So you opened Outlook and got hit with that “Errors have been detected in the file Outlook.OST” message. Now nothing works right. Emails aren’t loading, syncing is stuck, and maybe Outlook won’t even start. It’s one of those errors that shows up at the worst possible time, usually when you actually need to get something done. But don’t stress too much over it. This blog covers what’s going on and how to get things working again.<\/p>\n\n\n\n
