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)

    I don't have the time or inclination to participate in a class action, and I certainly don't want to start dropping 1000s paying attorney's fees. Instead, I'm going to vote with my feet: I am currently a paid subscriber to Yahoo! Business email and I plan to switch to another provider, possibly paid Gmail as their IMAP support seems very good. I know Yahoo! isn't going to care about the loss of one subscriber such as myself but this battle has gone on too long with no end in sight. I have a strong technical background and can assert confidently that this isn't an Outlook problem per se ... I ran a test using Mac Mail and got the same result (spontaneous and repeated resyncing). I have also inspected the Yahoo! server's IMAP responses using openssl and don't see anything obviously wrong (UIDs are stable, etc) so I have no idea why this is happening.

    When the export.imap.mail config stopped working properly a week ago, I changed my servier back to imap.mail.yahoo.com . Everything repopulated in the folder properly. However, I had all folders broken up into 10,000 emails or less well prior to that when this whole issue first started 6+ months ago. The latest Windows cumulative update caused the Outlook profile to request repopulation of all emails, and when I saw that I thought something had gone wrong again on Yahoo's end. This was simply the Windows update which affected the Office and Outlook products.

    Anyway, it's all working again ... for now.
