In Office 2007 (and earlier versions), I had a few views to help me search for specific contacts. Specifically, I had one that sorted on Last Name and one that Sorted on Company Name with a filter for contacts where the Company was not empty.
The sort on Last Name works fine.
If I try and Filter on Company Name using Is Not Empty or Is Empty, it does not show any results - I sometimes get an Operation Failed message. I can filter on parts of the Company Name.
Update: It works fine in Caching mode. In Online / Live mode, it does not.
Any Ideas ?
