Outlook 2011 can’t rename IMAP folder: "RENAME failed: invalid argument"

Hi all,

Am trying to rename an IMAP folder in Outlook 2011 (Mac) and it is failing with error "RENAME failed: invalid argument" (error code 1025) and/or "Connection to the server failed was dropped" (with error code -3253). The additional info suggests this is potentially because a folder with that name exists - it doesn't (unless Outlook is making multiple attempts?).

Same operation works perfectly fine in Outlook 2007/2010 on Win7.

NB. The input box reverts to non-editable about 1 second after selecting "Rename"... very strange behaviour?

Any ideas? Thanks!

Best regards,



Chris
