While you’re unlikely to actually use the domain name once you have fully configured your organization’s tenancy, it’s important to note that the tenant name cannot be changed after you configure your Microsoft 365 subscription. If a tenant already exists with that name, you’ll be alerted and required to select an alternative. When you initially create the tenancy, a check is performed against your proposed tenancy name. This name has to be unique, and no two organizations can share the same tenant name. The tenant name is in the format, where name is the name you want to assign to your organization’s tenancy. When you create a Microsoft 365 subscription, the subscription tenancy is automatically assigned a custom domain.

You’ll also need to know how to configure that domain name to work with a variety of Microsoft 365 services, as well as configure user names and email addresses to leverage the new domain name. To master this skill you’ll need to understand how to configure a Microsoft 365 tenancy to use a DNS name managed by your organization. This section deals with managing domain name configurations for a Microsoft 365 tenancy. Manage Microsoft 365 subscription and tenant health Setup Microsoft 365 tenancy and subscription In this chapter you will learn about managing the Microsoft 365 domain namespace, how to plan a Microsoft 365 implementation, how to setup a Microsoft 365 tenancy and subscription, how to manage that subscription and tenancy’s health, and the steps that you’ll need to take to plan the migration and users from a traditional on-premises environment to a Microsoft 365 environment. Is an "all" mechanism anywhere in the record.Ĭonsidering all this, I would suggest to go with the syntax as provided by Although it is not against the rules, it is highly unusual to combine mechanisms with the redirect modifier.It contains valuable information regarding the skills you need to pass the exam.Īlthough it’s possible to simply start deploying Microsoft 365 once your organization has made the decision to adopt the technology, your organization will get more out of its Microsoft 365 deployment if some planning and design work has occurred before any Microsoft 365 services are configured. Any "redirect" modifier MUST be ignored if there "include" directive will generally be more appropriate.Īnd, a redirect modifier MUST not be combined with an all mechanism:įor clarity, any "redirect" modifier SHOULD appear as the very last The stays the same, there is no guarantee that the record atĭomain "B" will correctly work for mailboxes in domain "A",Įspecially if domain "B" uses mechanisms involving local-parts. Note: In general, the domain "A" cannot reliably use a redirect toĪnother domain "B" not under the same administrative control. In this example, mail from any of the three domains is described by This facility is intended for use by organizations that wish to apply “v=spf1 mx include: redirect:_”įrom the RFC, section 6.1 on the redirect modifier it reads: So in summary you would want to use something like. However each redirect counts towards the lookup count limits.
It's worth noting that any redirected domain's own SPF may contain further redirects, and they would cascade as expected. (Caveat: if a +all is encountered within a traversed include it will return matched, and trigger whichever result has been prepended to that include, usually a default +.
Of course, any all mechanism in the redirected domain's SPF would still apply if reached, unlike the -all in an include which would be ignored by returning not-matched to the include mechanism call. Therefore you cannot use redirect in combination with all, because the all mechanism will always be tested and satisfied first, and the redirect will never be processed. If any alternative mechanism term is satisfied in the record then the processing will stop at that term and return the evaluated condition, this includes any all mechanism that may be present. ie its position in the SPF record will not determne its order of processing. Unlike an include, once a redirect has been navigated it will not return to evaluate further terms, and although your positioning isn't invalid for clarity it should appear as the last term in the record since it will only be evaluated after all the other terms have been tested and passed over. The redirect is a modifier rather than a mechanism, and will only be considered after all other mechanisms have been tested.
