Dear customers,
We want to inform you early on that support for Microsoft Exchange Server 2019 will be permanently discontinued on October 14, 2025. From that date, Microsoft will no longer provide security updates, bug fixes, or technical support. This has significant implications for the operational security and stability of your email infrastructure — regardless of whether you rely on Windows or Linux-based systems.
What Does This Mean for You Specifically?
-
No technical support: In the event of problems or outages, you will no longer receive assistance from Microsoft.
-
No bug fixes: Functional issues or stability problems will remain permanently unresolved.
-
No security updates: Newly discovered security vulnerabilities will no longer be patched — your systems are potentially exposed to attacks.
Act Now: Switch to Exchange Online
Continuing to operate Exchange Server 2019 beyond the end of support is not recommended — particularly for security and economic reasons. Switching to Exchange Online is the logical and sustainable step to ensure you continue to rely on a secure, maintenance-free, and modern email system going forward. Exchange Online Plan 1 with 50 GB mailbox size per user is already included in many Microsoft 365 plans — for example, in Microsoft 365 Business Premium. This gives you not only a powerful email system but also the benefits of a comprehensive security and collaboration platform.
Your Advantages with Microsoft 365 Business Premium:
- Secure and reliable: Always up-to-date security standards thanks to regular updates — without any action on your part.
- Comprehensive protection: Features like threat protection, multi-factor authentication, and data loss prevention are already built in.
- Flexible working: Full access to emails and data — in the office, at home, or on the go.
- Future-proof: Scalable, cloud-based, and expandable at any time — without additional server monitoring and maintenance.
