Microsoft Volume Licensing Service Centre is currently undergoing maintenance as part of a series of enhancements to improve the licensing management experience for partners and customers. “Microsoft is upgrading online experience based on partner and customer feedback, which’ll create a single portal to manage all Volume Licensing agreements and IDs, download product keys, and access Software Assurance benefits. This experience’ll also improve administrative management and offer greater flexibility with streamlined registration and permission management. Currently, additional tool functionality including eAgreements and Explore.MS are also impacted by this maintenance. While VLSC is undergoing scheduled maintenance, please visit the Product Activation Call Centres for assistance activating your product,” revealed.
