Quick workaround for Gmail IMAP access issues without 2FA if you have Office 365

As mentioned in other issues (#1081, #1082) it is no longer possible to log in to Gmail via normal password.
One solution is to use app passwords but these require enabling 2-factor authentication.

Another one I found is to use Outlook.com as a IMAP-to-Gmail proxy. This requires any Office 365 license.

1. Add your other email accounts to Outlook.com
   • You don't need to open Outlook account, you can just sign in with any Microsoft account (including one created for *@gmail.com)
   • Once you do this, your Gmail account with show up as a folder named like your gmail login (including over IMAP)
2. Configure SMS Backup+ to use Outlook IMAP server - outlook.office365.com and your Microsoft account credentials
3. In backup settings update Gmail labels to be prefixed with the name of your account and /, e.g. you@gmail.com/SMS

That's it. It should work now. Outlook syncs emails back to Google with few minutes of delay so you may need to wait a bit for them to show up on Gmail side.

Closing as nothing to do here. This was informative only but this repo doesn't have discussions.

Disregard this advice. Microsoft had sunset this feature.
