We had an imap account setup in Outlook 2007. Well I copied the pst file over and setup the imap account in Outlook 2013. When I try to open items a few week old I get the following message.
"cannot open this item . This operation is not supported until the entire message is downloaded, download the message and try again".
I right click on the email and mark for download, but clicking process marked items, or send/receive does not work. Banging my head!
