I really like the option to use Proton Mail Bridge to be able to get my Proton Mail account into Outlook.

However, the Bridge is lacking a bit when it comes to resistance against synchronization errors. I have had several instances when the message count is different between Outlook and the Proton Mail web app.

I need to be 100 % sure that what I see in Outlook matches what I see in the web app, and vice versa. Some sort of built-in folder/message comparing feature would be nice to have. I understand that the way things work with Bridge, there is a possibility for hiccups. What I would like is a feature that detects and remedies these hiccups.
