I get the error message "Outlook contact folder is not selected or invalid!" since two days ago.
I don't know if it has to do with ne trying the new Outlook instead of Classic.
I’m maintaining an unofficial fork of GO Contact Sync Mod because the upstream project appears inactive.
This may be related to issues I’ve worked on around profile/folder persistence and Outlook startup/readiness handling. I can’t promise it fixes every “Outlook contact folder is not selected or invalid” case, but it may be worth testing if the problem is coming from folder selection not being restored reliably.
It’s an unofficial fork, so please back up first and test carefully. If you do try it, I’d be interested to know whether it improves the folder-selection problem.
