This question may have already been answered but I wanted to explain our situation to better confirm. We have two companies, one company is already on an exchange server and we want to incorporate microsoft exchange with the other company but the execs want to be able to only have one calendar to share between them, it is sounding like this is not possible and they would have to have two different calendars???
What is the best option for us to use to have an exchange between two different sectors? Is there another way that might be better, easier for us to share calendars documents etc?
