    • Recreate the Outlook user profile

    To prepare for the above changes perform the following steps:

    1. Create a .PST file
    2. Move the following data from the original Outlook file (OST or PST file) to the new PST file (CRM records have a CRM icon vs an Outlook icon; see section 2.3 – step #4 for an example):
      • CRM contacts
      • CRM tasks
      • CRM appointments
    3. Reconfigure CRM for Outlook or uninstall/reinstall CRM for Outlook.  The CRM data will not re-sync with Outlook. Remember to apply the latest update rollup if you reinstall CRM for Outlook
    4. When finished you can archive (or delete) the PST file created in step 1
