Microsoft 365 management & support for companies
Set up. Secure. Maintain.
Microsoft 365 is not merely a software installation but a company platform. Getting started is usually quick — the real work begins afterwards: users join and leave, teams grow, permissions change, licences run on.
✓ Migration & setup
✓ Users & permissions
✓ MFA & security
Services
What we take on in Microsoft 365.
Not every company needs all of it. What matters is that the services in use are set up and maintained deliberately rather than accumulating over time.
Setup & migration
Moving mailboxes, calendars, contacts, public folders and local file shares — including the question of which data stays on premises.
Exchange Online
Email, calendars, distribution lists and shared mailboxes: setup, maintenance and support during daily operation.
Teams & SharePoint
Structure instead of sprawl: which teams are needed, where files live, how channels are named and how external partners are included.
Users & permissions
Creating and removing accounts, assigning access rights, reviewing shares and handing over OneDrive data cleanly when someone leaves.
MFA & administration
Multi-factor authentication, administrative access, break-glass accounts and the question of who is responsible in an emergency.
Licences
Which licences are booked, which are actually used, and does the model still match the current number of workplaces?
Common issues
What usually ails grown environments.
Microsoft 365 is rarely introduced in one go. First comes Exchange Online, then Teams, then OneDrive, later SharePoint and MFA. When these steps are not coordinated, the same patterns keep appearing.
✓ Too many teams, duplicate channels and no naming rules
✓ External shares that nobody oversees any more
✓ MFA only partly enabled, especially on admin accounts
✓ Licences for accounts that have long stopped being used
✓ No backup concept for data that exists only in the cloud
Migration
The move is only the first step.
A migration is technically feasible. Whether it succeeded only shows in whether the new environment fits daily work: where files are stored, which teams are really needed and how staff are introduced to it.
1
Inventory
Which mailboxes, file shares, user accounts, devices and mobile access exist, and what of it is still in use?
2
Target picture
Where should files live in future, which permissions apply and which data deliberately stays on premises?
3
Migration
The technical move of mailboxes, calendars, contacts and files — planned around the fact that work continues meanwhile.
4
Aftercare
Introduction, adjusting permissions and handover into ongoing support. Only then is a migration complete.
Keeping Microsoft 365 under control.
Whether migration, cleaning up a grown environment or ongoing support: the first step is always looking at what is actually configured today.
Frequently asked questions
Does Microsoft 365 need its own backup?
Microsoft operates the platform, but responsibility for being able to restore your own data remains with the company. That is why we check which data is stored only in the cloud and how it is backed up. More on this on our Backup & Recovery page.
How long does a migration take?
That depends on the data volume, the number of mailboxes and the existing storage structure. It can only be said reliably after the assessment — any time frames given beforehand would be guesswork.
What happens to the data of former employees?
Mailbox and OneDrive data are handed over or backed up before deactivation. If this is not arranged, data is lost or licences remain active that nobody uses any more.
Is MFA mandatory?
Microsoft has made multi-factor authentication mandatory for access to the Microsoft 365 admin center. Regardless of that, MFA makes sense for all accounts with elevated privileges.
