Inbox has limited content

Inbox has limited content

Hi, 

I have a remote email account that I am using with Zoho via IMAP. The account Inbox seems to have a limited number of emails compared to the remote account Inbox. I can see all the emails that are there if I select Views - All Messages. If I just click on Inbox then only a few recent emails show.

Any way to get Inbox to show all my emails without going through the additional stage? I do have a number of remote IMAP accounts and they all behave in the same way.

Thanks
