Helo! (not sure if anyone will though LOL)

I am surprised that your outbox spanned upto 125 pages.

I'm surprised it's only 125

@OP: my method is Search for "e", by user Royse777. That shows almost all posts in my Inbox. I check the date of the post I'm looking for, and go to the same date in my Outbox (that takes a few clicks). I usually find the post there.
If you're looking for a user who never sent you a post, you're out of luck

Another idea: download all pages. Use browser.altClickSave (note that I haven't tested this) and you run through your 125 pages in 3 minutes. Do a local text search, and keep the data for next time.

so I find it interesting that I am 28000/43000 = 65% of my posts. Damn it is a lot

Let's do the math. Your regular posts are 43,700 and your inbox is 28,000 = 71,700 posts

You have been active for about 11 years
71,700 : 11 years = 6,518 post per year
6,518 : 365 days = 17.8 posts per day,

That's crazy, you are really a high quality spamer, LOL   
In fact, your posts are more than Robot ChartBuddy

Do you still have 10 fingers after writing that much? 

Yeah but my time is numbered chart buddy will pass me by next year.

But if the messages have a subject and not just "no subject", it will help with this search.
If we all have appropriate attitudes when using MPs, everything will be much easier when it comes to finding a conversation.
Small gestures, big results.

Are you thinking of retiring from the forum? Or are you afraid of the competition?

For the time being there are two things you can do to help yourself in the future as it's unlikely that we will see a change to the forum's PM system.

1. Regularly delete PMs that you don't need to maintain a shorter history.
2. Figure out the earliest and latest dates the PM was sent, and with a CTRL + F + 'keyword' or 'username' go through the pages one by one, taking into consideration suggestion #1.
