Deployment of the Exchange trial

Once you have finalized planning, it's time for you to deploy the trial. Some important key points that you will need to be aware of include:

  1. Verify the domain. Verification takes up to 48 hours. Do not expect to be able to use the new domain immediately after verification of the domain.
  2. Sign In Application doesn't work on Linux. If you are planning to use BPOS on a Linux box, don't expect it to be flawless. Microsoft only released the BPOS Sign In Application for Windows and Mac.
  3. Make minimal changes to your network configuration. You do not want to do too many customizations to the current configurations just to make a service/system work. Why? Undoing them will make more work for you if the trial doesn't pan out.
  4. Migration Tool doesn't work on SBS. If you plan for your local Exchange server to co-exist with the trial and your environment is on SBS, you will need an extra member server to install the Migration Tool onto.

Back-Out Plan

As with any service, every trial service that you deploy for users should have a back out plan. For Microsoft Exchange Online, setting and using a trial is fairly simple, but here are some guidelines for cleaning up a Microsoft Exchange Online deployment:

When a local Exchange server didn't coexist with Exchange Online ...

  1. Archive the emails from Microsoft Exchange Online to your local PST
  2. Reconfigure the user Outlook's profile to point back to the local server
  3. Import the PST that you've created in step 1

When a local Exchange server coexisted with Exchange Online ...

  1. Archive the emails from Microsoft Exchange Online to your local PST
  2. Remove forwarding -- Use Microsoft Online Migration Tool to do it
  3. Reconfigure the user's Outlook profile to point back to the local server
  4. Import the PST that you created in step 1

Proper planning for trial services is just as important as planning for the implementation. The success rate of production deployment approval will be much higher if you plan well.
