It is not a good ideal to store so many messages on Windows Mail. You can lose them if something happens to corrupt Windows Mail. Which is east to do.
Plus, it can slow Windows Mail down.
I would recommend that you create a new sub-folder under Local Folders
(Right click and click New Folder
), and put the messages that you want to store in it. You can then Export
that folder (See NOTE
under step 7
) for storage or as a backup. Delete the contents of that folder in Windows Mail to save space. When you want the messages back, just Import
them from that exported folder in storage or backup.
