Hey everyone,

I have gotten this window on my laptop at work, and I would really appreciate it if someone here could please write me an explanation of what it means. The window is in German so you might have to translate it. Please note the email written (hidden in black)

is not mine.

Thank you very much! Screenshot_20260112_153353_com.android.gallery3d

Hi @worod,

Thank you for posting your question in the Microsoft Q&A forum. I noticed that your post is in the en-us channel and the description is in English, so I’ll continue in English to keep things consistent.

Based on my research, the dialog box you’re seeing is a security prompt from Microsoft Outlook. It usually appears when someone, or a script or application is trying to configure email account settings through an external website. The message is essentially a warning that your account has been redirected to a website for configuration, and you should only allow this if you recognize and trust the source.

You can find more details here: Suppress AutoDiscover redirect warning in Outlook - Outlook | Microsoft Learn

In most cases, if you’re certain that the server belongs to your organization, it’s safe to click “Allow” (Zulassen). However, if the dialog shows an email address that isn’t yours, don’t rush to click Allow (Zulassen). This situation can occur for several reasons, such as a shared calendar in Outlook that requires updated configuration, an old account from a former employee that Outlook still remembers, or possibly other scenarios that need verification.

At this point, I recommend contacting your company’s IT department as soon as possible. They have the authority to verify whether the AutoDiscover server is legitimate, ensure that DNS and SSL configurations are correct, and then implement a long-term solution to prevent this warning from appearing again.

I hope this information helps clarify the situation and gives you a clear next step to consider. If you have any updates or further questions, please don’t hesitate to leave a comment under this post so I can assist you further.

Thank you for your time, and I look forward to your response!

Thank you so much for your reply!

Could you please tell me what possible rights would have the person had if I had clicked on (Zulassen)?

I have already sent this to my IT service at work, they told me it was weird but didn't explain further yet. I am not sure if they would tell me what's happening. That's why I am asking for help here.

Hi @worod,

Thank you so much for your follow-up question! Based on my research, here’s what would happen if you clicked “Zulassen” (Allow):

If the redirected site is legitimate (for example, your company’s official Exchange or Microsoft 365 Autodiscover endpoint), then:

It would only provide Outlook with the correct technical connection settings so your client can reach the right mail server.

No additional mailbox permissions or access beyond your normal account rights would be granted.

If the redirected site is malicious or not under your organization’s control, then by clicking Allow you would effectively:

Permit the site to supply fake server settings, potentially redirecting your Outlook client to an attacker-controlled server. This could lead to credential capture or interception of your email traffic.

Establish persistent trust for that endpoint, making future redirections harder to detect and increasing the risk of man-in-the-middle style attacks.

Since you’ve already contacted your IT team, I strongly recommend following up with them again to confirm whether the redirect was expected and safe. They may be able to check logs or validate the endpoint for you.

Thank you again for raising this concern, and I’d love to hear any updates from you. Please feel free to keep me posted or ask additional questions if needed.
