Hi,
Which type of email account are you using?
Once we add a contact to Favorites, that contact is saved in two locations:
{06967759-274D-40B2-A3EB-D7F9E73727D7}
Container Class:IPF.Contact.MOC.QuickContacts
{A9E2BC46-B3A0-4243-B315-60D991004455}
Container Class:IPF.Contact.MOC.ImContactList
We may try to use the MFCMAPI tool to delete these properties and then test the issue again. To do this, please follow the steps below:
1. If you are using Exchange account, please first turn off Cached Exchange mode.
2. Download MFCMAPI tool from:
http://mfcmapi.codeplex.com/
3. Launch MFCMAPI tool.
4. Click Sessions > Logon > Choose your Outlook profile.
5. Double click on your SMTP address.
6. Expand Root Container> Top of Information store > Contacts.
7. Right-click on the GUID mentioned above and select Delete.
8. Restart Outlook and test the issue again.
Please let me know the result.
Regards,
Steve Fan
