Hmm. Are you sure it's 2003? You can check the version by going to the "Help" menu and click the "About" button down at the bottom. It's important for the version to be correct.Ok, sorry. Blackberry is 7100t, outlook is 2003 I believe, Treo is 700p. Blackberry stopped synching after I updated outlook. I just went to "help" on the toolbar and there was a choice of search for updates. I didn't know it would replace everything!
Do you regularly update your Outlook or this is the first time you have tried it?
Can the Treo sync to Outlook?
