I am absolutely stymied here.
I use Outlook 2016 (all updates current) on Windows 10 64 (all updates current) with my AOL account.
Today, between 10:12AM and 11:31AM, it stopped sending and receiving messages.
Outlook shows "connected", but I get a "Send/Receive" error:
This happens whether or not I am connected to my 'home' ISP or tethered to my phone's T-Mobile account.I am able to send and receive messages on my iPad, using its built in standard Mail app. On both WiFi and on its AT&T cellular service.
I am able to SEND messages via my Android phone's built-in Mail app, but I am NOT able to update my Android Inbox ,using either WiFi or T-Mobile. I don't receive an error message, it just eventually times out.
I just set up Thunderbird on my PC using same ports and authentication as Outlook, and it seems to send and receive just fine.
My Outlook sends and receives a non-AOL account just fine.
Checking mail on AOL.com appears to be A-OK. Using Outlook for WebAccess doesn't seem to do anything (no Inboxes, etc., update, and the test message shows in Sent but never did send. Then again, I don't know that I have ever been asked to provide my AOL password to OWA).
My AOL account on Outlook (on Windows PC) last received a message at 10:12 this morning. The next message in my iPad Inbox is at 11:31; it has not yet appeared in my PC Outlook.
I made no known changes to my Outlook configuration.
I attempted a System Restore, which failed - telling me my AntiVirus was interfering. I use Windows Defender, turned it off, and it still failed. (I have successfully used System Restore on this PC, with Defender running, in the past).
I am at my wits' end - it's clearly not an ISP issue (since it doesn't matter what network my PC is connected to). I thought perhaps it was a port issue on AOL's side - but how does that explain the iPad is working fine?
So I am in a pickle. I don't know what to try, or even who to reach out to - AOL? But even then, what is the issue? I know if I reach out to MSFT it will be weeks of back-and-forth was I re-explain everything in this post.
Thoughts? Help?
(And no, "Stop using AOL" is neither an option nor is it helpful.)
