My Outlook 2003 has all of the sudden decided that it will not allow me to
add new contacts or appointments. When I get everything typed, then hit
Save- I get a message saying that operation can not be completed- parameter
values not valid. I have no idea what that means. I am not a techie- help.
This was working fine until about a month ago. Please help me- thanks
