So, I have to use Outlook at my work. One of the most annoying things is the error

Outlook is using an old copy of your Outlook data file (.ost). Exit Outlook, delete the file, and restart Outlook. A new file will be automatically created the next time you initiate a send/receive

I don't know why this happens, but this is the 5th time in the past 6 months that it's happened. I know the fix is "delete it and rebuild it". I have a fairly large inbox already though and I'd much rather not having to spend 30 minutes or more downloading email each time this happens. Is there anyway I can prevent this error from occurring? Why does it happen in the first place?

I would contact your IT Staff for assistance. – Ramhound Mar 5 '13 at 16:47
@Ramhound have. They just say to redownload it each time. No one in the (programming) company knows why this happens and everyone just deals with it – Earlz Mar 5 '13 at 18:14
How many emails do you have in your account on the server. Are we talking about hundreds, thousands, tens of thousands? This honestly sounds like a server side problem causing a client side problem. – Ramhound Mar 5 '13 at 18:30
