I'm looking for the most automatic way to back up an outlook.com account meaning to download all e-mails, calendar events, contacts, tasks and everything else in any format, so that I would be able to restore all this data in another empty outlook.com account.
Generally speaking, the main goal is to move/copy all the data from one account to another account.
Outlook (classic) won't work in my case because of some issues with the account I'm unable to add it to Outlook (classic). That is basically, the reason, I'd like to copy all the data to another account and start using that. The account itself is not broken, Outlook (new) works with it perfectly fine, but I need to consolidate all my accounts under Outlook (classic).
For a while I was looking for a tool to back up and restore but didn't find one yet. I tried a few but they didn't work.
