After you successfully import a public folder from Microsoft Exchange Server in Microsoft Office Access 2003, you may not be able to import a Microsoft Exchange public folder again. You may also notice that the name of the Public Folders folder in the Import Exchange/Outlook Wizard dialog box appears as Microsoft Exchange Server.

When you try to expand the Public Folders folder that appears as Microsoft Exchange Server, you may receive the following error message:This problem may also occur when you try to import any other Exchange folder or Microsoft Outlook folder.

Note You may notice this behavior when you select the Cached Exchange mode option for Exchange Server when you configure a mail profile.

To work around this problem, import the Microsoft Exchange public folder by using an online Microsoft Outlook profile that does not run in Cached Exchange mode. If your Microsoft Outlook profile runs in Cached Exchange mode, create a new Microsoft Outlook profile that does not run in Cached Exchange mode and then use the new online Microsoft Outlook profile to import the Microsoft Exchange public folder.

You can also work around this problem by closing and by reopening Access 2003 when you experience the problem that is mentioned in the "Symptoms" section. When you import a Microsoft Exchange public folder by using a Microsoft Outlook profile that is running in Cached Exchange mode, the Microsoft Exchange public folder may be imported successfully one time in every mail session. Therefore, if you restart Access 2003, the problem may be resolved.

When your Microsoft Outlook profile is running in Cached Exchange mode, you can create an additional Microsoft Outlook profile on your computer that does not run in Cached Exchanged mode and is online. You can use the additional online Microsoft Outlook profile for purposes such as importing a Microsoft Exchange public folder.

However, the disadvantage of having multiple Microsoft Outlook profiles on your computer is that you have to select the correct Microsoft Outlook profile every time that you start the Microsoft Outlook mail interface. This may cause failure in automation applications that import Microsoft Exchange public folders because the Choose Profile dialog box may appear when the import starts.

To verify if your Microsoft Outlook profile runs in Cached Exchange mode, follow these steps:

1. Click Start, point to Settings, and then click Control Panel.
2. In Control Panel, right-click Mail, and then click Open.
3. In the Mail Setup - Outlook dialog box, click E-mail Accounts.
4. In the E-mail Accounts dialog box, click View or change existing e-mail accounts under E-mail, and then click Next.
5. In the E-mail Accounts dialog box, click Microsoft Exchange Server, and then click Change.
6. In the Exchange Server Settings dialog box, verify if the Use Cached Exchange Mode check box is selected.
