider-guides/microsoft/create-azure-app/
