1. This may cause of your hosting side issue, like IP black list of random users, suggested to you please White List IPs from ISP.
2. Try to disable antivirus / windows security
3. Safe password in outlook windows when its again in password window.
4. there might be any / some users they might block domain for all users due to bulk email sending, virus infected emails etc...
5. If you are cPanel hosted domain try to OFF "hulk brute force" as per cPanel [ When cPHulk blocks an IP address or account, it does not identify itself as the source of the block. Instead, the login page displays the following warning message: The login is invalid.]

Hi @SevenThai ,

Outlook client keeps asking for passwords is a relatively common question with multiple possible causes.

In my experience, for the case of connecting an on-premises mailbox, you can generally try modifying the registry of Outlook client first to see if there are any changes:

1.Locate this location in Registry Editor：

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover

2.Create a DWORD (30-bit) value for ExcludeExplicitO365Endpoint and change the value to "1" to enable it.

3.Restart the computer and log in to the Outlook client.

 （Kindly note: To avoid incorrect operation, it is recommended that you back up the registry before doing so.）

If the above method doesn't work, please feel free to reply so we can find other solutions. Thank you for your understanding.
