I updated from 7.2.2 FOSS to 7.2.3_GA_2872.UBUNTU10_64 UBUNTU10_64 FOSS edition. My IE 10 users on Windows 7 can't use the web interface. They can log in, but most of the AJAX doesn't work.
According to this post, IE 10 support was added in 7.2.2: Access my Zimbra account via Internet Explorer 10 in Windows 8
What's the word on IE 10 support in 7.2.3? Is there anything I can do to troubleshoot this, aside from having users use the "standard" non-AJAX interface or another browser?
