E-mail forwarding form ZOHO account to ZOHO account

A partner of mine has enabled auto-forwarding of his e-mails from his ZOHO account to my ZOHO account. I have verified the e-mail and while we can see that e-mails have indeed been forwarded from his e-mail to mine using a laptop on his work, I cannot see these forwarded e-mails (either as spam or not) on my PC and my computer at work. Please help me this is a professional matter to us.
