Through the translation, I learned that your problem here is Samsung Android devices cannot connect to your Exchange server. If I have missed something, please feel free to let me know.
Here are some possible solutions:
- Verify that the account settings are correct.
- Remove the Outlook account and then re-add it as a Microsoft Exchange account.
- If you’re prompted for IMAP/POP3, tap the ? icon at the top and select Change account provider. This should allow you to choose Exchange on the next screen.
- Check if the Exchange Online mailbox server that supports the connection is available. Reference: https://support.microsoft.com/en-us/office/set-up-email-in-android-email-app-71147974-7aca-491b-978a-ab15e360434c
- If the mobile phone is unable to contact the Exchange server automatically through the Autodiscover service, you’ll need to set up the mobile phone manually. Manual setup requires the user’s email address and password, as well as the Exchange ActiveSync server name.
I hope this helps. Let me know if you have any other questions.
