Hey everyone! 👋

I’m currently exploring the possibility of completely replacing Microsoft 365 with open-source alternatives. The goal is to get similar functionality (email, files, office, video calls, device management, automation) without subscriptions and closed ecosystems.

📌 What I’m trying to replace: • Azure AD / Entra ID → FreeIPA + Samba AD + Keycloak • Exchange, Outlook → Zimbra Community Edition • OneDrive, SharePoint → Nextcloud + Collabora Online • Teams, Zoom → Jitsi Meet + Nextcloud Talk • Intune, TeamViewer → MeshCentral • Azure Monitor → Zabbix • Power Automate → n8n • Defender XDR → Wazuh • Microsoft Entra MFA → Authelia

🔹 Benefits of This Approach

✅ Full control over data (self-hosted) ✅ No subscriptions or user limitations ✅ Highly customizable ✅ Zero Trust Security (SSO, 2FA, XDR)

🔻 Challenges

❌ Requires setup on VPS or local servers ❌ Maintenance and updates rely on the IT team ❌ Some features may differ from Microsoft 365

💬 Questions for the Community:

1. Is this realistically feasible for an organization with 50-100 users?
2. What has been your experience with similar solutions?
3. What potential pitfalls should I be aware of?
4. Are there better open-source alternatives I should consider?

I’d love to hear your thoughts and advice!
