Before anyone states the obvious I know Windows 10 is not out yet and apps might not work properly.
I am currently testing Jabber and WebEx (T29.8) on several devices in my organization in preparation for next year. Jabber functions properly once past SSO. However WebEx is throwing an account error. I can use the same Jabber/WebEx account on a Win7 machine without issue.
Has anyone else started testing WebEx on Windows Tech Preview
Technical support does not monitor this board, as it is geared more toward developers. The technical support team would be most likely to have attempted this, and might have heard a date or version where support for Windows 10 is planned.
