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"

Distribution lists are known under a few different names. Distribution groups, contact groups and distribution lists – all refer to the same feature. The primary purpose of a distribution list is to send emails to multiple recipients – yes, as simple as that. The simplicity of their design and the idea behind distribution groups make them an essential email feature. It’s no wonder they have been around since the earliest versions of Exchange Server and that they can be found in Office 365 (Microsoft 365), as well. Although they have survived in a very similar form, Office 365 also offers a redesigned variant of distribution lists – Office 365 Groups.
By the way, Office 365 Groups and Microsoft 365 Groups are the same thing. Officially, they’re called Microsoft 365 Groups after a rebranding, but most people use the old name. You can voice your doubts in the comments if you like.
Office 365 focuses on using the upgraded version of distribution groups – Office 365 Groups. I will start with a quick comparison between the two features. Later on, I will describe a few common administration tasks concerning Office 365 distribution lists.Continue reading "Distribution lists in Office 365 – administration tips"
