I currently have the Desktop manager set up to Sync by Tour with Outlook 2003 calendar Two Ways AND Transfer items within a range of days = 9999, 9999
This puts over 7,000 appts. on my phone!
I don't mind my blackberry not having all my past appointments but I do not want it to delete my old appointments in Outlook.
In my BB I also set it up to keep my appts. forever.
