How many messages can be stored in a subscriber's mailbox?
This is determined by the configuration of the Exchange message store.
What is the maximum total number of minutes of messages that can be stored in a single voice mailbox?
This depends on the size limit set by Exchange and the audio compression codec used for voice message storage.
Are users given any notification that these limits have almost been reached?
If mailbox size reaches the warning limit, Exchange provides email notification and Unity warns the subscriber when checking messages over the phone.
How many Mbytes of disk space are required for each hour of voice storage?
This depends on the compression/decompression (CoDec) scheme used. The default is 8kb/sec but this can be changed with the SetRecordFormat.exe utility.
