Your document library will be connected to Outlook. To get the latest, click Send/Receive.
After you've clicked Connect to Outlook and downloaded the library files, Outlook will keep a connection with that library. If you need to make sure you have the latest files on your computer prior to leaving the office, click the Send/Receive button in Outlook before you go.
Note While you are still in the office and have an Internet connection, the latest files from the library will be automatically downloaded to Outlook in the background — you won’t be notified; it will just happen. How often does this happen? Every hour.
