when ever I try to create a new appointement in outlook 2003 calender the system tells me "The form required to view this message cannot be displayed. Contact your administrator", However, if I have an exsiting appointement I can edit it without any problem and if I acess my clarendar from different PC I can create new appointement .
I'm connecting to Exchange server however it is not related to Administration since I got an other laptop and it working fine. I did many troubleshooting like repair Outlook, reistall it, Clear the forms cache , but didn't work.
I have tied already the following but didn't wok :
Option 1 Solution
Delete the Frmcache.dat from the location as stated below :
C:\Documents and Settings\user_profile\Local Settings\Application Data\Microsoft\FORMS
To Delete the Frmcache.dat File
Click Start , point to Find , and click Files or Folders .
Type Frmcache.dat in the Named box, and click Find Now .
Click to select the file and press DELETE to remove each instance of the file.
Option 2 Solution
Use the ForceFormReload registry key
When the forms cache seems to cause problems sporadically, and you cannot determine the cause of the problem, you can to set the ForceFormReload registry key in Outlook. When the ForceFormReload registry key is enabled, and Outlook encounters an error when opening an item that is based on a custom form, Outlook automatically clears the cache for this specific form.
Then, Outlook tries to open the item again. While this method does not correct the cause of the forms cache problem, this method does make the problem transparent to people who use custom forms.
To enable the ForceFormReload registry key functionality, follow these steps:
Start Registry Editor.
Click the following key in the registry:
On the Edit menu, click Add Value, and then add the following registry value
Value : ForceFormReload
Data Value : Reg_Dword
Value Data : 1
