We currently have Unity 2.46 and Exchange 5.5 on the same server with which is pentium 3 1 Ghz with 1 gig of memory and a 12 gig HD. We are not running unified messaging. Is there a limitations to the number of voicemail boxes supported before you notice a impact on the system. If so what is the number and where can I find support documentation for that number.<br><br>
