When users synchronize from Azure to Webex Control Hub using SCIM, our current support is limited in terms of attributes (link shared below). Certain customers may require the inclusion of extra attributes to align with their business needs. While the Department attribute can be added and synchronized, however Cisco BU does not currently provide support for this addition. In the future, it would be beneficial to incorporate this feature to assist customers seeking additional attributes beyond what is presently available.
