SOLVED: Outlook 2007 IMAP “The folder … cannot be selected”
Here’s an obscure one. I was escalated a call today (my job involves, amongst other things, third line support for email issues) where a user was unable to delete or open some items of email within Outlook 2007. An error message pops up saying, “The folder … cannot be selected. This may be because of a limitation of your IMAP server or the folder may have been deleted or moved.”
It turns out the error message is a bit of a red herring. By a process of elimination (starting Outlook in safe mode and selectively disabling add-ins) I found the culprit to be AVG Free. Whether the blame lies with AVG or Outlook 2007 is a moot point. Microsoft has taken a long time to implement IMAP correctly, so I suspect the latter. Whichever the case, no one in a corporate environment should be using a product not licensed commercially, so I sent my user off to buy Kaspersky Anti-Virus.
