mariozlo LRS-sunrise2445 Mairie38 We do not really discuss / publish pricing on this blog (I have been with this blog since day 1 and I don't recall seeing pricing ever, LOL). ScottSchnoll can correct me if needed, but for pricing, please contact your Microsoft rep / business desk (I do not know if pricing for SE has been finalized yet).

For other possible combinations (and what the most cost-effective way is to get the licenses, you'll need to discuss with your Microsoft rep / business desk. We do not have a comprehensive list of all Microsoft 365 licensing options.
