If you're working with a database created in a previous version of Access, you can convert it to the 2007/2016 file format to take advantage of the new features. You can also convert from the Access 2016 format to older versions of Access.
- File tab.
An Access 2016 file (.accdb) can only be opened in Access 2007/2016 and not earlier versions of Access so make sure everyone who uses the file is running the correct version before you convert it.
- Save As.
- Not all Access 2016 files can be converted to an earlier format. If the database contains new 2016 features such as attachments, multi-valued fields, offline data, or links to some external files, Access may not be able to convert the file.
- Click the Save As button.
If you have any open database objects, you'll see a message telling you to close them. Click Yes. If Access is unable to convert the file, you'll also see that message at this point.
A copy of the database is made and opens, while the original database is closed.
