Hi @Stefan Grönberg
To transfer Outlook settings to a new device, you can save Outlook settings to the cloud. The new Store my Outlook settings in the cloud feature in Outlook Desktop stores your Outlook Microsoft 365 account settings and preferences in the cloud, automatically roaming across all your Outlook for Windows clients.
Please go to the Outlook client >File>Option>General>Store my Outlook settings in the cloud.
Then add an account on your new device.
For more details, you can refer to: Information about Store my Outlook settings in the cloud - Microsoft Support.
Hope this helps!
