Unable To Recieve Outlook Email But Can Get Webmail

All of a sudden Outlook stopped receiving emails and on my Android as well, but can send emails and can send/receive on Webmail. This is not a issue with settings because it just suddenly happened.  Here is the error:

Task 'xxxxxxx@comcast.net (2): Folder:Inbox Check for new mail.' reported error (0x800CCC0E) : 'Outlook cannot download folder Inbox from the IMAP email server for account xxxxxxx@comcast.net (2). Error: Cannot connect to the server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).

I tried a reboot, cleared cache then Scanpst then Outlook/Safe Mode then verified the settings.  The Repair Option got the following error:

"We couldn't connect to the incoming (IMAP) Server"

After I completed this post I scanned this forum and found multiple posts for the same issue without a specific resolution.

Please help.

@joep63 - I believe I experienced the same thing (and I believe, though I'm relying on my memory here, that it has happened a couple of times in prior years as well) and as before it has resolved itself after being "unable to connect to server" (with that blacklisted log entry).  Beginning today my IMAP connections from Outlook (classic) and Apple Mail (iphone) are back to full normal operating mode.  I didn't do anything (to cause it to start failing or to cause it to resume working), just waited 5 days and it cleared up on its own.  I suspect Comcast was working on security around IMAP connections and inadvertently broke it.

Now to be fair, Comcast operates this email service at no charge (and amazingly extends that service to prior customers indefinitely!).  Given the situation I can understand why they are migrating it over to Yahoo as it's likely a drain on their resources to maintain it and it's increasingly not a part of their business model.  Another company might have just "cut it off" with perhaps a few days notice - I appreciate that they chose a different path.

Having the same issue. Can send and receive emails to my Xfinity webmail account, however Outlook on my desktop and Bluemail on my phone are not working.  I thought it could have been my firewall, however connecting to a hotspot on my work phone (which bypasses my home network firewall) proved the issue has something to do with Comcast and not a firewall restriction (plus you folks are also experiencing the problem). 

If you log onto your Xfinity webmail, click the gear icon on the top right, then select the "Security" section on the right panel, there is a "Third Party Access Security" setting which must be enabled.  Mine is enabled, so my guess is they did something today which broke this feature.

@user_fc6ef1​ Thanks!

I did check that setting and as suggested, unchecked and checked it. 

I believe it is an Xfinity issue because it happened suddenly.  I did not change anything nor did I attempt to change anything since it was running flawlessly for as long as i can remember!

I'm having the same issues (same effects and error messages), with both Outlook Classic on my Windows 11 PC and on my Samsung Android phone with the Samsung Email app.  I am able to access my Xfinity/Comcast email using Webmail, so the issue is not with my account, it's with accessing the Comcast servers. I have verified that the 3rd party app access is enabled on my Xfinity account. I also removed my Comcast email account from my phone and when I tried to re-add it on the phone, I was able to authenticate the password, but get "Couldn't verify account. imap.comcast.net isn't responding. You can continue the setup process, but you won't be able to send or receive emails until your account has been verified."

I first noticed this problem this morning around 9:30 AM EST.  Everything was working fine last night.

Please help!

@user_mn2chd​ I'm having the exact same issues here.  Last time I was able to receive any email in Outlook was about 9:15am on 12/8.  Oddly enough, I'm still able to SEND emails but can't receive them (except via the webmail interface).  Have NOT migrated to Yahoo mail servers yet...

Never received notification about moving to Yahoo (which I vehemently do NOT want to do) but IMAP is the problem where I am at the moment.  I can send emails so SMTP isn’t failing but can’t receive anything.  I’ve had this happen many times in the past and it obviously clears up on its own since there is nothing that can be done on the user side to fix it.  Web-based mail works (although, in the past, it was also failing) but using Outlook on my iPad or the Apple mail client on my iPhone does not.

Note that I’ve tried disabling my WiFi to force it to go through my cellular carrier but neither work.  Pinging the IMAP server fails so I think DNS resolution may be the problem.

@user_1ef7bd , yes I agree, it eventually clears up on its own, in my case seems like about 5 days.  And I concur that this has happened a few times before over the years, always clearing up on its own after a few (too many) days.  One technical note - ping is often disabled as ping flooding and similar approaches can be used nefariously to impact services.  Instead of "ping" you might try "nslookup imap.comcast.com" which will (only) look up the DNS record(s) for the address.  While my Comcast accounts were not working the nslookup approach successfully resolved the address for me.  My advice is to do nothing and check again after 5 days.

FYI experiencing same issues as above. Cannot receive emails from IMAP server. Am not currently getting any IP Blacklist message this go around. I've changed password on Web version of email site, and deleted accounts in Apple Email Accounts and readded. No luck.
