This question already has an answer here:
After a lot of research and effort I have successfully made a connection to my Esri Personal Geodatabase (.mdb file).
Now I want to edit some attribute data in the attribute table of a layer... BUT I can't because the toggle edit and the editing toolbar is greyed out.
So how do I edit a layer inside (.mdb) file that I have loaded into QGIS?!
I am using QGIS 3.
Don't ask me why I want to do it this way. (But If you wan to know why, it's because I want to edit the (.mdb)file in QGIS and then send it to someone who is using ArcMap who should be able to read/write to the file too. The other person has ArcMap and I have QGIS).
