## 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, and
the reason is rarely a feature. It is the operations work that disappears.

## What to watch

Two things get missed regularly.

Storage moves from a file server with permissions that grew over fifteen years into
SharePoint, and the permissions move with it. A migration is the only good moment to clean
that up.

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