The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This document describes the procedure for the integration of Microsoft Office 365 with Cisco Unity Connection (CUC).
Cisco recommends that you have knowledge of Cisco Unity Connection (CUC), Release 8.x and later.
The information in this document is based on CUC Release 8.x and later.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
In the Display Name field, enter a Display Name in order to identify this UM Service.
In the Proxy Server(Address:Port) field, enter a Proxy Server address if the Unity Connection server cannot access the Office 365 servers in the cloud.
In the Hosted Exchange Servers section, choose Search for Hosted Exchange Servers. This is mandatory. 'Specify the Hosted Exchange Server' is not supported since the IP Address or the Hostname of the server in the cloud is not known.
In the Unified Messaging Service field, select the newly created service from the drop-down list.
In the User This Email Address field, enter the email address of the Office 365 mailbox. This email address can be either user@<OrganizationDomainName>.onmicrosoft.com or user@<OrganizationDomainName>.com based on the deployment model.
In the Display Name drop-down list, choose Voice Mail User COS. This is the default Class of Service (CoS) associated with all users. If users are associated with a different CoS, choose the appropriate selection.
Check the Allow Users to Access Voicemail Using and IMAP Client and/or Single Inbox checkbox.
Select the Active Directory DNS Domain Name
The Domain name is the one that is provided by Office 365. It can be in the form of <name>.onmicrosoft.com. In this example, the mailboxes are in the calobgl.onmicrosoft.com domain.
In the Unified Messaging Services configuration, use either calobgl.onmicrosoft.com or outlook.office365.com as the domain name. Either one can work fine. The only difference is in the Autodiscover URL that Unity Connection uses in order to discover the mailbox.
There are no steps to troubleshoot this configuration.
There is currently no verification procedure available for this configuration.
