I have Outlook 2011 installed on a MacBook Air setup with an Exchange email account. Everything has worked fine with no issues at all for the last year or so until now... When I open Outlook I am unable to move messages from one folder to another (within the exchange, not locally) and I am unable to rename new or existing folders. When I try and move messages they just stay in the existing folder and if I try and rename a folder it flashes with editable text for a second or so and then just goes back as if I clicked off. Sometimes in the bottom right corner it keeps switching from saying "checking folders" to "folders up to date". It's as if the server is constantly refreshing itself and stopping me from doing anything. If I set Outlook to work offline everything works perfectly, I can move things around and rename with no issues. It's only when working online that this happens. Any ideas?
