Well; you can try all the MS Fixes that Microsoft suggests; but you may still not get around the issue.

The easy way out is to open your email from its web access. Since the Outlook crashes as the mail downloads; its evident that one of the emails causes this issue. So your task should be to identify which of them triggers the error.

Move the emails from Inbox to another folder (say drafts or any custom folder) from the Web Access. From this folder; move one email at a time to the inbox followed by trying to Send/Receive from your outlook. This way you can identify which email gives you the error on outlook.

It may not be the best way to resolve the issue; but a lot better than spending hours searching and applying Microsoft fixes and get everything messed up
