MS Outlook stop sending receiving email with KSC activated. Is there some configuration to set?

When I activate my VPN Kaspersky, MS Outlook shows sending receiving error and no message is downloaded. Deactivating KSC the messages are downloaded normally. Is there some configurations to set in KSC or MS Outlook?

@sidnei.cordeiro Welcome.

The problem is probably the fact that your ISP cannot identify his own SMTP and is refusing outgoing traffic. On the other hand - which is normal - incoming POP3 is no problem with a VPN connection.

Thank you Berny. 

You’re right, two POP3 account have não problem. The problem show with MS Exchange accounts.
