Hi,
Seems something is wrong with the Check Name.
Please first try to create a new mail profile in Control Panel and reconfigure your email account in the new profile to check the result. See:

In addition, this issue may occur when the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders registry key does not contain all of the required data. Specifically, these problems occur if the
AppData string value is missing from this registry key.
NOTE: The \User Shell Folders key also contains a string value called
Local AppDatawhich is different from the value called AppData. The value that causes this problem (if it is missing) is the
AppData value.
To resolve this issue, import the User Shell Folders registry key from a working Windows User Profile. For more information, please refer:

Hope this helps.
