I'm having problems with a GMail account used over IMAP. The problem is that inbox is full and there is no space left. After deleting about 11000 of oldest mails, there were only a few hundred left and they take up more than 70% of mailbox. I'm looking for a nice way to sort mails by size so that the largest may be deleted. I found way explained in this question, but it's related to Thunderbird. So what I'm asking is: Is there and easy way to sort mails by size in Outlook 2007 or 2010?
While I know that one possible solution to this problem is to install Thunderbird, user of the GMail account is someone else and she is a fan of Outlook, so I'd rather find a way to do this without installing Thunderbird.
I also know that I can click on the column which shows size of mails, but this way mails come sorted by dates and sizes. Is there any way to just sort them by sizes without sorting them by dates?
