QB 2016+ & MS Office 2010-

Issue:  QB and MS Office are not compatible with each other.  QB is unable to send via Outlook.

Resolution:  Install the “Microsoft Access Database Engine” for the version of Office you have.  Restart the computer and QB and Office should now be able to talk to each other.

Intuit Back-Up:

Issue:  QB data protect not backing up data. “Unable to backup data.  Data file is open by another user”

Resolution:  Set the QB IBuEngHost.exe service to run as system / administrator.  Verify its running under that account by looking in Task Manager.
