With thousands of emails exchanged every day even in a single medium-sized organization, user’s mailboxes might quickly get full. In Exchange Online, you can try to overcome this problem by enabling archive mailboxes and telling users to move old items to them. Unfortunately, the human factor can be the weak link in the process. This is where Microsoft 365 archive policies come into play, offering you a centralized and automated way to keep your users’ primary mailboxes below the cap.Continue reading "How to set up Microsoft 365 archive policy"

[Update] This post was updated on June 22, 2023 because of the plans to deprecate Client Access Rules in Exchange Online.
Client Access Rules (or CARs) in Exchange Online are rules that you can use to control which client connections are allowed and not allowed to access your Exchange Online organization. They let you define the conditions based on various properties of a client. These can be, for example, the protocol they use to connect, their IP address or an Active Directory attribute. Thanks to that, you have an option to block (or allow) certain client connections to better protect your Microsoft 365 (Office 365) organization.Continue reading "How to block access to your Exchange Online organization using Client Access Rules"

YubiKey is one of the most popular security keys on the market. A security key is a small device that lets you authenticate yourself when you sign in to a service (e.g. Google, Facebook, email clients, etc.) using a multifactor authentication (MFA, 2FA). It can support multiple authentication standards, also in the Microsoft 365 ecosystem, and is far safer than, for example, the SMS code verification.Continue reading "How to deploy YubiKey in Microsoft 365"
