Thank you!
I have two Onedrive accounts with exactly the same ID (email address), a personal and a work account. They look the same when looking into the Enpass sync-setup page.
I did not know that Enpas has a dependency to the account logged in on the browser. That explains why Enpass did not ask for account & credentials when I removed and then reconnected the syncing.
I found the Laptop's Enpass app folder in the picture folder on the "wrong" account - of all places, That explains why I did not see any Enpass folder initiially.
In summary, I logged out in the browser and was able to setup the sync as I want.
But now I wonder whether I can use Enpass and sync passwords while being/if I log in to the other Onedrive on the browser.
Regards
Torbjörn
