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?
