After furious head scratching, lid asked:

| I keep getting an error popping up while Outlook 2002
| (10.2627.3501)SP-1
| is running.
| "unable to update public free/busy data"
| This is running on a Dell Optiplex gx270 for the last 2.5 years, with
| no problems until recently. Probably due to some piece of software
| installed. Anyone have ideas how I can stop this error from randomly
| coming up each day??
| I did find a patch for the registry, but it did not work.
|
| I am not communicating with Exchange server at all.
|
| Thanks for any help.
