Note that the error message I put in the title of this question is abbreviated. The actual error message is below.
I have an Exchange account and using Outlook 2010 as the client. I run in Cached Exchange Mode and have an .OST file locally.
Recently I uninstalled and reinstalled office. I set up a new mail profile when prompted by Outlook 2010 upon first execution of the program. In my initial attempt, I pointed the data file at my existing OST file. In my second attempt, I had Outlook create a fresh empty file.
In both cases I'm getting the error 'Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost).', also shown in this screenshot –> http://drop.io/4rc9v9o/asset/outlook-error-png.
I don't know how to connect with the current profile – that's what I thought I did when I created a new .OST file?
I've had this problem for several days so my OST file is now out of date. Once I get things running I obviously want my active mailbox to update the OST, not the other way around.

Turns out it was an Exchange-side problem. Support told me that for some reason, MAPI was disabled on my account.
