Hi,
Self had been receiving the following the error on configuraiton of outlook 2013 for Zoho mail
"Receiving reported error (0*800CCC90). Your incoming (pop3) email server has reported an internal error".
This happens either I try it using the normal login method or try it using the 2 factor authentication with applicaiton specific password.
Request you resolve the same asap. Zohowebmail seems to work properly.
Cheers
BVP
