Welcome to the community! Don’t know exactly if KoBoToolbox can be connected with
MS Access. Looking at the discussion that has happened in the past (it seems impossible):
But we do have support articles on how KoBoToolbox can be linked with MS Excel and Power Bi. Maybe these support article should provide you some hints if it’s possible to connect.
Kindly please do share your findings with the community (if you are able to share) as a large number of users should be benefited from your findings.
Have a great day!
