Is there a way that you can change the name of the voice mail that you get in your exchange inbox from voicemessage.wav to voicemessage(time/date).wav?
I know that in your inbox you can see the time stamp, but if you download them and dont rename them, they would all be the same filename essentially.
This sounds like it may be an exchange change.
BTW Exchange is off-box
Weird request, I know, but those customers......
