We recently upgraded from exchange 5.5 to 2k and during the period we were
using 5.5, everyone in my organization were able to share and view each
others calendar. Now with exchange 2k, that is no longer the case. On the
outlook client end Ive tried changing permissions and I get an error that
the client operation failed. Are there permissions on the server end that I
need to change globally? on the client end? Why did it all of a sudden
change after we upgraded?
