[English<\/a>]Kurzer Hinweis f\u00fcr Administratoren, die Apple-Ger\u00e4te mit \u00e4lteren iOS-Versionen in einer Exchange Online-Umgebung verwalten. K\u00fcmmert euch darum, dass diese Ger\u00e4te f\u00fcr Modern Authentication vorbereitet sind, sonst gibt es bald Kommunikationsprobleme. Sp\u00e4testens am 1.

\"\"Das Ganze ist irgendwie ungl\u00fccklich gelaufen und sollte l\u00e4ngst vom Tisch sein. Ich hatte 2020 bereits im Blog-Beitrag Microsoft Office 365-Anmeldung wird \u00fcberarbeitet<\/a> gemeldet, dass Microsoft es ab dem 13. Oktober 2020 gravierende \u00c4nderungen bei der Exchange Online-Basisauthentifizierung gebe (kickt Outlook 2010 aus Exchange Online). Wegen der Coronavirus-Pandemie wurde das Vorhaben dann aber verschoben, siehe den Artikel Exchange Online: Abschaltung Basic Authentication in 2021<\/a>. Aber in 2022 will Microsoft was \u00e4ndern.<\/p>\n

\"Office365<\/a><\/p>\n

Die Tage bin ich auf obigen Tweet<\/a> gesto\u00dfen, der daran erinnert, dass Apple Mail Clients ein Upgrade ben\u00f6tigen, um die Modern Authentication zu unterst\u00fctzten. Die Details lassen sich in diesem Blog-Beitrag<\/a> nachlesen. Ab Oktober 2022 d\u00fcrfte die Basic Authentication in allen Exchange Online Tenants abgeschaltet werden.<\/p>\n

Der Poster schreibt hier<\/a>, dass er am 12. September die Message-Center-Benachrichtigungen MC284549 und MC284559 erhalten habe. Diese informierten ihn dar\u00fcber, dass Microsoft die Basisauthentifizierung f\u00fcr POP3, IMAP4, Remote PowerShell, Exchange Web Services (EWS), das Offline-Adressbuch (OAB), Exchange ActiveSync (EAS), SMTP AUTH und MAPI deaktiviert habe.<\/p>\n

Noch funktioniere alles. Mit der Entscheidung von Microsoft, dass diese \"ab dem 1. Oktober 2022 die Basisauthentifizierung in allen Tenants unabh\u00e4ngig von der Nutzung dauerhaft deaktivieren werden\", kommen die Dinge wohl in den Fluss. Sp\u00e4testens In einem Jahr wird die Basisauthentifizierung f\u00fcr Exchange Online abgeschaltet, selbst wenn eine Organisation sie aus irgendeinem Grund beibehalten m\u00f6chte. Auf diese Abschaltung sollte man vorbereitet sein, zumal der Vorgang bereits Anfang 2022 f\u00fcr einzelnen Dienste passieren k\u00f6nnte. Details lassen sich in den verlinkten Artikeln nachlesen.<\/p>\n

Erg\u00e4nzung:<\/strong> Martin P. hat mir per Mail folgende Information von Microsoft zukommen lassen.<\/p>\n

Updated September 27, 2021: We have updated the content for additional clarity. Thank you for your feedback.<\/p>\n

We're making some changes to improve the security of your tenant.\u00a0 We announced in 2019 we would be retiring Basic Authentication for legacy protocols, and in early 2021 we announced we would begin to retire Basic Authentication for protocols not being used in tenants, but not disable Basic Authentication for any in-use protocols until further notice.<\/p>\n

Today, we are announcing that, effective October 1, 2022, we will begin to permanently disable Basic Auth in all tenants, regardless of usage (with the exception of SMTP Auth, which can still be re-enabled after that).<\/p>\n

We previously communicated this change via several Message Center posts: MC191153 (Sept. '19), MC204828 (Feb. '20), MC208814 (April '20) and MC237741 (Feb. '21) and you can always read the latest information about our plans to turn off Basic Authentication here.<\/p>\n

Beginning early 2022, as we roll out the changes necessary to support this effort, we are also going to begin disabling Basic Auth for some customers on a short-term and temporary basis.
\nWe selectively pick tenants and disable Basic Auth for all affected protocols except SMTP AUTH for a period of 12-48 hours. After this time, Basic Auth for these protocols will be re-enabled, if the tenant admin has not already re-enabled them using our self-service tools.
\nDuring this time all clients and apps that use Basic Auth in that tenant will be affected, and they will be unable to connect. Any client or app using Modern Auth will not be affected. Users can use alternate clients (for example, Outlook on the Web instead of an older Outlook client that does not support Modern Auth) while they upgrade or reconfigure their client apps.<\/p>\n

How this will affect your organization: If you receive a Message Center post between now and October 2022, informing you that we are going to disable Basic Auth for a protocol due to non-usage, or you get one saying we know you are using Basic Auth, but we intend to proactively disable it for a short period of time, and you don't want us to disable specific protocols, you can use the new self-service feature in the Microsoft 365 admin center to opt-out and request that we leave specific protocols enabled until October 2022. We added this feature to help minimize disruptions as you transition away from using Basic Auth.
\nWe will disable Basic Authentication beginning October 2022, and once that happens, users in your tenant will be unable to access their Exchange Online mailbox using Basic Authentication.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
