Calendar Error

I am receiving the following error message running Outlook 2003 with Office XP and Windows XP SP2 when trying to enter an appointment or meeting in my Calendar:

"The messaging interface has returned an unknown error.  If the problem persists, restart Outlook."

I have restarted Outlook to no avail.  I have searched Microsoft's site to no avail.  Can you help me?

Thanks,
Joseph Alford

Try recreating your Calendar -

If you have a lot of data in your calendar that you don't want to manually recreate, use the import/export wizard to export your calendar into a .pst file.

You cannot by default delete the Calendar through the Outlook client, but you should be able to through webmail -

After deleting the Calendar, empty your deleted items folder to completely remove it.

Rclick and choose new folder - name It Calendar and in the drop down box, make sure to have it say it contacins Calendar options

If you exported your data from your old Calendar, use the import/export wizard again to repopulate your calendar.

To madspire:

I don't have anything I care that much about in my calendar.  I tried to delete my calendar using Outlook Web Access and was unsuccessful.  Is that how you meant for me to delete my calendar?  In help is greatly appreciated.

I did mean through web access, but if it doesn't work... I'm not sure if that's a restricted setting by the Exchange admin or if it's just not possible in 2003 like it was in 2002. Unfortunately, I'm not in an environment at the moment where I can test this out -

There is a way you can delete the calendar through the comand prompt - This is good for every version of Outlook from 97 to 2002, but again, I haven't tried it on 2003.

If deleting and recreating the items that cannot be opened does not correct the problem, perform the following steps:

1. Back up all mailbox information by downloading messages to a PST. Personal Folders can be added to your profile by selecting Services from the Tools menu and choosing Add.  
2. In the Outlook client, select Import and Export from the File menu.  
3. Follow the Import and Export Wizard and select Export to a File.  
4. Select a file name and select Calendar as the file to Export from.  
5. Delete the Calendar folder; to do this, start an Exchange Client from the command line by typing exchng32. The calendar folder can be deleted from the Exchange Client because it is viewed as a standard folder and not a required Calendar folder.  
6. Recreate the Calendar folder by starting Outlook from the command line using Outlook /resetfolders.  
7. Move all messages back from the PST to the mailbox. From the File menu, choose Import and Export  


If this fails, you can always try the standard Detect and Repair feature of Outlook - with 2003 you will need access to the Office 2003 cd - if you run detect and repair without having the cd, you may not be able to open any Office program until you do have the cd.

To run Detect and Repair - from outlook, click on Help<Detect and Repair<check both options to restore shortcuts and discard customized settings.
Madspire,

I tried what you suggested.  But, I am unable to find the file exchng32 anywhere.  I have done a search on my local machine running Outlook 2003 Client and on our Exchange Server running Exchange Server 2003 Standard Edition.  Is this perhaps an Outlook 2002 or older?  Thanks for your suggestions but am still unable to add anything to my Calendar in Outlook 2003.

To all:

I have solved my problem.  I am running ShoreTel software that works in conjunction with Outlook 2003 and our new Voice over IP phone system.  One of the configuration questions says: "When posting to this Calendar, use ShoreTel".  This box was checked, evidently when the software was installed.  There are two other options: "Use IPM.Appointment" or "Use Forms".  I checked "Use IPM.Appointment" and now everything works fine.  I did not solve this, I stumbled on to the answer.  If anyone else encounters this problem using ShoreTel software, be sure to try this.
