Thank you for the explanation of webmail versus email. I guess it is offered through Kolab Groupware... I will find elsewhere to ask this same question about Kolab.
As for the first question though, I was not referring to a small screen.... this is a full size desk top computer screen of at least 32 inches or more and even when I try what you suggested, which I did several times both before and after your response, it will not display all the folders. Just inbox, drafts, sent, spam, trash, and tasks.... none of the folders I created to sort documents. So again, can anyone tell me how to get my folders to show up so that I can sort my documents? Because I have tried everything I can think of and I have used lots of different mailboxes, but I have never come across this issue.
