Outlook Calendar -- Stopped letting me enter Appointments!!! (everything else works...)

Suddenly Outlook has stopped letting me enter appointments or edit existing appointments.  I click the New Appointment button and nothing happens.  I click on an existing appointment in the calendar and it won't pull up the edit screen to edit that appointment.

Contacts work fine

Email works fine.

What gives?  Please help, this is killing me.

Greetings, searcherguy !

1. Reset the Outlook toolbar template. With Outlook close, do a search for and rename outcmd.dat file. Restart Outlook and a fresh outcmd.dat file will be recreated.

2. Register an important Outlook file. Go to Start > Run and type regsvr32 OLE32.DLL

3. Disable Outlook Addins.  Go to Tools > Options > Other > Advanced Options > Addin Manager or COMM/Addins and disable the addins.

4. Start Outlook in Safe Mode.  Go to Start > Run and type

"c:\Program Files\Microsoft Office\Office\Outlook.exe" /safe

Your path to Outlook.exe may be a little different.

5. Create a new Outlook profile.

6. Repair Outlook. With Outlook open, go to Help > Detect and Repair.

7. If no joy, reinstall Outlook.  Go to Add/Remove Programs and highlight Microsoft Office. Click on Install/Uninstall.  A menu will pop allowing you to choose repair or reinstall.


Best wishes!

Okay but I use Plaxo.  Will taking the above steps damage my Plaxo installation?  (Plaxo is an add-in that synchronizes Outlook with Plaxo servers to keep contacts up to date.)

Note by the way that I have been using Plaxo for a long time with no previous problems with the calendar, so the calendar is probably not caused by Plaxo.  

Also, I see that I am to "disable outlook add-ins" so I am guessing this will protect Plaxo, an Outlook Add-in.

Will the above steps affect my .pst file?  Should I back up my .pst file?

If you do not disable Plaxo addin, then Outlook will continue to work with Plaxo.  My concern is that there was a recent Plaxo update, which caused the problem with Outlook.  
The above steps should not affect your PST.  But you should always backup your PST file anyway.
searcherguy, any update?
