The+data+file+was+not+closed+properly

Outlook error message upon opening:

//The data file  was not closed properly//

If Outlook doesn't shut down properly then it has to scan the database to ensure email integrity upon opening again. There is no way around this message once you see it so you have to wait for Outlook to finish scanning the OST file. The only thing you can to about this issue is prevent Outlook from closing imporperly in the future.

Remove Addins
The most common reason that Outlook doesn't close properly is an Addin that is still running when Outlook is shutting down.
