We changed to a new mail server in work and now my mail is all messed up on my iPhone. Tells me one minute that I have 42000 new mails and then a minute later I have -3 mails (yes, negative 3!!). What is going on? Also, each time I open the mail app I do not see any mails but instead the prompt to "Load more messages". This never happened on the last server. Is the issues on my side or on theirs?
