Error messages starting outlook 2007

My question is about Communicator, but I'm not sure if I can get help here.
I installed Communicator 2007 trial in XP Pro, just the trial, then
uninstalled it after it would not work with a hosted exchange account. Upon
uninstall, now my installation of Outlook gives me error messages and I can't
get rid of them. Several error messages pop up whe Outlook 2007 starts on my
XP machine. All of the error messages indicate that The Form Region
"IPM.Note.Microsoft.Conversation.Region cannot be opened." The form region
manifest specifies and add-in that is not installed. The Form Region
"IPM.Note.Microsoft.Conversation.Voice.Region cannot be opened." The form
region manifest specifies and add-in that is not installed. The Form Region
"IPM.Note.Microsoft.Missed.Region cannot be opened." The form region manifest
specifies and add-in that is not installed. The Form Region
"IPM.Note.Microsoft.Missed.Voice.Region cannot be opened." The form region
manifest specifies and add-in that is not installed.

Does anyone know how to fix this. If I do a detect and repair, I still have
the problem. Outlook still works, but this is annoying on startup. Thanks
for your help
