Delayed delivery of messages in Outlook 2016 for Windows


The default is for Outlook to have the Use Cached Exchange Mode field checked. When Cached Exchange Mode is on, a copy of your mailbox is stored locally on your computer. This provides quick access to your data, but in this state, mail cannot be queued to be sent when the Outlook mailbox is not open.

  1. In Outlook, click the File tab.
  2. Click Account Settings twice.
  3. On the email tab, click your @Dartmouth.EDU account to select it.
  4. Click Change.
  5. Un-check Use Cached Exchange Mode.
  6. Click Next.
  7. If told, you must restart Outlook, click OK.
  8. Click Next.
  9. Click Finish.
  10. Click Close.
  11. Exit and restart Outlook.
