Troubleshoot Cached Exchange Mode

This feature requires you to use a Microsoft Exchange account in Cached Exchange Mode. Most home and personal accounts do not use Exchange.

ShowI can't turn on Cached Exchange Mode.

One or more of the following may apply:

ShowYou do not have an Exchange e-mail account in your Microsoft Outlook profile.

This feature requires that your Outlook profile contain an Exchange server e-mail account.

ShowYour Exchange server administrator may have disabled this functionality.

Exchange server administrators have the ability to disable this feature in Outlook. For more information, contact your Exchange server administrator. Additional information for administrators is available in the Microsoft Office Resource Kit.

ShowYou have installed Microsoft Terminal Services.

Cached Exchange Mode uses an Offline Folder file (.ost) (Offline Folder file: The file on your hard disk that contains offline folders. The offline folder file has an .ost extension. You can create it automatically when you set up Outlook or when you first make a folder available offline.). These files cannot be used if you have installed Microsoft Terminal Services for Microsoft Windows 2000 Server or Windows Server 2003. Installation of Terminal Services Client or the Remote Desktop Connection client does not prevent access to this feature.

ShowMy e-mail message is staying in the Outbox.

When you are using Cached Exchange Mode, a message may remain in the Outbox for up to one minute until the next synchronization with the computer running Exchange server occurs. If you want to send the message immediately, do the following:

  • On the Tools menu, point to Send/Receive, and then click Send All.

ShowI am only receiving message headers.

Check the Cached Exchange Mode setting to see if Download Headers is selected. You can change the behavior of how items are retrieved by selecting the option you want.

ShowHow?

  • On the File menu, point to Cached Exchange Mode, and then click Download Full Items, Download Headers and then Full Items, or Download Headers.

 Note   Cached Exchange Mode is available on the File menu only when you are using a Microsoft Exchange Server 2003 e-mail account. For more information on the version of Exchange server you are connecting to, contact your Exchange server administrator.

ShowI want to download headers only, but the option is not available.

Download Headers followed by the Full Item and Download Headers are available only when you are using a Microsoft Exchange Server 2003 e-mail account. For more information on the version of Exchange server you are connecting to, contact your Exchange server administrator.

ShowMy e-mail messages "trickle" in.

When Microsoft Outlook synchronizes with Microsoft Exchange Server 2003, the default setting is to download headers first, then to begin downloading the full item, including attachments, so you can begin working immediately. If a connection to the Exchange server is available, you can open or select a header-only item, and then Outlook will immediately retrieve the full item. You can change the behavior of how items are retrieved by selecting the option you want.

ShowHow?

  • On the File menu, point to Cached Exchange Mode, and then click Download Full Items, Download Headers and then Full Items, or Download Headers.

 Note   Cached Exchange Mode is available on the File menu only when you are using a Microsoft Exchange Server 2003 e-mail account. For more information on the version of Exchange server you are connecting to, contact your Exchange server administrator.

ShowI want to use Remote Mail with Cached Exchange Mode.

Cached Exchange Mode uses a local copy of your Exchange server mailbox that is saved on your computer as an Offline Folder file (.ost) (Offline Folder file: The file on your hard disk that contains offline folders. The offline folder file has an .ost extension. You can create it automatically when you set up Outlook or when you first make a folder available offline.). Remote Mail can also use the .ost file, but in a different way. Remote Mail is designed to retrieve items from the Inbox only. Cached Exchange Mode provides far richer functionality than Remote Mail, including the ability to work with all folders in your mailbox. You cannot use both Remote Mail and Cached Exchange Mode.

ShowMy Offline Address Book is not updating when I use Cached Exchange Mode.

The Offline Address Book (OAB) is automatically updated every 24 hours, unless Microsoft Outlook is set to Download Headers or Outlook has detected a slow network connection and On Slow Connections Download Headers Only is selected. You can change these options.

ShowHow?

  • On the File menu, point to Cached Exchange Mode, and then click Download Full Items, Download Headers and then Full Items, or Download Headers.

 Note   Cached Exchange Mode is available on the File menu only when you are using a Microsoft Exchange Server 2003 e-mail account. For more information on the version of Exchange server you are connecting to, contact your Exchange server administrator.

You can update the Offline Address Book manually. On the Tools menu, point to Send/Receive, and then click Download Address Book.

ShowI am unable to change the folder where my Offline Folder file (.ost) is saved.

Cached Exchange Mode uses an Offline Folder file (.ost) (Offline Folder file: The file on your hard disk that contains offline folders. The offline folder file has an .ost extension. You can create it automatically when you set up Outlook or when you first make a folder available offline.). Because the .ost file is in use when Microsoft Outlook is running in Cached Exchange Mode, you cannot specify a new file location.

To change the location, do the following:

  1. On the Tools menu, click E-mail accounts, select View or change existing e-mail accounts, click Next, select the Exchange e-mail account, and then click Change.
  2. Clear the Use Cached Exchange Mode check box.
  3. Exit and restart Outlook.
  4. On the Tools menu, click E-mail accounts, select View or change existing e-mail accounts, click Next, select the Exchange e-mail account, click Change, and then click More Settings.
  5. Click the Advanced tab, click Offline Folder File Settings, and then click Disable Offline Use.
  6. On the Tools menu, click E-mail accounts, select View or change existing e-mail accounts, click Next, select the Exchange e-mail account, click Change, and then click More Settings.
  7. Click the Advanced tab, click Offline Folder File Settings, and then in the File: box enter the new file location.
  8. On the Tools menu, click E-mail accounts, select View or change existing e-mail accounts, click Next, select the Exchange e-mail account, and then click Change.
  9. Select the Use Cached Exchange Mode check box.
  10. Exit and restart Outlook.

ShowWhen I use ActiveSync with Cached Exchange Mode, performance seems to decrease.

For best performance, make sure your mailbox settings are downloading full items. Full items are required by the ActiveSync software.

  • On the File menu, point to Cached Exchange Mode, and then click Download Full Items.

 Note   Cached Exchange Mode is available on the File menu only when you are using a Microsoft Exchange Server 2003 e-mail account. For more information on the version of Exchange server you are connecting to, contact your Exchange server administrator.
