Hi Greg Taylor - EXCHANGE
Thanks for your clarification on the sign-in report (ActiveSync). I am however confused by the wording in a Conditional Access policy which I would like to use to now block Legacy Auth EAS (Step 4 in the EXO flow). I understand the AAD team responsible for the CA policies is not the same as the AAD team responsible for the sign-ins report and so things might need to catch up, but for clarification. If the policy were configured like this, would only LegAuth ActiveSync be blocked and would IMAP,POP3 Etc also be blocked too? (Assuming the grant access control is set to "Block" in the policy):
Would the "Apply policy only to supported platforms" ONLY apply to ActiveSync Modern Auth clients? Shouldn't there be the option to apply the policy to "supported ActiveSync platforms" in addition as well as, not exclusively?
I think this is where I get confused. Perhaps an example of when I would check the "Apply policy only to supported platforms" option, might help.
