Buy Exchange Server 2010 CAL – Client Access License for legacy systems at a low price

If you’re still running Exchange Server 2010, you’ll need a Client Access License (CAL) for every user or device that accesses the Exchange Server. The Exchange Server 2010 CAL is the right access license for this oldest version of Exchange Server still in use—it’s affordable, verified, and suitable for use in legacy environments. At Lizenzindustrie, you’ll receive your CALs immediately via email—legally compliant and at an affordable price.

Important Note: Since Microsoft stopped providing security updates for Exchange Server 2010 in October 2020, we recommend operating it exclusively in fully isolated network environments. For all other use cases, we strongly recommend migrating to at least Exchange Server 2016 or Exchange Server 2019.

Recommendation: Since newer CAL versions are also valid for older Exchange versions, we recommend purchasing a newer CAL version even for existing Exchange 2010 infrastructures. An Exchange Server 2016 CAL or Exchange Server 2019 CAL is also valid for Exchange Server 2010 and simultaneously enables future migration without the need to purchase a new CAL.

Standard CAL or Enterprise CAL—which is the right choice?

Exchange Server 2010 CALs are available in two versions:

Exchange Server 2010 Standard CAL – The Standard CAL grants access to all basic Exchange 2010 features: email, calendar, contacts, tasks, Outlook Web App, ActiveSync for mobile devices, and IMAP/POP3 access. For most employees in standard work environments, the Standard CAL is perfectly sufficient and the more cost-effective choice.

Exchange Server 2010 Enterprise CAL – The Enterprise CAL is an extension license to the Standard CAL and requires it as a prerequisite. Enterprise CALs expand the feature set to include archive mailboxes for unlimited email archiving, advanced compliance features such as legal hold, unified messaging for voicemail integration, and advanced eDiscovery capabilities. Enterprise CALs are primarily relevant for users in regulated industries.

Exchange Server 2010 CAL – Compatibility with Other Exchange Versions

• ✔ Exchange Server 2010
• ✔ All older Exchange Server versions
• ✗ Exchange Server 2013 – requires an Exchange Server 2013 CAL or newer
• ✗ Exchange Server 2016 – requires an Exchange Server 2016 CAL or newer
• ✗ Exchange Server 2019 – requires an Exchange Server 2019 CAL

Recommendation: More future-proof with a newer CAL version

Since newer Exchange Server CALs are also valid for older versions, it’s worth considering more recent CAL versions even for existing Exchange 2010 infrastructures:

• Exchange Server 2016 CAL – Also valid for Exchange Server 2010. The most affordable future-proof option up to Exchange Server 2016.
• Exchange Server 2019 CAL – Also valid for Exchange Server 2010. The best and most future-proof choice for companies planning to migrate to Exchange Server 2019 in the long term.
