Force outlook to sync TO Exchange

We are in the process of moving to Office 365. This of course includes Exchange as your mail server and it is hosted by Microsoft all in the cloud. Up untill now the transfer of pst to ost has gone smoothly. In this particular case however the user has a large pst (18 GB) on the exchange server it says it is only 11 GB and I suspect that it has stopped syncing actually nothing has synced for about 18 hours now. Is there a way to force Outlook to start the sync again. We are using office 2007 in this case and i assume MS is using the latest version of exchange.

Files over 4GB cause issues.
Get them to break their file into seperate files under this amount.
A good way is to break it into years
Call the current one 'archive.pst' and under advanced call it 'Archive - 2011' (or maybe 2012 by the time you do it)
Now create a new file called 'archive 2010' and call it the same in advanced tab (so it shows on the screen in outlook as that).
Select the current 2011 archive and do FILE, ARCHIVE, set manual and set the date to 1/1/2011
pick to put the things before that date into 2010 file.
repeat this for the 2010 file selecting to move 2009 and before to a new file called that...repeat....repeat....etc

Hi lhuston!

Yes, to “force” the sync try terminating the application and restarting it. If that fails reboot the computer. If that fails it could be a profile corruption, in which case just deleted the OST file, then delted the profile. Reboot and create a new profile. Once the new profile is created, mount the PST file or import it and synchronicity should complete. Let me know how it goes.

Yes, MSFT is using the latest versions of Exchange Enterprise for their cloud services.

If there are more than 5k items in any folder it can cause issues as well. If you find that is the case break them up into subfolders.
