[German]Microsoft has already published a support article on June 19, 2023, which deals with a problem under Microsoft 365 in connection with Outlook. Outlook starts extremely slowly in certain situations and gets stuck in the startup logo. The cause is probably an unexpected switch from REST to MAPI.
[German]Quick note for administrators who use Exchange Online as an SMTP relay to send bulk email. Microsoft is adjusting the requirements for using SMTP relay functionality accordingly as of November 1, 2023. The company made the announcement in a June 19, 2023 blog post.
[German]It's a little bit of fun that shows that Microsoft doesn't really have a handle on its AI solution ChatGPT (yet). What only Chinese bot farms have been able to do so far, could also be done with ChatGPT (or Google's Bard): Let em search valid product keys for activating Windows 10, Windows 11 (and possibly Office) from the Internet. Someone just tried this and it seems to have worked.
[German]It was hacker attacks that brought Microsoft cloud services to their knees for hours on and off since June 5, 2023. My reports here on the blog that a hacktivist group called "Anonymous Sudan" claimed responsibility didn't turn out to be an airhead at the end of the day. I had cited information on a Post Incident Report For Microsoft 365 over the weekend that described some details and countermeasures. But there is also a publicly available blog post that confirms these attacks and gives details.

[German]Quick question to my blog readers who are using Microsoft 365/Office in the Current Channel. Are there any complaints that multi-page output is not possible when printing tasks (but not from calendars or mails)? I just received a user report, which I briefly introduce below.
[German]To secure Windows, Microsoft recommends Windows Defender Application Control in enterprise environments. The last few days, however, this feature seems to cause issues due to an definition update. I have received reports that users "suddenly" could neither open files nor run programs. Even accessing network drives or opening Internet pages was no longer possible. They were told that the app was blocked by Windows Defender Application Control. It looks like the Microsoft Defender Security Intelligence Update version 1.391.1503.0 is the cause.
[German]Since June 5, 2023, there have been repeated problems with the availability of the Microsoft cloud and the services offered there. I had speculated in my blog posts that there might be an attack behind it, especially since a hacktivist group Anoynmous Sudan had claimed that. From Microsoft circles it was said uniso "nothing known". Now I have a Post Incident Report For Microsoft 365, that indicates, that there must have been DDoS attacks on Microsoft's cloud.
[German]Short addendum from this week. I received a tip that Microsoft Outlook 365 has been constantly corrupting Office files – and probably also PDF documents – since April 2023. If you don't have a backup, you may lose attachments – deadly if you have to archive mails including attachments. Microsoft's assumption that this is related to a Windows update and was fixed in June 2023 on patchday is unfortunately incorrect. Here is an overview of the problem.
[German]The days I noticed some comments in my German blog that users report issues with Firefox. The possible cause is the activation of DNS over HTTPS (DoH) and use of the Cloudflare DNS server, as one user told me.
