EMERGENCY SECURITY PATCH
We have released Zimbra Version 10.1.14 to address a critical issue in Version 10.1.13 that impacts IMAP synchronization across multi-server Zimbra environments, causing incorrect message display and synchronization failures.
For complete details and implementation guidance, please refer to our release notes:
Customers on Version 10.1.13
Patch Security Severity: Low
Deployment Risk: Low
We strongly encourage all customers with a high IMAP user base who have upgraded to Version 10.1.13 to upgrade to Zimbra 10.1.14 immediately. Customers on Version 10.1.13 with a low IMAP usage pattern may continue using the current version and wait for the upcoming Version 10.1.15.
Customers on Version 10.1.12 or earlier
Patch Security Severity: High
Deployment Risk: Low
Customers currently on Patch Version 10.1.12 or earlier are recommended to upgrade directly to Version 10.1.14 for improved stability and fixes.
This new patch version also resolved slowdown issues when switching to the Zimbra user post-upgrade to Version 10.1.13. User switching is now significantly faster and more responsive through optimized license data caching.
End of Life Notice: Zimbra 10.0
Zimbra 10.0 will reach End of Life on December 31, 2025. Customers using this version are advised to plan their upgrade/migration to the 10.1 version (our current supported version) to ensure continued security updates and access to the latest features. For assistance during this transition, our support team is available to address any inquiries.
