This was a major pain for us in upgrading to 2010. So many great things added yet something so fundamental was removed and caused us months and months of pain. People changed teams/departments or were hired and we had to write a program as part of the process so can automatically manage their teams groups. Not to mention the semi-open forum based groups that allowed people who belonged to certain teams/departments join and leave groups as they please. Way to really think that one through guys. Remove a feature that has been in place for 10 years or more and make companies who used it eat the cost of development. What exactly did you achieve by removing this anyway? I was so astonished when I discovered this new functionality last year that I actually opened a case with MS Premier Support services because I knew it had to be a bug. Microsoft has always evangelized the benefits of leveraging group based management. What could possibly have made you want to take such huge step backwards?
