We use Drop Box when we back up our Quickbooks files.

Lately when my Boss backs Quickbooks up, it creates a QBTempBackup.tmp in drop box, instead of the usual back up file. Of course I can not restore that backup to this computer with that. This is a new development and has only happened the last 2 times he has backed Quickbooks up.

When I back up to Drop Box, it creates the normal back up file, and he is able to restore fine on his end. 

We use Quickbooks Pro 2016

Any advice?

Thank you.
