Unable to add customer filter in Outlook Addin until added one on the Web
One to note.
I was unable to add a custom filter in the Outlook addin (I would add the title and query and click Add Filter which would take me to the task view. When I went back to the custom filter page it would be sitting unsaved. Repeated clicking on Add Filter wouldn't help).
I then went and added one with no problems using the Web interface. After that the Outlook addin now has no problems with adding custom filters.
Outlook 2010, Chrome, Win 7.
