To reproduce, open Customize View in Task window. Choose "Group By..." and choose any field for grouping. When leaving the Customize View dialog, Outlook shows the following error:
"The sorting or group by operation failed. Either these folders do not support sorting or the conditions are too complex. Sorting and group by settings have been reset."
This same procedure works with non-Scalix connector profiles. Can anyone else confirm, and if so, is there any hope of this getting fixed?
