The Microsoft 365 functions I run every day — in one module.

MyPSFunctions is a working PowerShell toolkit for administering Entra ID, Exchange Online, SharePoint, Teams, Azure and Microsoft Graph. 300+ functions, grouped by service, refined in production tenants and published as-is.

What it is

A practitioner's toolkit, not a polished product.

Every function here earned its place by solving a real problem in a live Microsoft 365 tenant — a migration to run, a report to pull, an incident to chase down. They follow PowerShell's Verb-Noun grammar and carry a service prefix, so finding what you need is just Get-Command.

Generate-MgConditionalAccessPoliciesReport
VERB

The action. Functions group by intent — Get, Generate, Connect, Convert, Restore.

PREFIX

The service it touches. Mg = Graph, EXO = Exchange Online, AAD = Entra ID.

NOUN

The target. What the function reads, builds or changes in the tenant.

Nine service domains

Organized the way you actually work.

Loaded as nested modules. A representative function or two from each — the full set is one Get-Command away.

Behind the module

I build the automation, then publish it.

I'm John — I've spent 20+ years architecting, securing and automating Microsoft 365 environments for organizations across Canada, the United States and Europe.

MyPSFunctions is where the tooling I write along the way lives. It isn't a commercial product and it comes with no support — it's the honest, working toolkit of someone who administers these tenants for a living, shared in case it saves you the same hour it saved me.

If it's useful to you, or you just want to talk PowerShell and M365, I'd be glad to connect.
