I installed a program called MailStore Home program on my Windows computer. With this program you can connect it to all your email accounts, and it will download everything, index it and compress it.
In my case I have around 100 000 emails spread on 3 email accounts.
When I have to find an old email I know I have, I used to spend a long time searching in Thunderbird, Outlook and on Gmail. It could take me an hour sometimes. But, now, it only takes a couple of seconds.
All my emails are stored in about 5GB, so I can carry everything around on a USB stick. Quite handy!
Also, MailStore Home can works as a offline email backup storage. Quite handy if you by mistake delete an email!

Managing tens of thousands of emails across multiple clients like Outlook and Gmail can definitely turn searching into a major headache. Having a dedicated tool to index everything and compress that entire volume down to just 5GB makes a lot of sense, especially for keeping it portable on a USB drive. The added peace of mind from maintaining an offline backup in case an important message gets accidentally deleted is a huge plus as well. Thanks for sharing this helpful breakdown!
Having a centralized, searchable archive for multiple accounts is a huge time-saver, especially when dealing with tens of thousands of older messages across different providers. The ability to compress everything down to a portable USB drive while keeping it fully indexed for quick offline access makes managing message archives much less stressful.
