Practical answers about Microsoft 365, Intune, Exchange and security for small businesses, plus the other topics 3DBooster works with every day.

Microsoft 365

What does a Microsoft 365 administrator do for a small business?

Setting up users, licences, mailboxes, Teams and SharePoint, managing permissions and fixing problems. That keeps Microsoft 365 secure and organised, even without an in-house IT department.

Practical knowledge item
Intune

How do you manage business laptops with Intune?

The basics of enrolment, policy, apps and secure access in one managed workplace.

Practical knowledge item
Intune

What is Microsoft Intune, and does my business need it?

Intune manages laptops and phones centrally: apps, updates and security settings. Most useful once you have several devices and want to be sure they are secure and up to date.

Practical knowledge item
Intune

Can employees use their private phone for work?

Yes, securely: with app protection in Intune only the business data is protected, without taking over the whole private device.

Practical knowledge item
Intune

What is Autopilot, and how do I get a new laptop ready quickly?

With Autopilot a new Windows laptop configures itself: the employee signs in and apps and settings arrive automatically.

Practical knowledge item
Exchange Online

Why do my emails end up in spam? SPF, DKIM and DMARC explained

These are three DNS settings that prove an email really comes from your domain. If they are missing or wrong, emails are more likely to be marked as spam or rejected.

Practical knowledge item
Exchange Online

When do you choose a shared mailbox?

For addresses like info@ or administration@ that several people use. A shared mailbox usually does not need its own licence, and you decide per person who gets access.

Practical knowledge item
Security

What is multi-factor authentication (MFA), and why does it matter?

Besides your password, MFA asks for a second confirmation, for example in an app. A stolen password alone is then not enough to sign in to Microsoft 365.

Practical knowledge item
Security

How do you know whether your Microsoft 365 is well protected?

Look at things like MFA, access rights, email settings and the security of devices. Microsoft Secure Score gives a first indication; a security check shows what can concretely be improved.

What do you need to arrange when an employee leaves?
