What was working fine

I had my tenant in Microsoft 365 for nearly 10 years. Both of my domains lived there, mahon.pro for professional usage, and petemahon.net for anything personal.

It was invaluable for keeping up with the ever-evolving beast which is M365. Or is it Office? I can’t bring myself to call it all CoPilot. Starting with office.com, then microsoft365.com and then more recently microsoft.cloud. Access to a full Exchange server, 1TB of SharePoint storage, Teams, and of course the 1TB OneDrive and 50GB mail storage. All for a measly $12.99 a month. I also managed the DNS for my domains in M365, noting that the ease of having Microsoft manage these meant for a much less manual setup when adding domains. The security of the platform alone kept me hooked and I therefore evangelised it for SMBs (as a managed service).
