Hi, Thomas.
Thanks for posting. However, this is an English forum. It will be appreciated if you can communicate with English so that we can understand it better.
I used a translation tool and please let me know if I misunderstood anything.
According to the result of translation, I suppose your issue is:
You got the error message while setting up your account on Win10 Outlook clients, other mailboxes in your organization are not affected.
Let me know if I misunderstood anything.
Before we troubleshoot the issue, could you provide some specific information about your issue?
- What’s your Exchange version? Are you in a Dag or hybrid environment? And which version of Outlook are you using? Make sure it’s the newest version if allowed.
- Just to confirm, is that you see the error information while setting up profile or opening Outlook?
- Can you find any error messages in the event logs? Please provide screenshots or text information if possible.
- Can you try running the test e-mail configuration for your mailbox and other mailboxes? Is there any difference?
You can also use the exrca tool.
Below is how can you perform the process:
- Use the test E-mail Autoconfiguration on Outlook
Ctrl+Right Click on the Outlook icon,select Test E-mail AutoConfiguration
Input your E-mail address and Password,choose Use AutoDiscover,then click test.
If you get information like these in the log tag,then the autodiscover service is working properly.
- Use the exrca(Microsoft Exchange Remote Connectivity Analyzer)
It is an online tool for users to test if their exchange services are set up correctly.
The URL is https://testconnectivity.microsoft.com/tests/Ola/input.
You need to fill in the blanks to perform the test.
Here are some suggestions:
- Would you mind testing with other versions of Outlook and see if you will get same issue?
- Please try to create a new user mailbox and connect it with Outlook. If no issue exists,
You can try exporting your mailbox contents and importing them into the new mailbox.
Here is official guidance for your reference:
