Hello! Have question about EWS decommission and MTO. As I understand from this change MC1446796 - Migrate Free/Busy, MailTips, and Calendar Sharing before EWS deprecation, need to migrate cross-tenant policies. Did not find specifically stated that this is also needed to be done on Multi tenant organization set up. From Provided powershell commands see that there is MTO using Free/Busy. Did not find anywere clearly stated that MTO is impacted.
