We are trying to send voicemails from one account to multiple users that share a line.
So when a call comes in to 6XXX extension and the call goes to voicemail. After it goes to voicemail we are wanting all of the users(5) who share that line to get the voicemails in their Outlook inbox also. We tried to use the relay option to a distribution group and that did not work. Any ideas on how to do this in Unity instead of creating a rule in Outlook would be great.
not a problem - setup a call handler with extension 6xxx that handles inbound calls forwarded from that number, create a public distribution list and add the 5 users to it and then set that call handler up to leave messages for the distribution list.
If you're talking about Unity Connection (which I assume you are - 8.5 is not a Unity version) you can also look into dispatch messages with this technique which allows you to have the first person of those 5 that "take" the message then own it (i.e. it's removed from the other user's mailbox when they do that). This is designed for service dispatch like scenarios which may be of interest to you.
