Mac Mail sync issue with exhaange
I have an Macbook Air Snow Leopard 10.6.8, using Mail 4.5. I recently came back from abroad and did a bit of filing of work e-mails while on the plane, this was done with Mac Mail being offline. I am now back in the office with my Macbook, connected to the network, back online, but the changes I made while I was offline does not "appear on"/"sync to" exchange 2010, I really don't want to re-do all the filing again, so help would really be appreciated!!. I add that I can send and recieve mails now that I am online, but the changes made before, when I was offline don't seems to implement on the exchange.
Also is there a way to force my Macbook Air to push these changes to exchange?
Thanks
MacBook Air, Mac OS X (10.6.8)
