I have successfully published a calender for someone who is on our network and have let someone who is external to my company have access to that. They have subscribed to the calender and added it to their own calender system. I was only able to give them read only access and I want to be able to give them the access to create calender appointments too.
Can you tell me if this is possible and if so, how I configure it?
Many thanks in advance.
PS. I am running Exchange 2010 SP3 RollUp 4
