Glad you got it resolved! Hopefully you won't need to, but the best way of reporting issues is covered in github.com/phw198/Outlo...

The older version will get replaced yes, but you can always uninstall and go back to a previous version - they're all available under github.com/phw198/Outlo...
Might be worth taking a backup of your settings.xml file first to make rollback easier if you need.

Fantastic! Really pleased Stripe worked - I've spent the last few days setting that up and you're the first to try it out 🥇

Have you come across phw198.github.io/OutlookGoogl...? I developed this open source project for over a decade now for the exact reason you describe...

Thanks for asking! PayPal should let you pay in USD (though it does charges a poor foreign exchange rate), but I can only receive donations in the one currency of GBP.
OGCS has an option to start the application on system startup - have you tried that?

A Google bug surfaced on 23-May that may cause OGCS to keep attempting deletion of a non-existant "ghost" item, or fail to sync a copy of it.
A workaround has been released that will stop this behaviour - please apply the hotfix if affected: github.com/phw198/Outlo...

Meanwhile, the next alpha release should be coming through shortly...

Finally got the new code signing certificate, courtesy of www.certum.eu by Asseco!

This time it's a "standard" certificate which can be renewed each year, so unlike previous years, its reputation won't be lost every 12 months...and install experiences should be cleaner ☺️
