Who this tends to suit
These are the conversations that come up most, and none of them require a formal arrangement to start.
Web and marketing agencies
You build the site, then inherit the email problems attached to the domain. DNS, SPF, DKIM and DMARC, mail landing in junk, a form that sends to a mailbox that was never really a mailbox.
Computer repair and break-fix shops
You are excellent with the machine in front of you. The tenant behind it, with its licences, Conditional Access policies and device enrolment, is a different job and not always one worth staffing for.
VoIP and communications providers
Teams integration, call routing to shared mailboxes, identity that has to line up before any of it works.
Cyber insurance brokers
The questionnaire asks about MFA, admin accounts and backups. Your customer needs somebody to make the answers true rather than optimistic. We do the technical work. We do not advise on insurance and we cannot promise a policy outcome.
Compliance consultants
You know the framework and what it requires. We implement the Microsoft 365 controls underneath it and document what changed, so your evidence is a configuration rather than an intention.
Providers who do everything except this
General IT support who would rather not take on a tenant cleanup, or a firm whose Microsoft 365 person just left.
