Quick and easy question (I have Googled but can't find the specific answer).

Can Access 2019 modify and save a database application in Access 2016 format - so it can still be opened in Access 2016 and before without the 'The database you are trying to open requires a newer version of Access' error?

The format is identical in A2007 or later.
The issue is when you use a feature not supported in an earlier version.
For example enabling bigint support will trigger that message.
Using modern charts won't trigger a message but there is a blank space where the chart should be

Short answer is Yes. That said, the golden rule still applies: always use the oldest version of Access that will be used to run the database for all development to ensure compatibility. Also, using Late Binding will avoid any potential reference versioning issues.
