Not sure what happened but suddently my inbox has dropped from several thousand to a couple dozen (new emails). For some time I have been unable to access 4 of the accounts that I pole properly... I receive the following error message "The message from YXXXX <XXX@XXX.com> concerning “XXXXXXX” has not been downloaded from the server. You need to take this account online in order to download it." I can restart the mail application and then open the emails from one of the effected accounts with no problem however if I switch between email accounts I then encounter the problem again. About a week ago I stopped being able to access one of my accounts at all and began to permanantly encounter that message, however new emails will pop up- i just cant open them. It is this account that the emails have now vanished from. This work email address was moved onto an exchange server about a month ago. I have a PC (in office) and Blackberry which also pole to this account. Can anyone help?
