[German]At the turn of the year 2022/2023, Microsoft has deactivated Basic Authentication for Exchange Online. This forced Thunderbird users into connection issues with mail servers via IMAP. Thunderbird reports that the user is authenticated (via oAuth2) but is not connected. But there is a workaround for Thunderbird. Addendum: It seems that Microsoft has fixed the issue.
[German]When using Microsoft Teams, administrators should make sure that no special characters appear in the profile names. This can lead to strange errors. The Teams client may refuse to start if, for example, a round bracket appears in the profile name. Frank Carius came across the problem at a customer in mid-December 2022 and then analyzed the whole thing. And there is a second find from mid-December 2022 in the form of a post in the Microsoft Techcommunity. In both cases, there are tickets at Microsoft, but they relate to different versions of the MS Teams app. Here is a brief overview of these cases, where I am not yet aware of any solutions from Microsoft (only workarounds that users have found).
[German]At the beginning of the year 2023, I am once again bringing up a topic that I already addressed here on the blog in 2015 and in January 2021. It's about the Microsoft Outlook app, which is available for Android and iOS devices and, in my opinion, is widely used. In the corporate environment, however, those responsible are sailing in risky waters, because this app transfers login data and mails to the Microsoft Cloud, so that they can be analyzed there. In the EU Parliament, the use was prohibited and I had pointed out the issue again in 2021. The issue has now come to my attention again because Baden-Württemberg's data protection commissioner has subjected the app to an analysis. It also came out that the app transfers data to the cloud.
That's what I wish all blog readers and above all health and optimism in these times. The year 2022 is over, and now 2023 is upon us, whatever the new year may bring.
