Basic Authentication Deprecation in Exchange Online – September 2022 Update

dz890Regarding the Samsung Mail app, in my organization, some Samsung users were already using modern auth with that (check Enterprise Applications in Azure). The few that weren't (so they were using basic auth) had selected "Corporate"/"Exchange" as the account type when they set up email. They just needed to delete that account from Samsung Mail and add it again using "Office 365" as the account type. That switched them to modern auth (I did this with those users back around May and they no longer show up in the basic auth client app types in the https://docs.microsoft.com/en-us/azure/active-directory/reports-monitoring/concept-sign-ins#where-can-you-find-it-in-the-azure-portal). One user had a Galaxy S7 on Android 8, so it has supported modern auth in Samsung Mail for a while now. On other Android phones, the Gmail app also supports modern auth (when setting up the Exchange account, use automatic setup, not manual, and look for the Microsoft sign-in web page instead of just a password prompt). Just like humbeglez and Greg Taylor said, this uses ActiveSync with modern auth, so it won't get disabled by the basic auth retirement.
