Risk impact

Microsoft 365 requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install Microsoft 365 if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Microsoft 365 has earned a good reputation and can be trusted.

Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing an Edge add-on, especially ones with higher risk impact and/or higher risk likelihood.

User reviews
The extension is useful and worked very easily. but there are some lacking capabilities that make it less polished to give 5 stars. - No way to provide feedback directly in app - No option to add more "recent" docs in list. Ideally I would prefer an expanded list before i open OneDrive, or give me settings to show 3/5/10 items in list similar to MyApps Extension. - No settings area to customise extension (This customisation should be stored within Azure AD for work accounts) - Loading Teams automatically loaded a guest account to another tenant, rather that the home tenant. Had no choice but to sign in and switch. Would prefer it have a choice on load, or force direct to home tenant. -"View my account" is not very obvious and the structure of the view is not standard to Microsoft. I would recommend aligning to Microsoft standard design patterns and Fluent.
