Modern Workplace Mastery – Day 4: Baseline Tenant Security and Defaults

Modern Workplace Mastery: Day 4 - We stop treating Security Defaults as a forever solution and move to a small, designed Conditional Access baseline. MFA is expected, not a favour

Modern Workplace Mastery – Day 3: Licensing Strategy & First Purchases

Microsoft licensing isn’t just “how do I get Word and Teams?”. It’s a set of capability bundles that quietly decide how secure you can be, how easily you can manage devices, and how painful your support queue becomes six months from now.

Modern Workplace Mastery – Day 2: Domains, UPNs and Email Addresses

This Modern Workplace Mastery post follows CalderCloud Co as we move from “we’ve created a tenant” to “we’ve created an identity that people can trust”. You’ll leave with a practical naming standard for domains, sign-in names (UPNs), email addresses, shared mailboxes, rooms, and collaboration spaces - designed to scale for the next ten years without turning into a support nightmare.

Modern Workplace Mastery – Day 1: Creating the CalderCloud Microsoft 365 Tenant

Modern Workplace Mastery: CalderCloud Co has a clear Tenant Foundations Charter and a shared understanding of why its Microsoft 365 tenant exists. What it doesn’t have yet is a tenant. In this post, we follow the single person who will actually click “Sign up”.

Modern Workplace Mastery: Day 0 – The CalderCloud Foundations Workshop

Why we slow down on Day 0 so we don’t spend years fixing avoidable mistakes. Instead of rushing into a free trial, we at CalderCloud lock the mouse, get the right people in a room and run a Day 0 workshop to ask the “stupid” questions nobody ever writes down.
