Changing Exchange Capitalization on Email Domain

I recently had a customer running SBS 2008 with Exchange 2007 ask me if they could have the domain name part of a user’s email address displayed with proper capitalization. As an example, instead of Joe@whitehouse.gov they wanted the email address to go out as Joe@WhiteHouse.gov.

This should be easy to do, I thought. So, I went into EMC and changed the spelling of the email to use capitalization, but it would never take hold. It turns out that simply changing the capitalization of the email address is NOT enough for EMC to recognize that a change has been made.

So here are the three steps required:

  1. Edit the email address for capitalization, but also make a change to the user (left side) part of the email address, then save
  2. Then re-edit the email address, fixing the left side of the email address
  3. Update the Offline Address Book (OAB)

So, let’s give it a try:

Step 1:

  • Go into EMC –> Recipient configuration –> Mailbox –> double click on the specific user –> click on the Email Addresses tab
  • Select the email address to be changed and click Edit
  • Change Joe@whitehouse.gov to JoeXX@WhiteHouse.gov and save

Step 2:

  • Select to edit the email address again
  • Change JoeXX@WhiteHouse.gov to Joe@WhiteHouse.gov and save

Step 3

  • From EMC, click Organization Configuration –> Mailbox –> Offline Address Book tab
  • Right click on ‘Default Offline Address Book’ and click Update

  • Note: you call also do the OAB update using the following PowerShell command:
    update-offlin eaddressbook –identity “default offline address book

These steps should be applicable to both Exchange 2007 and Exchange 2010.
