Scripts and tools

My Slide Decks

This page will contain my own scripts and slide decks from my presentations. All of which are hosted and made available through my GitHub.

On this page, you will also find other useful scripts and tools from the community, which I find useful and can recommend.

My tools

I build tools and scripts for IT professionals and make them all available for free. Here’s what’s currently available:


PowerShell scripts & toolkits

A collection of community scripts released on GitHub in 2025 and 2026, built around Microsoft 365, Exchange, and Entra ID administration:

  • Entra SOA Manager Toolkit — converts AD-sourced users to Entra ID as the Source of Authority, handling the full transition cleanly
  • Exchange Mailbox & Group SOA Manager — manages Source of Authority for Exchange mailboxes and groups during hybrid migrations
  • Exchange Mailbox SOA Bulk Updater — bulk version of the above for large-scale environments
  • M365 Migration Scripts Toolkit — a collection of scripts for common Microsoft 365 migration scenarios
  • EXO-ReEnable-AutoReply — re-enables auto-reply settings in Exchange Online after migrations where they get wiped
  • ADUsers-Signature-Data — extracts and manages email signature data from Active Directory user attributes
  • Certificate Exporter — exports certificates to multiple formats including PFX and PEM for use across different systems

Web tools

Free browser-based tools anyone can use, no account required:

  • MailPosture — audits a domain’s email security posture in seconds. Checks SPF, DKIM, DMARC, MTA-STS, DANE, BIMI, DNSSEC and more, showing exactly what’s configured, what’s weak, and what’s missing
  • DomainRadar — checks DNS health, email configuration, and Microsoft 365 DNS settings for any domain
  • BurnLink — send a password or sensitive text as a one-time link that permanently self-destructs after it’s opened
