We have to migrate emails from
user@newDomain.com. Both oldDomain and newDomain are actually hosted via outlook.com (Live Domains) so it's essentially on the outlook.com infrastructure.
How can I migrate older emails for each user from the older account into the newer account?
Setting up POP3 access throws a popup saying:
looks like you're trying to download from another Outlook account, try linking ...
But we don't want to link, we want all emails from old => new account.
How can we do this?
