As of 11:13 AM this morning, I'm unable to receive mail into my default Inbox. I'm also unable to move messages out of the Inbox folder and into a .pst folder (the full text of the error message is "Cannot move items. The item cannot be moved. It was either already moved or deleted, or access was denied." I'm running Outlook 2010 (32 bit) on Windows 7 (64 bit). I'm able to receive mail into a subfolder under the inbox (it's moved there by an Exchange-side rule) and I'm able to send mail through this Exchange profile. And I'm able to move items in this subfolder to psts. I've tried running the repair tool (twice) and rebooting. There seems to be a problem with the Inbox itself. I should add that I can access and manipulate this mailbox through OWA, it's just client-side that I'm having a problem. How can I fix this?
