My "team" calendar grouping has disappeared from my calendar view. I am on Exchange 2010 using Outlook 2010. This "Team" group was automatically created and automatically updated with those who share the same manager as myself.
I unfortunately suspect this is related to my team now including more than 100 members and Outlook not supporting this, as a colleague has the same problem.
Assuming this is not a bug in Outlook, how can I restore the team calendar grouping?
