  Draft, not yet reviewed. Our work usually starts with Exchange Online and continues with Entra ID. The mailbox migration is manageable. Conditional access, guest accounts and the question of who is actually a Global Administrator take considerably longer.

## What it is

Microsoft 365 bundles Exchange Online, Teams, SharePoint and OneDrive, along with device
and identity management. The common denominator is Entra ID: nearly every permission in
the suite hangs off it.

## What it is for

Working across sites without running the servers for it. That has become the default,
usually because the work of running your own servers goes away.

## What to watch

Two things get missed regularly.

Storage moves from a file server with permissions that grew over time into SharePoint, and
the permissions move with it. They are best cleaned up during the migration.

And the default retention in the recycle bin is not a backup. If you need to restore from
weeks ago, plan that separately.
