If you’re trying to move your Yahoo emails to your Office 365 account and want to make sure all attachments come along too, SysInfo Yahoo Email Backup Tool offers a simple way to do it. Instead of manually forwarding emails or dealing with complicated settings, the tool lets you log in with your Yahoo credentials, choose which folders you want to transfer (like Inbox, Sent, etc.), and then select Office 365 as the destination platform.
During the process, you can enable the option to include all attachments, so you don’t lose any files that were originally sent or received in your Yahoo account. The software keeps the folder structure intact, which means everything will show up in Office 365 just as it was in Yahoo Mail. This is especially helpful if you have a lot of organized folders and don’t want to sort through them again. It also supports applying filters, so if you only want to move emails from a certain date range or exclude duplicates, you can do that too.
