Empty filter not allowed when filtering by an email address

Issue

When using Microsoft Dynamics NAV and filtering a Jet function based on an email address, the cell displays #VALUE! and the message "Empty filter not allowed" is displayed.

Cause

Email addresses contain the @ symbol.

Dynamics NAV reserves the @ symbol as a toggle between case (in)sensitivity.

It is not possible to filter on a field that contains an @ symbol when querying Dynamics NAV.
