Compatibility issues of Kaspersky VPN Secure Connection for Android with mail apps
Microsoft Outlook may return errors when the secure connection is enabled in Kaspersky VPN Secure Connection due to mail server configuration issues.
To eliminate the error, try connecting via another country (you may need to try several countries). If this does not help, disable the secure connection while using the mail app.
You can choose the country for a secure connection only in the extended version of Kaspersky VPN Secure Connection for Android. If you are using the standard version, disable the secure connection while using the mail app.
To change the country, click the country name under Virtual server and select another one from the list.
