Microsoft Outlook email - Calendar Appointment Not Opening

Milly is right. It is most helpful if you include the version of
Outlook that you are working with and any relevent info like,
I just updated or I did nothing and all of a sudden...
I am including the most common cause for your issue.

First thing I would do is to clean up the 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 form, the forms cache
is re-created.

Let us know if this is not your solution.
