We have a customer with a lot of old access files that we are taking a look at. Honestly we don't deal with Access much but they are having performance issues with it so we decided to take a stab.
First thing I noticed is all the files are in Access 2002-2003 format and I wanted to try to see if we could get them upgraded to 2016. A lot of the mdb files are upgrading but a few won't.
We can open the problem mdb files and it works fine but when we try to Save As it just does nothing! You choose Save As (.accdb) and choose the folder, click Save and it does ABSOLUTELY NOTHING! No errors, no success at the bottom right and NO file is created at all. I've tested this on Access 2013 and 2016 with multiple computers so I'm thinking something in this mdb is causing it to not be able to save. Not cool that it doesn't give any errors or helpful notifications as to why it couldn't save. I have already tried a compact and repair database.
