Retain Exchange

Level 1

There are two major sections to setting up Retain to connect to an on-premise Exchange server.

One is the Impersonation User and the other is the Exchange Forest.

Impersonation User

In the Exchange Module the Impersonation User is formally called the Global Catalog User.

This user needs to exist in Exchange and will have a mailbox even though it won't be used. This user also needs to ApplicationImpersonation rights. Those rights can be added to a User in the 2013 Exchange Admin Console.

Appendix G of the Admin Guide describes how to set it up in Exchange 2010 & 2007.

Hands On

Create your own Impersonation User account and use it as part of your Retain Exchange Module.

Open the Exchange Admin Console.

Create a new user for your Retain system and assign it ApplicationImpersonation rights.

Level 2

Hands On

Go to the Exchange server and check the status of the Impersonation User
