Today I enabled Outlook cached mode for mailbox and it started Syncing all my email items. But one thing I couldn’t understand is, in what order it is syncing the folders. I got to see few mails urgently and that folder is not yet synced. I quickly searched in internet and came across a simple trick to force sync the folder I required.
It is very simple, just select the folder that you want to Sync and press SHIFT+F9. Outlook will start Syncing your folder immediately.
Hope this helps. 🙂
