Why is an IMAP Inbox Only Displaying 10,000 Items When There are Many More Emails on the Server?

I have an IMAP email account that is hosted by AOL Mail, which I download into Outlook 365. The AOL Account has emails going as far back as 2015, and until recently all of those emails were visible (and searchable) through Outlook. About 2 weeks ago, I noticed that I could no longer search for emails going back farther than 6 months ago. Those emails are still on the AOL server; I can see them if I use AOL's webmail interface (which is pretty mediocre). But they are no longer downloading into my IMAP inbox. Indeed, at the bottom of the inbox it now says I have 10,000 items.

                                     [!\[\](https://learn-attachment.microsoft.com/api/attachments/40c12e9d-b5a2-4a30-8bc4-4503de01cbbc?platform=QnA

That's the maximum. If I delete say 100 emails, another 100 emails will download from the AOL server but the downloading will stop when I hit 10,000. (When new emails download from the account, older emails are deleted so I'm just about always at 10,000 items). The full set of emails remains on the AOL server.
In my IMAP Account Settings for this email account, I have the "Keep Mail offline" setting pushed all the way to the right at "All".
[!\\ I can't find any setting in Outlook that limits the number of emails. Nor does there appear to be any setting in the AOL account that limits 3rd party IMAP mailboxes to only 10,000 items (at least not one that I can find). New emails are downloading and syncing with the AOL server, so my connection settings appear to be correct.
Is there some kind of Registry setting that is limiting the number of items that will load into this email inbox? I used to have access to all of the emails that were on the AOL server. Is there any way to get that back? One last note. I deleted the AOL account from Inbox, rebooted and then reinstalled the AOL account. It still only downloaded 10,000 items in the IMAP inbox. Also I'm using the most recent version of Outlook 365.
Thanks for any help anyone can provide.](https://learn-attachment.microsoft.com/api/attachments/e4efa42d-54c3-4fa7-b54a-ae7d93efb421?platform=QnA)](https://learn-attachment.microsoft.com/api/attachments/40c12e9d-b5a2-4a30-8bc4-4503de01cbbc?platform=QnA)

    Same issue started a few days ago with Outlook 2019 and using yahoo. My obs file got corrupted and I did the repair and after not seeing older mail past just under 10k records, I then did the recreate that also rebuild the whole osb file but again stopping populating the inbox at 10K. Very annoying.

    Exactly the same story here for the past few months or more. They haven't fixed anything.

    Has anybody found a solution to this? Having been elated to find that switching to export.imap.mail.yahoo.com enabled me to see all my emails, my joy was short lived as I too have finished up in a never ending cycle of downloading.

    The other day one of my folders (small, under 100) could not do a search. Checked indexing status and I had over 20K items remaining to be indexed? Wondered why it was reindexing -- thought maybe the main index had just rebuilt. BUT the inbox was complete.

    I just checked now and had about 12K remaining to be reindexed.. and then the number went up. Inbox looked complete.

    SO I checked the 5 folders that I had moved <10: messages (each) to. Mostly filled on one PC; no the other 4 were suspiciously at exactly 2000; the other one was growing. Checked later and the second one was growing. So the claim that folders under 10K would be exempt and help is prob'ly wrong, Not definite because at this point, unless/until I get the main inbox under 10K, they can claim that that is what triggered the wipe-out/rebuild.is due to inbox being too kigh.
