That’s why I asked details. As you correctly understand that “Collect data via Email” needs a single table if you want to update data. To make this happen, you have to think in such a way that your multi tables convert or resemble into a single table. The means are use of some action queries such as Make table. Also, you may need to use Update query or statement, delete query etc.
So it might be helpful to think in this direction if you do not have other option for data collection by email.
I am also very new to access but used this feature with experimentation, but I have not used any other methods.
