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

This is mostly confirmed (if not acknowledged), although I think someone saw it mentioned on AOL of yahoo offically: use export.imap.aol.com instead of imap.aol.com and you get them all back. I suspect the batching of updates depends on the power of your PC and/or internet connection. For me, old slow PC had a lot of pauses, newer one moved steadily and finished much faster.

Cost, not sure if it's acknowledged, is that your spam folder by whatever name, spam or bulk mail, is NOT supported in the mail client (exist but empty). For me that's an annoyance but not serious. I like that I can search with the index all those tens of thousands of messages (and in the newer PC, the index built as fast as it came in; in the old one I had maybe 20,000 to go when the mail was all in). If the cost is logging into webmail to check for misclassified spam, I'll live with it. (And moving it in outlook doesn't teach AOL's algorithms.)

I only check the spam folder every few days or less, so logging into webmail is ok. I also flag as spam by logging in (used to do AOL, now I see it can be marked in webmail and it's a little easier). I do that because it learns that way, and it somewhat works (4 of 5 recent McAfee expired scam emails were properly moved; I only had to mark one).

BTW, even if the email wasn't obvious, I would know it's a SCAM because I get it free with my paid AOL subscription. If it was being dropped, I 'd get an AOL email telling me my benefits changed.

I use Mozilla Thunderbird for multiple email addresses on my PC's. The same thing happened first with my two AOL accounts. One AOL and the other an older Netscape that has been acquired by AOL. Then on all my Yahoo accounts. It did not happen to all accounts at once. First AOL, then Netscape, then Yahoo, all probably spaced by a week or so. So this is not Outlook or Thunderbird. And yes, both my AOL and Yahoo accounts still have all the emails dating back to 2010 or older, some 50,000+. Yet my Thunderbird page limits total emails to 10,000. I too deleted one AOL account and reloaded on Thunderbird to no avail. Then I downloaded Mailbird and the same thing happened.

I never marked something SPAM or not SPAM in outlook. If I found something like that I would log onto AOL and mark it SPAM, or select "this is not SPAM", as I was hoping it would help train their engine to mark similar emails. It does seem to work as the number of "your McAfee is expiring" has dropped and they show up in the SPAM folder (when I log into AOL or Webmail).

Thanks for staying with this Norm, BDSolomon, and everyone else who has identified the second issue with Spam. Have we stated the additional unwanted behavior which is happening? You can't look for any good mail in the Spam folder , but ALSO you can no longer Mark anything as Spam. Since there is no mapping for a spam folder to sync, everything I've tried to Mark or Block just goes back into the Inbox and comes right back as new. You can only Delete to get rid of it - each message, each day.

So without proper mapping and sync with IMAP for Spam, we can no longer spam-train from local clients at all. I work with two main email accounts from yahoo servers and this is really getting unmanageable. (We have to now sign on to the web to take care of all unwanted sender issues)

This change is separate from the 10,000 limit problem, as I did update to the "export.." server for my AOL account, but did not change the setting for my Yahoo email. The non-sync for Spam has started happening for both. no words...

anne-0, I mentioned that I wanted to contact AOL but didn't explain why I had delayed doing so (guess I figured including ranting in my Post wouldn't be helpful, as you mentioned).

To clarify, it was that I simply didn't have the energy to endure the pathetic interaction I anticipated in dealing with the Tech Support reps (who should be re-named the "Technically Clueless Non-Supportive reps").

This would have involved trying to convince them that there was a new IMAP server, and getting them to admit there had been a problem and an (attempt) at a resolution, etc., while they asked what kind of machine I'm using and told me it was a Microsoft problem, even though I'd be politely explaining that this happened with all platforms, all mail apps, and my specific situation was irrelevant.

But I'll go ahead and attempt to contact them, even though it will no doubt be useless. Who knows, the last moron told me that they get a "Bulletin" on major issues if enough people complain, so maybe they'll have something helpful to offer.
