I have an environment where all PC's have Office 2007 with all the updates, and a Toshiba CTX phone system. Almost all the PC's have the various Toshiba apps installed (Oaisys Netphone 5.1 build 34, Stratagy ES Outlook Client, unknown version, installer is called "OutlookClientVistaReady.exe", and Stratagy ES Fax Printer Driver v3.1.0). Many of the PC's have stability issues with Office. I have other locations with similar installations, with the exception of the Toshiba apps, that have no stability issues. I really think the Toshiba app is causing these problems, but I have been unable to find any solid information on the compatibility of these applications with regards to Office 2007, although I found one post somewhere on the internet saying that the plug-ins where not compatible with Office 2007. Does anyone have any definitive compatibility information, ideally with some information I can reference?
