Exchange 2003 Migration Tip: Creating Administrative Credentials

As the scrambling continues to migrate to new messaging systems with the discontinuation of support for Microsoft Exchange 2003, we thought we would give insight into some of the issues that can be encountered migrating off this platform from our years of experience helping customers through the process. In this blog post we will provide the steps you need to create a new administrative account specific to your migration. You will need to create a new account because the security default of the Exchange Server explicitly denies any user that is a member of any existing domain administration, schema administration, or enterprise administrator groups administrative rights to mailboxes regardless of the permissions you grant. You can get around this security precaution by following our step-by-step instructions on creating an administrator account for your migration project.

To create an account, perform the following from your Exchange Server 2003 machine:

  1. Open the Active Directory Users and Computers snap-in
  2. Navigate to the organizational unit (OU) in which you would like to create the administrative account
  3. Right click on the OU and select New > User
  4. Enter “MigrationWiz” as the first name
  5. Enter “MigrationWiz” as the user logon name and optionally select a user principal name (UPN) domain
  6. Click Next
  7. Enter a password and confirm the password
  8. Uncheck User must change password at next logon
  9. Click Next
  10. Click Next to assign a mailbox
  11. Click Finish
  12. Right click on the MigrationWiz user in the Active Directory Users and Computers snap-in and selectProperties
  13. Click on the Exchange Advanced tab
  14. Click Hide from Exchange address lists
  15. Click OK

To grant the account access, perform the following from your Exchange Server 2003 machine.
1. Open the Exchange System Manager snap-in
2. Expand Servers node

Exchange 2003 system manager
3. Right click on the server you wish to grant administrative mailbox access to and select Properties
