Starting on October 1, 2024, the EOS of M365 E3/E5 and O365 E1/E3/E5 Ent SKUs with Teams will be technically enforced. This means that M365 E3/E5 and O365 E1/E3/E5 Ent SKUs with Teams will be removed from CSP price lists. After October 1, 2024, all net new purchases of these end-of-sale (EOS) SKUs will no longer be possible. For existing customers, the Microsoft 365/Office 365 Enterprise SKUs with Teams remain available for the same scenarios as before the end-of-sale date. Existing CSP customers can continue to use, renew, add licenses, and upgrade their existing suites with Teams. They'll also now have the other SKU options for M365/O365 Enterprise SKUs without Teams.
