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)

    For some of us on AOL (but not all), this "solution" loses access to the Spam or Bulk Mail folders in outlook, meaning we have to log into AOL or webmail to check them.

    I have implemented the 'export' fix some weeks ago and it works for me. However, I do not want to be at the mercy of an undocumented and unsupported workaround or a 'hack' that can disappear any day. That is why I still want to try and pursue an official resolution provided by the company management.

    I'm repeating my post here, so it's more clear:

    My experience and "fix" is for the Mozilla Thunderbird email program:

    At some point in the last few weeks, Thunderbird showed only 10,000 emails on the AOL server,
    whereas logging into www.aol.com and accessing the emails via browser
    showed the full count of 33,000+ emails.

    I found a lengthy thread discussing this at the following:

    https://answers.microsoft.com/en-us/outlook\_com/forum/all/why-is-an-imap-inbox-only-displaying-10000-items/6d15de5f-9047-4b41-9b58-1d8345bbd002

    The bottom line to "repair" this (at least temporarily) is to
    change the IMAP server setting from:

    imap.aol.com

    to:

    export.imap.aol.com

    And, for Yahoo...

    export.imap.mail.yahoo.com

    I did this on my Thunderbird (Version 102), and now all is correct.

    It did take quite some time to re-index all the "new" emails.

    Good luck.

    For those on this forum who remember that about a month ago or so I have sent a letter to Yahoo Inc CEO and CTO detailing the 10000 emails limit problem and asking for a fair and effective resolotion:

    The letter has returned because the envelope got damaged and the address could not be found. I was away for the last three weeks and only learned about it today. So I will be sending the same letter again.
