You can use Skype for Business to set up voicemail for a group of people. The steps involved in setting up group voicemail is almost exactly the same as that for individual Skype for Business accounts.
1. Login to https://portal.joinvia.com then select Voicemail > Create.
2. Enter two existing email addresses. Please ensure BOTH addresses entered (they can be the same) are VALID email addresses.
We recommend using a distribution group within your email system (usually free of charge) as the voicemail SIP address.
Please ensure this distribution group is enabled BEFORE creating the group voicemail.
3. You'll then receive a welcome email to the email address you entered above. Set the password as you would a standard account.
4. Sign into Skype for Business using this new account, press and hold "1" on the keypad and follow the instructions.
