Exporting/archiving UTmail+ account content locally (in addition to keeping it on the server) allows messages, contacts, and calendar items to be accessed when the computer is not connected to the Internet. Please note that when new messages, contacts or calendar items are added to the active account, the archive does not automatically update.
You can also export/archive content to local storage and delete that content from the server to reduce the total storage used that counts towards your storage quota. You maintain a record of any saved content in the archive.
Finally, you can import the archived content into Outlook and move it to a new account if necessary.
These instructions are for the Legacy Outlook only. Please ensure you are not using New Outlook by checking the toggle switch in the top right corner of Outlook. If it says "New Outlook", toggle it back to the old version.
