One of my users has Office 2003 and for some reason under "My Calendar" there are two Calendars displayed namely Calendar (pst) and Calendar in Mailbox - Username. Is there some reason for these two appearing. I have tried to delete the first one (the pst calendar) but it will not allow me. Alternatively is there anyway that I can get the mailbox calendar to auomaticaly open on default rather than the other Your help is appreciated.... Andrew
