The settings below are typical values required for the correct configuration of Office 365.

NOTE: On rare occasions, Microsoft have been known to stray slightly on the values of some of these entries. However, until the domain is verified, it is only possible to know the verification code for certain. The other values are guesswork based on previous experience.

If we have asked you to configure your own domain as part of our setup process, then we may require you to NOT make changes to the entries detailed within the "Stage 2" until we specifically request it to be done. This is to prevent emails from starting to arrive in the new system before users have the ability to receive them. Please speak to us if you are unsure.
