I'm trying to synchronize my mobile device using PDAsync and I get an error "MAPI login failed". What can I do?


This error occurs when one of two things has happened:

  1. The default mail program is Microsoft Outlook Express, Lotus Notes or Netscape Composer.

  2. PDAsync was installed before Microsoft Outlook.


Install Microsoft Outlook if necessary and configure as the default mail application:

  1. From the Windows Start menu, click Settings, and then Control Panel.

  2. Double-click Internet Options, and click the Program tab.

  3. Select Microsoft Outlook for the email, calandar and contact list.

If you continue to get the error, uninstall and reinstall PDAsync:

  1. From the Windows Start menu, go to Programs, and then PDAsync.

  2. Click Uninstall PDAsync and follow the prompts on your screen.

  3. Insert the PDAsync CD into your CD-ROM drive, and click Install PDAsync.

  4. Follow the prompts on your screen.

If you continue to get this error after reinstalling PDAsync, contact Technical Support to check for available upgrades or updates. Please provide your current PDAsync version number in your support request. To locate the version number, follow these steps:

  1. From the Windows Start menu, point to Programs, and then PDAsync.
