5. What is automapping?

Automapping is a labour-saving device that was introduced with Exchange 2010. Previously, if you had Full Access to another mailbox (another person’s or a generic/project account), you – the user – had to map in that mailbox to your copy of Outlook for you to be able to access it. This involved several clicks and was considered to be ‘rather technical’. Now, if you are given Full Access to another mailbox, Exchange sets that mailbox to ‘automap’ in Outlook and it appears automatically without having to click on or type anything.

Possible related problems include:
  1. If you had already manually mapped that mailbox in, you may get two entries, both of which cache (N.B. this only occurs when an individual is given Full Access anew. If Full Access was granted in the more distant past this problem should not be apparent.)
  2. The two entries (from the situation above) can confuse each other as to where to file Sent Items (see http://support.microsoft.com/kb/981245).
  3. If you are particularly unlucky the second mailbox may push you over the ‘500 folders per Exchange mailbox server limit’.
