A family of Microsoft relational database management systems designed for ease of use.
I have been having similar issues in that I cannot compact and repair any access database on a local drive. I've tried reinstalling office 365 which has made no difference, I have not tried reverting to an earlier version of office 365. I tried creating a new database and imported everything, but the problem persists.
This is happening on two Dell Windows 11 computers, Office 365 and windows are fully up to date.
Interestingly I use a synology disk station for the back ends and if I copy the front end database from the local drive to the synology drive, compact and repair works perfectly. This will help for now, but its a real nuisance!
