I have an Outlook Exchnage account from 1and1 and i use Outlook 2007 on my PC. I have given permissions in the account and on the calendar but when i try to share the calendar with my wife (who also has an outlook exchange account) it come up with the message:
"Calendar sharing is not available with the following entries because of permission settings on your network."
Running XP SP3, Office 2007.
Not sure if this is a client issue or a 1and1 service issue?
