To Dos Crashes When Sorting Flagged Emails by Category

[Josh_D_Haskin]

    To Do crashes when I attempt to group my flagged emails by color coded categories. This issue has persisted through all platforms for the application, including browser and in app. I've tried clearing cache files and I've had co-workers test this on their computers as well, and they all receive the same white screen. I assume this is a bug that needs patching but do let me know if there is anything I can do in the meantime as I rely quite heavily on this feature for prioritizing my tasks.

@Josh_D_HaskinI have the same problem.  It's preventing me from making the switch from Outlook tasks because I categorise tasks based on various priorities.
