Exchange Unified Messaging Online migration support
In reference to the announcement on February 8, 2019, Microsoft is retiring the Exchange Unified Messaging Online (ExchUMO) service by February 2020. This article offers a summary of what affected customers should know and do to plan for their business continuity.
ExchUMO is deployed by customers for voicemail, Auto Attendant, and/or fax integration services. Microsoft plans to help these customers migrate to its cloud-based services that support thousands of customers already on Skype for Business Online and Microsoft Teams.
Voicemail is primarily a Microsoft-driven migration; admin involvement and/or investment might be required for a subset of customers. Auto Attendant is an admin-driven migration; you will need to re-create the existing ExchUMO Auto Attendant trees in the Cloud Auto Attendant cloud service. Customers who are consuming any of the ExchUMO features with a third-party PBX will not be migrated to Skype cloud services because they do not support third-party PBX systems. A retirement plan for third-party support was announced last year in this blog, and customers in this deployment model can migrate their users to one of Microsoft’s Unified Communications platforms/services or acquire a third-party voicemail and/or auto attendant solution for these users. Fax integration is not supported in the cloud-based services; customers will need to migrate to a third-party solution.
Who is affected?
Customers who are consuming any of the following features from Exchange Unified Messaging Online service are affected:
- Voicemail service
- Auto Attendant service
- Fax integration
Customers who are using any of the Exchange Server on-premises with Unified Messaging are not affected.

Migration plan overview
Microsoft has identified various customer deployments that are consuming features from ExchUMO and will be helping customers migrate based on the following plan.
|Customers who are ready to migrate

|March – May 2019||Examples:
|Customers with prerequisites
Features to migrate:
|May – December 2019||Examples:
|Customers who require admin involvement & customer investment
Features to migrate:
|By February 2020||Examples:
Familiarize yourself with the blog announcement and this article to plan a smooth migration for your users. See Check Skype for Business voicemail and options for details on the Cloud Voicemail capabilities.
Establish a Skype for Business hybrid topology
If you do not have a Skype for Business hybrid topology established, you need to do that to enable a smooth migration of your voicemail users. See Configure Skype for Business hybrid for more details.
You do not need to migrate your users to online for the voicemail service migration. However, for on-premises users to leverage the cloud-based voicemail service, a hybrid topology is must be established.
Plan your Auto Attendant migration
Admins can start migrating their Auto Attendants from ExchUMO to the Cloud Auto Attendant at any time. See Set up a Cloud auto attendant for more details. Microsoft plans to deliver additional Auto Attendant capabilities that customers consider critical for their migration by March 2019. Admins should evaluate the feature set and migrate their Auto Attendant instances accordingly. For feature-list comparison, see the ExchUMO and Azure cloud-based services feature matrix.
Plan for your voicemail post-migration validation and testing
Voicemail migration is Microsoft driven; Admins are not required to do anything, given that the pre-requisite hybrid topology is established. Microsoft will perform the required validation and testing to make sure users’ voicemail migration is not disrupted; however, admins are encouraged to perform testing and validation on their side. See Suggested test plan and post-migration validation for admins for a recommended test plan.
Lync Server 2010 is not supported. If you are in a 2010 server deployment, you should plan a server upgrade or consider migrating your users to Microsoft Teams or Skype for Business Online.
Monitor the Admin Notification Center
Look out for a notification in the Admin Notification Center with further details and timeline regarding your users' voicemail migration. Notifications will be sent at least 30 days before your migration period.
If you received a notification with your users’ migration timeline and would like to postpone your migration for a business-critical reason, you can do so by contacting Microsoft Support. Note that you cannot postpone your migration beyond the retirement date, February 2020. For customers who may have more questions, please contact your account team or Microsoft Support. Customers already using Office 365 can submit a support case through the Office 365 Admin portal.
Consider opting in for a planned migration
You can opt in for a planned Voicemail service migration to CVM. Before opting in, review the details of this article, especially the following sections:
- Migration steps (this section)
- ExchUMO and Azure cloud-based services feature matrix

Note that by opting-in for a managed migration you will not be receiving a pre-migration 30-days notification in the Microsoft 365 admin portal message center.
To opt-in for a planned migration, send an email request to firstname.lastname@example.org, using your administrator's email address, with the following information:
Preferred date (Tuesdays): migration waves are executed every Tuesday. Please select a date on a Tuesday that is not beyond 12/3/2019.
Tenant ID: 32 characters number in this format 0046728c-688a-4472-a38f-098fec60ac6x. You can find your tenant ID in the Microsoft 365 admin portal under Azure Active Directory, or by executing the following PowerShell cmdlet:
Get-CsTenant | Select ObjectId
You will receive an email confirmation once your tenant is successfully migrated.

Suggested test plan and post-migration validation for admins
To validate that your users have been migrated to Cloud Voicemail, simply leave a voicemail to a user and check the message body in Outlook, Cloud Voicemail messages have an additional footer that reads:
Thank you for using Transcription! If you don't see a transcript above, it's because the audio quality was not clear enough to transcribe.
When testing voicemail functionality after your users have been migrated, make sure to consider the following scenarios:
- Validate voicemail access across all endpoint types in your organization: apps and IP phones.
- Validate with sample users that the configured personalized greetings are played to callers.
- If your organization has a legal or compliance requirement to disable transcription for users, make sure it is disabled post migration. For more details, see Set up Cloud Voicemail.
- If you have previously configured Exchange VM policies and rules, make sure they are effective.
- Familiarize yourself with the Cloud Voicemail service PowerShell cmdlets for changing user settings.
