We are setup using Unity for Voicemail. We also have a Blacberry Server tosupport our Blacberry Cellphones. We have three users who are unable to open the voicemails forwarded to their Blackberries. When they are asked for their Unity Voicemail Password and number to call back to they receive the following error code: 80004005 Unable to change number. Any one run across this before? We have basically tried everything including deleting their Unity and Blackberry accounts and wiping and resetting their phones. Thanks!
