Zoho Mail in Blackberry - duplicate incoming emails

Zoho Mail in Blackberry - duplicate incoming emails

Hi.

We have an issue after we setup the pop settings in a Blackberry Z10. We are getting all the incoming emails twice and also all the emails to the account cliffwalker@zoho.com.  We want the emails to the account cliff@cliffwalker.co.uk and one incoming email. The settings are all ok. Email: cliff@cliffwalker.co.uk; server: pop.zoho.com: port 995; SSL - yes. Outgoing; server, smtp.zoho.com; port 465, SSL - yes. 

We need help ASAP.  Thanks.

Lorena
