Thanks for this! A very helpful report. I'm glad you flagged the earlier deadline for the kiosk plans, in particular.

Does Microsoft have a list of its own application versions that use EWS, and that Microsoft still sells and supports? For example, System Center Service Manager appears likely to be cut off in June 2026:

SCSM use EWS which will must change to microsoft Graph before retired - Microsoft Q&A

The only Microsoft answer to that question so far is from a bot, but its generic answer does not work for Microsoft-owned software.

Thanks again for the information.

Can confirm that the team responsible for SCSM functionality that uses EWS is aware of the deprecation. Sorry I got no details as far as what / when / how they plan to solve this but I did get a confirmation that they are aware.
