# Office 365 OAuth2

> Administrators can configure Personal Rooms so users sign in with their institution's Office 365 accounts, with no app to install.

Office 365 OAuth2 lets your users sign in to Personal Rooms with the Office 365 accounts they already have. There is no app to install — Blindside Networks configures the connection for you.

Users can sign in when their Office 365 email address belongs to the host domain assigned to your account.

## What we need from you

Your institution's **Host Domain** — the domain of the email addresses hosted by Office 365. For example, `blindsidenetworks.com`.

Send it to [support@blindsidenetworks.com](mailto:support@blindsidenetworks.com), along with the name and email address of the person to set up as your Personal Rooms administrator.
