After accepting an invitation in Outlook, I have lost the original email. How do I get it back? I have looked in my sent and in my deleted folders.
Go to your Calendar and click on the Appointment. The contents of the original invitation will be under Start/End time fields (depending on your layout and monitor size, they might be squeezed and difficult to spot at first).
For future you can disable automatic deletion by following:
- Go to File tab.
- Click Options then Mail.
- Under Send messages section you will see a checkbox "Delete meeting requests and notifications from Inbox after responding". Uncheck it.
