Outlook 2010 Removing Cached Entries from Outlook

A cached entry is an email address that has been saved by Outlook when you last sent to it. This appears when you begin to type the email address into the "To" field when composing an email.

Why might I need to remove it?

When using outlook it is possible for cached entries to become corrupt. This is usually caused by a change being made to the destination mailbox, for example the mailbox being moved or deleted and recreated. This will mean that when sending to such a mailbox using a cached entry, it will attempt to deliver the email to the old destination. This will result in a bounce back being generated.


Removing Cached Entries:

  1. To remove cached entries via outlook the first step is to open up outlook and open a new email.
