Office 365 default sign on rules
The Office 365 app in Okta has two default sign on rules. This set of rules is unique to the Office 365 app. It ensures that only more secure clients get access to the Office 365 apps. This set contains the following two rules:

- Specify how frequently the user will be prompted to re-authenticate.
- Require the user to successfully complete the MFA prompt and specify how frequently the user will be prompted for MFA. See © 2021 Okta, Inc. All Rights Reserved. Various trademarks held by their respective owners. .
