Hi everyone, I had multimedia messaging working on Exchange 2000 SP3, XPpro and Outlook 2002. I not definite but I'm the latest thing that was upgraded was mediaplayer9 and was wondering if anyone has this combination and working? I am able to record a multimedia message but unable to playback using the integrated html multimedia function play button, I will get an error message as such: (Error Details - windows Media Player cannot play the file because the specified protocol is not supported. In the Open URL dialog, tyrp opening the file using a different transport protocol (for example, "http:" or "rtsp:"). Is there a hack for this? I have exhausted my resources, Technet, MS Kbase, Google, newsgroup search, any idears? The only workaround so far is to just right-mouse click the attached asf file and click open....so the mediaplayer opens in another window inwhich defeats the purpose of Microsoft Exchange Multimedia Control Any help would be greatly appreciated.
