[ms office - 2019] Access compatibility with 365

[Chrish5]

So we have Office Pro Plus 2019 installed on domain computers and staff and students can install Office 365 at Home.

We have students that are making Access files at home on 365 but they can't open them in school. Access says

"The database you are trying to open requires a newer version of Microsoft Access"

I've checked Office updates and it tells me that the workstation is up to date (Version 1808 (Build 10378.20029 Click-to-Run).

The file is an accdb file which 2019 should be able to open and we have at least 6 students with the same issue with different files.

On a workstation that has Office 365 installed (using a staff members license) the file will open ok.

 

Any ideas what's going wrong? Should 2019 be able to open the files from 365? Should I be installing 365 throughout? Do I need to add something to allow 2019 to open the files? Do the students to do something to their files before trying to open them in school?
