exchange end of support

About this tag
Exchange end of support refers to the October 14, 2025, cutoff for Exchange Server 2016 and 2019, after which Microsoft will no longer provide security updates or technical support. Organizations still running these on-premises versions face escalating risks and limited upgrade paths. Microsoft urges immediate migration to Exchange Online or the new Exchange Server Subscription Edition (SE). The April 2025 hotfix updates are the final patches before end of support, and hybrid enforcement windows begin soon. IT administrators must act now to avoid security vulnerabilities and compliance issues. This tag covers migration planning, hotfix details, and the broader impact of Microsoft product end-of-support dates.
