Microsoft keeps the service running, but protecting the data is your job. We copy mailboxes, files and chats every day to a separate archive in Europe and test restores before you need them.
UreTech sets up and manages Microsoft 365 backup for SMEs and professional firms: Exchange Online mail, OneDrive, SharePoint and Teams are copied every day to an archive outside Microsoft, in European Union data centres. Microsoft keeps deleted items only for a limited time, so a separate backup is the only way to recover data lost months ago, encrypted by ransomware or deleted along with a former employee’s account.
We use widely adopted tools such as Veeam Backup for Microsoft 365, Synology Active Backup for Microsoft 365 or Acronis, chosen on the number of users and where you want the copies kept. The service covers setup, daily job checks, a documented restore test and support with a reply within one working day.
The situations we hear about most often.
A deleted email emptied from the bin stays recoverable for 14 days, 30 at most if the admin extended it. Then it is gone.
Remove the licence of someone who left and after 30 days the mailbox and OneDrive disappear, along with contracts and client correspondence.
If a PC is encrypted, OneDrive uploads the encrypted files to the cloud too. Sync is handy and spreads the damage as well.
A dispute asks for correspondence from two years ago. Without a copy kept separately, finding it is often impossible.
One contact, from setup to restore test.
Personal and shared mailboxes and archives, with calendars and contacts. Restore a single email or the whole mailbox.
Files, versions and permissions of SharePoint sites and personal OneDrives.
Chats, channels and files shared in teams, saved along with the team structure.
Archive in an EU data centre or on a NAS at your office, with a second off-site copy.
An immutable copy that no account, not even the admin, can delete before it expires.
Daily job checks, an alert if anything fails and a documented restore test every quarter.
Microsoft 365 has useful retention features, built for yesterday’s mistakes. The model is shared responsibility: Microsoft makes sure the service runs, protecting the content is up to whoever uses it. Since 2024 Microsoft also sells a separate backup service, Microsoft 365 Backup, priced apart from the licences.
| Situation | Microsoft 365 alone | With a separate backup |
|---|---|---|
| Email deleted and bin emptied | Recoverable for 14 days, extendable to 30 | Recoverable for the whole retention you choose, even years |
| File deleted from SharePoint or OneDrive | Recycle bin for 93 days | Any saved version, older ones too |
| Former employee’s account removed | Mailbox and OneDrive kept 30 days by default | Data kept even after the licence is removed |
| OneDrive encrypted by ransomware | Restore OneDrive to a day in the last 30, user by user | Restore from a copy ransomware cannot reach |
| Admin account compromised | The intruder can delete data and settings | Immutable copy on a system with different credentials |

Microsoft Purview retention policies help with legal obligations, but they will not put a site or a mailbox back the way it was last Tuesday. That takes a backup with restore points.
Technology ecosystem
Our partnerships cover websites and e-commerce. Around them sits the rest of the business: ERP, servers, backups and artificial intelligence. For each technology we say exactly what we do: we integrate, design, set up and build.
Clusters, virtualisation and backups sized on the real workload, with monitoring and updates. We also migrate from VMware to Proxmox, with a cut-over plan and agreed downtime.
Cloud infrastructureManaged servers and VPSBackup and disaster recovery
We help you choose servers and storage that fit the workload and the budget, supply them and set them up on site, with virtualisation and backups already in place.
TWO-MINUTE CHECK
Eight real Microsoft 365 situations. For each one, tell us whether you would recover everything today. The ring shows how well you are covered and below you see what to fix first.
Answer the first situation to light up the ring.
Every situation is covered: keep testing restores every quarter.
Microsoft 365 retention periods as documented on Microsoft Learn, checked on 9/11/2026: they can change with your tenant’s licences and settings.
A short report with job results, space used, users added or removed and the quarter’s restore test: what we restored, how long it took and the outcome. When an employee leaves, their data stays in the backup for the agreed period and the licence can be freed straight away.
The archive credentials are separate from Microsoft 365: even if someone gets into the tenant with the admin account, they cannot delete the copies.
Five steps, without stopping your mail.
Users, shared mailboxes, SharePoint sites, teams and how much data there is.
How long to keep copies, where, and who can restore. All in writing.
An app registered in Microsoft Entra with only the permissions needed, nightly jobs and an immutable copy.
We restore a test mailbox and site and show you the result.
Job reports, alerts and a restore test every quarter.
Activation takes a few days: the first full backup depends on the amount of data and can take a night or a few days, while mail and files stay usable. The cost is a monthly fee per user that covers the tool licence, space in an EU data centre and job monitoring. You find it in the quote, with separate items, after the free tenant review.
If you already have a Synology NAS at the office, Active Backup for Microsoft 365 comes with the NAS and the main copy can stay there. In that case we only charge for setup and a second off-site copy.
For companies and firms with 5 to 300 users who work on Microsoft 365 and cannot afford to lose correspondence, contracts or projects. It is especially useful if your clients fall under NIS2 and ask you to prove you have protected copies and restore tests: the quarterly report works for their questionnaires too. If the backup also covers office servers and PCs, we add it to the backup and disaster recovery plan, so you get a single report.
For email signatures we have our own software: ure·signatures puts the same company signature on Outlook desktop, web and mobile, shared mailboxes included, priced per company with a Free plan. How we set it up and what it costs is on our Microsoft 365 email signatures page.
Tell us how many users you have and whether you use SharePoint and Teams. We reply within one working day with the first questions and a date for the tenant review.
We will email you within one working day to book the 30 minutes. If it is urgent, message us on WhatsApp.
