Me too... I think there is a problem with the ntlmssp.Negotiator{} (from: https://github.com/Azure/go-ntlmssp).

Sorry for late reply.

if you are using an on-premises Exchange server (or even if you manage your servers at the cloud), you need to pass the username as AD_DOMAINNAME\\username instead, for examle MYCOMANY\\mhewedy.

I will close this as resolved. feel free to reopen if you face the suggested solution didn't fix your issue.
