We recently moved our DNS from GoDaddy to our own internal server, which implies all the necessary DNS records have also changed. We had an IT guy backup all Outlook files before we changed DNS hosts but he missed 3 mailboxes. We need to somehow download these files from webmail on a browser or through any other method because we can't waste time on reverting DNS to point to GoDaddy's servers, backup the files, and then changing DNS back to our own server. This would be a last resort scenario.
We obviously can't sync the account with any email client due to the DNS changes. Any ideas?
