It seems like this problem is not related to the TB version 140 or 148, but due to a change on Microsoft side, not allowing older versions of EAS than current 16.1 version: https://office365itpros.com/2025/12/16/exchange-activesync-161/

Reading this article, I wonder if EAS is the best approach, it seems like there is a new API called "Outlook Mobile", but not sure if available for Desktop? BR Jan

"I don’t understand why Exchange Online users continue to use EAS clients when they can use Outlook Mobile."
