We added this mode to ensure all Mailbutler users can use our features, even if their email account configuration doesn’t allow the connection. Thus, all mail accounts can use Compatibility Mode. POP email accounts aren’t compatible with Mailbutler and will have Compatibility Mode enabled by default.
Please note that Mail must be open at the scheduled date and time.
How to activate/deactivate Compatibility Mode
1. Open Apple Mail.
2. Click on Mail at the top left of your screen.
3. Open Preferences…
4. Click on the Mailbutler tab.
5. Open Compatibility Settings…
6. Activate Compatibility Mode for unsupported email servers.
