O365 sites... do you let your users create groups?

[Oaktech]

Exactly as the title says.

 

Our users have been able to create and administer groups up until now, but I've just looked discovered that they have been doing it left right and centre and that we've got a load of groups which are essentially duplicates of each other set up by different people to do the same job and are now a mess.

 

It's come to my attention because people have been getting emails that aren't intended for them and also not getting things they were expecting because some people have updated groups they own and some people haven't.

 

I've had what might be a knee jerk - stop doing my job for me - reaction and removed the ability to do it.

 

Am I over reacting?

 

I don't think I am given the horlicks they've made of it left on their own. What do you guys do?
