Its the substandard conduits that come with the 650.
Hi - my issues were different than yours,but similar in that bottom line, my calendar data wasn't syncing correctly with Outlook. I've been dealing with this problem for the past 4 weeks. Sprint's technical support was useless, as was palmone.
For 5 years, I have successfully synced my Palm Smart phone to palm desktop at home, and outlook at work - (4 different phones, 4 different companies). It dawned on me - for the past 4 palm devices, I was provided Chapura conduits... The 650 didn't come with them... GUESS WHAT. I bought Chapura Professional XT and all the issues I was having (they were too copious and too weird to go into here) were solved, in one measly synchronization. ALL of them.
Don't wast ANY more of your time... Navigate over to Chapura's website and get one of the conduit programs -= trust me... You'll be glad you did.
