I had the same problem some time ago. Every day I used to get a lot of emails with attachments, and saving them one by one was a very time-consuming task. After a lot of searching, I tried
Softaken Email Attachment Extractor, I could not find an easier way than this. You can get all of your email documents out of this tool. It can get files like PST, OST, MBOX, EML, MSG, and more. It does not require Outlook to be installed, and there is no need to open any mail.
The good thing about this is that this tool is compatible with all versions of Windows: Windows 11, 10, 8, 7, etc. Another advantage is that you can decide whether you want only files or any other specific type. Also, all attachments are exported cleanly, without any data loss. You can try it out for free first, and then when you're sure you want to use it, you can do so. If you get stuck in any step or face any problem while using the tool, its support team is available 24/7. You can easily get help through Email, Live Chat Support.
