On April 3 we upgraded from SM 3.3 to 4.0 and moved our services from an external server (multiple domains) to an in-house server in order to better control SPAM and the overall environment.
The manager of the external server was diligent in updating his DNS records as we transferred to our internal server but we had an internal DNS issue and only recently discovered that mail between some domains was still being directed to the old server and the old server was accepting the mail as the old accounts still existed. Mail from external senders was routed appropriately but mail from internal sources was not. As a result we have users with dual mailboxes with messages in each. Of these users most of them use an Outlook client so getting the new accounts updated with emails from the old account was easy.
However, we've run into a handful of users that strictly use webmail and have a large volume of messages on the old account that we need to get to the new account.
Is anyone aware of a utility or process whereby we can recover/retrieve the messages from the old account while preserving the messages in the new account? I searched the forum and kbase for "export email" but didn't find anything suitable to our situation.
Thanks!
