No synchronization when Outlook express is default mail program

·You import mail from Outlook into Outlook Express, but you removed Outlook from your computer before you tried to import the mail into Outlook Express.
·You configure Outlook Express to be the default Simple Messaging application programming interface (MAPI) client.
·You import or export mail from Outlook Express, and you do not have Outlook installed on your computer.
To resolve this issue, try one of the following methods, as appropriate for your situation.

Method 1: If you want to use a special program you can use Outlook Express Fix Toolbox

Method 2: Change your MAPI Settings

Configure Outlook Express to not be the default Simple MAPI client before you import the mail items. To do this, follow these steps:
1.Restart your computer, and then start Outlook Express.
2.On theToolsmenu, clickOptions.
3.On theConnectiontab, clickChangeto open theInternet Propertiesdialog box.
4.On theProgramstab, click an e-mail application other than Outlook Express in theE-maillist. ClickApply, and then clickOK.
5.ClickOKagain to close theOptionsdialog box.

You can now import or export messages.

To make Outlook Express Your Default Windows Email Program :
1.Make sure Outlook Express is not running.
2.Select Run... from the Start menu.
3.Type "msimn /reg" (excluding the quotation marks).
4.Hit Enter.Wait for, say, ten seconds for the process to finish. Nothing will appear on screen. Do not let that disturb you.
5.Launch Outlook Express.
6.Select Tools ' Options... from the menu.
7.Go to the General tab.
8.Click Make Default under Default Messaging Programs.Click OK

I dunno but you might be better off just copying the outlook express data files from one computer to the next instead of trying to export.

1. Step 1 Install the Palm Tungsten software. This software is required in order to sync Palm Tungsten with Outlook Express. To install the software, place the CD-ROM in your PC and follow the on screen instructions.
   
2. Step 2 Use the HotSync cable included with your Palm to plug into the USB port of your PC. You will then plug the other end of the cable into your Palm Tungsten.
   
3. Step 3 Open the HotSync Manager program on your PC through the "Start" menu or clicking on the icon. You can manage the different programs available for synchronization through this program. Select Microsoft Outlook as one of the applications that you want synched onto your Palm Tungsten.
   
4. Step 4 Turn on the Palm Tungsten. You will see a star icon on the menu of your PDA. Tap this star with your stylus to start syncing Microsoft Outlook Express. A dialog box will appear on your PC during the process to know the progress of the synchronization.
   
5. Step 5 Unplug the cable from your PC and Palm Tungsten once the sync is completed. As the Palm resets, you will now notice that Microsoft Outlook Express is available on the PDA.
   

Outlook Express - no software included with Palm devices but There is third-party software to synchronize the email and Windows Address Book from Outlook Express to Palm OS devices. Here is a relevant link: http://www.livepim.com/expressmirror/index.htm - address book conduit to mirror the OE address book to Palm Desktop

Try to change conduits to hotsync with PDS, if it will work then the problem is with the MSOutlook.

This is how I got it working. Don't use wireless sync software, someting is definitely buggy with it. Here is what I did to resolve sync errors: 1. Perform a hard reset on the Palm 2. Go to the Palmone folder on your hard drive (C:\Program Files|PalmOne. Look for the Backup folder. Rename this folder Backup Old. 3. Connect the Treo to your computer. 4. Right click the Hotsync icon in the taskbar and click Custom. Change the four Outlook conduits (Calendar, Contacts,Tasks,Memos) to Desktop overwrites Handheld. 5. Run a Hotsync with the Treo. It should sync without errors. If you need to install additional applications you can add them now

I was ready to give up completely. Uninstalled, reinstalled, nothing worked. Here is what I did to resolve sync errors: 1. Perform a hard reset on the Palm 2. Go to the Palmone folder on your hard drive (C:\Program Files|PalmOne. Look for the Backup folder. Rename this folder Backup Old. 3. Connect the Treo to your computer. 4. Right click the Hotsync icon in the taskbar and click Custom. Change the four Outlook conduits (Calendar, Contacts,Tasks,Memos) to Desktop overwrites Handheld. 5. Run a Hotsync with the Treo. It should sync without errors. If you need to install additional applications you can add them now. This worked for me. I hope it helps with your errors.

Generally this error means that HotSync manager (via the 4 Outlook conduits) is having a hard time connecting to your Outlook or, in some cases, specifically to your Oultook profile.

This is what I did to fix that error:

Hard-reset your Palm to erase all data (that usually involves pushing the small "reset" button on the back, then pressing the "power on" button until the device boots, and then pressing "up" to confirm the hard-reset)


After that, sync your palm. The sync software will ask if you want to use your existing profile or create a new one. Create a new one. Then the program will offer to sync your Outlook profile with your Palm. Click on "ok", and a message asking you to accept to sync your Outlook data with more than one profile will pop-up. Click on OK, again... and that's it!
