I recently set up to receive messages from my work account via pop in zoho mail. Everything is fine. Now, I also set up on my iphone to access to zoho mail account. However, only the @zoho.com account is shown but not the work account. Is there a way to display my work account when I access to my zoho account on iphone?

 

Another question is, after I set up the work account in my zoho account on the computer, it has fetched more than 10,000 mails which are shown as "Unread". I need to change all of them to "Unread". But so far I can only select 200 messages at once and this would take me forever to change all of the more than 10,000 messages to "Read". Is there a way to select every and all messages at once?

 

I appreciate your answers.
