Prob setting appointments in Outlook

I am unable (all of a sudden) to set appointments in Outlook Calendar. I
keep getting the message: "Could not complete the operation. One or more
parameter values are not valid." I also get the same message when I try to
print the Calendar. Any clues as to why this would be happening? The only
thing I have done recently is uninstall my anti-virus software and switch my
internet provider.

The first thing I would try is to clean up my forms cache.

To do so, follow these steps: 1. On the Tools menu, click Options.
2. Click the Other tab, and then click Advanced Options.
3. Click Custom Forms.
4. Click Manage Forms.
5. Click Clear Cache.
6. Close all open windows, and then restart Outlook 2003.

If the above does not work, try the following.

Deleting the Forms Cache File:
The Frmcache.dat file is the primary file to delete. The Frmcache.dat
file serves as an index of the individual forms that have been cached
on the computer. Use the following steps to manually delete the
Frmcache.dat file. In addition, these steps delete all of the cached
forms on your computer, which are stored in subfolders of the
Forms folder.

1.. Quit Outlook.
2.. Search the Hard drive (<F3>) to locate the Frmcache.dat file.
(Be sure to check in HIDDEN files on W2K or WXP.)
3.. Delete all that are found from the FIND window.
4.. Open Outlook.

When you restart Outlook, and use a custom form, the forms cache
is re-created. Until a custom form is used, Outlook does not re-create
the Frmcache.dat file.
