Speed up Outlook IMAP connections

This scenario is applicable only if you are running Outlook 2007. If an additional mailbox is added to a user's Office 365 mailbox (for example, a shared or resource mailbox), Outlook may slow down when it tries to connect to the additional mailbox. By default, Outlook 2007 caches only non-mail folders. Mail folders use an online connection to the Exchange Online servers. To help improve performance, cache the mail folders of the additional mailboxes.

To do this, follow these steps:

  1. Start Registry Editor. To do this, click Start, click Run, type regedit, and then click OK.
  2. Expand the following registry subkey: HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook
  3. Right-click Outlook, point to New, and then click Key.
  4. Type Cached Mode, and then press Enter to name the new key.
  5. Right-click Cached Mode, point to New, and then click DWORD Value.
  6. Type CacheOthersMail, and then press Enter to name the new value.
  7. Right-click CacheOthersMail, and then click Modify.
  8. In the Value data box, type 00000001, and then click OK. Exit Registry Editor, and then start Outlook.
