IceWarp vs MS Exchange in 2025
Still using MS Exchange Servers 2016 and 2019? Then support has already ended, leaving you without updates, tech help, or a security infrastructure. Luckily, IceWarp picks up where MS Exchange left off. Let’s see how they compare.
End of Support for MS Exchange Users
On October 14, 2025, Microsoft chose to end its ongoing support of MS Exchange Servers 2016 and 2019. Such a move has forced many users into the more expensive version of SE or M365. Click here to see how IceWarp stacks up against Microsoft 365.
This support cutoff has also introduced a myriad of problems for previous users. Say ‘goodbye’ to regular updates, bug fixes, and technical support, and ‘hello’ to data security risks and regulatory compliance issues.
So, what options do MS Exchange Servers 2016 and 2019 users have?
IceWarp Picks Up the Slack
It may be the end of the road for thousands of MS Exchange users, but luckily, IceWarp is here to pick up the baton and start running.
And to make the transition smooth, IceWarp acts as a drop-in replacement for MS Exchange. This flexible, all-in-one business email and collaboration toolbox even comes with both on-premise and Cloud solutions, or a hybrid of both to best fit your needs.
It’s this convenient migration flexibility that allows former MS Exchange users to seamlessly transfer all their Exchange data without ever switching off their Exchange accounts. Keep your workflows intact and get everything you need for email and collaboration, all in one solution.
Feature Comparison
Alright, we know IceWarp can provide a smooth transition from MS Exchange, but can it offer the same or even more useful features? See for yourself:
IceWarp users benefit from using tools they’re familiar with (no employee training or onboarding needed), while also increasing their creativity and efficiency with other features MS Exchange never offered them in the first place.
MS Exchange Security Concerns
One of the biggest issues with Microsoft cutting its support for MS Exchange is how widely this leaves the door open to security vulnerabilities.
MS Exchange users will no longer receive security updates. This leaves users’ servers vulnerable to attacks, with no help from Microsoft, which has also discontinued all technical support.
IceWarp’s world-class security can resolve this issue immediately. These are the following data security features that will protect your information where MS Exchange can’t:
- Antispam and antivirus protection;
- Option to choose the data center where you want your data to be stored, and it’ll remain there forever;
- Cloud and on-prem options, including hybrid setups;
- EU-based data privacy (GDPR compliance);
- 30-day user data backups, available upon request.
But if you’re still unsure, just take a few moments to review Microsoft’s track record of data leaks and security breaches. Now, imagine using MS Exchange with zero security updates… It’s simply a recipe for disaster.
Luckily (and by design), IceWarp is completely independent from big tech ecosystems, meaning it can offer users full data ownership and privacy that no mega-conglomerate can touch.
Price Comparison
For 100 users, the average TCO with MS Exchange is $13,767, compared to only $4,464 with IceWarp. Check out the full breakdown below:
This comparison makes one thing clear: IceWarp is a cost-efficient alternative to MS Exchange. In part, this is made possible by IceWarp’s flexible feature selection—you only pay for what you actually use.
While MS Exchange forces users to buy the whole package, IceWarp users enjoy the “pick and choose” approach, allowing them to save money by avoiding unnecessary tools or features.
Replace MS Exchange with IceWarp
There’s no other way to say it: MS Exchange is DOA. But IceWarp is here to solve its security concerns, while also providing more and better collaboration tools, with Cloud, on-prem, and hybrid options.
Plus, IceWarp’s seamless migration process, with zero downtimes, takes the headache and worry out of making the switch. Stop paying for an outdated and insecure business email, and escape from Microsoft’s other, more expensive tools.
