Enabling protected voicemail in your organization

When someone leaves a voicemail message for a user in your organization, the voicemail is delivered to the user's mailbox as an email message attachment. Using mail flow rules to apply message encryption, you can prevent those voicemail messages from being forwarded to other recipients. When you enable protected voicemail, users can listen to protected voicemail messages by calling into their voicemail mailbox or by opening the message in Outlook, Outlook on the web, or in Outlook for Android or iOS. Protected voicemail messages can't be opened in Skype for Business or Microsoft Teams.

For more information about message encryption, see Email encryption.

To set up protected voicemail, do the following:

1. Go to https://admin.microsoft.com and sign in using an account with global administrator permissions.
2. Select Show all and then go to Admin centers > Exchange.
3. In the Exchange Admin Center, select Mail flow > Rules.
4. Select +Add, and then select Apply Office 365 Message Encryption and rights protection to messages.
5. Provide a name for the new mail flow rule and then under Apply this rule if, select The message properties > Include the message type > Voice mail. Select OK.
6. Under Do the following, select Apply Office 365 Message Encryption and rights protection to the message with and then select Select one. Under RMS template, select Do not forward. Select OK and then Save.

   Note

   If the RMS template list is empty, you need to set up Message Encryption. For more information about setting up Message Encryption, see the following articles:

Setting voicemail policies in your organization

Warning

For Skype for Business customers, disabling voicemail through a Microsoft Teams calling policy might also disable the voicemail service for your Skype for Business users.

Voicemail transcription is enabled by default and transcription profanity masking is disabled by default for all organizations and users; however, you can control them by using the Set-CsOnlineVoicemailPolicy and Grant-CsOnlineVoicemailPolicy cmdlets.

Voicemail messages received by users in your organization are transcribed in the region where your Microsoft 365 or Office 365 organization is hosted. The region where your tenant is hosted might not be the same region where the user receiving the voicemail message is located. To view the region where your tenant is hosted, go to the Organization profile page and then click View details next to Data location.

Important

You can't create a new policy instance for transcription and transcription profanity masking using the New-CsOnlineVoiceMailPolicy cmdlet, and you can't remove an existing policy instance using the Remove-CsOnlineVoiceMailPolicy cmdlet.

You can manage the transcription settings for your users using voicemail policies. To see all available voicemail policy instances, you can use the Get-CsOnlineVoicemailPolicy cmdlet.
