Symptoms
Consider the following scenario:
You have enabled Busy Options feature in a Microsoft Skype for Business Server 2015 environment that has Cumulative Update 2 (Version 6.0.9319.235) or later versions installed.
You enable a user for Microsoft Exchange Unified Messaging (UM) On-Premises.
You move the user's mailbox to Exchange Online.
You enable the user for Exchange UM Online by assigning on-premises hosted voice mail policy.
Note The on-premises attributes for this user are now set as follows:
- ExUmEnabled=False
- HostedVoiceMail=True
In this scenario, you can’t set the BusyOnBusy option to an ActionType of VoicemailOnBusy for this user.
Additionally, you receive the following error message:
PS C:\Users\SfBadmin> Set-CsBusyOptions -Identity "Ken Myer" -ActionType VoicemailOnBusy
Set-CsBusyOptions : Voicemail is not enabled for Identity "Ken Myer".
