New Outlook and Spectrum Email issues

Karl Paisley 0

Until two weeks ago, my New Outlook retrieved and sent email without any issues to my Spectrum IMAP account via mail.twc.com. It has stopped working and I can not add this IMAP email. It works in Classic, but I'm expecting full service from MS for my out-of-pocket paid subscription. All of my setup details are correct so what is the fix MS?

Hello,

The issue does not appear to be with your Outlook app. It appears to be on the Charter/Spectrum side.

You are not the only person reporting this over the past few days. I have spoken with users on both Mac and Windows, using different email apps, who are experiencing the same problem.

I have also been checking a third-party independent email delivery monitoring service here:

https://prr.groups.io/email-provider-status?isp=Spectrum+%2F+Charter

This is the screenshot I captured last night:

As of now, the service reports Spectrum/Charter as "healthy," but the charts still show spikes in delivery problems. Nearly 97% of the reported delivery failures were listed as "temporary resource unavailable."

For now, you may need to use Spectrum's webmail until the issue is fully resolved on their side. You can also contact Spectrum support directly to ask for an update on the current mail server issue.

I talked with Spectrum and could easily log into my mail account and receive mail. The problem is with Windows11 New Outlook mail that wants me to log in as a new user and when I enter my password, I receive a " sign-In-Failed " and "Something went wrong while setting up your account. Please try again" I had no issue logging into my email until about 2-3 weeks ago. Here we go again.....IMAP or POP issues again. Personally, I would go back to Windows 10 in a second. How long will I have to wait for an answer.

Being able to sign in to Spectrum Webmail does not prove that the IMAP/POP/SMTP service is working. These are two different ways of accessing the same mailbox. Like using different doors/security systems to access the same house.

When you sign in through Spectrum's website, your browser is authenticating with Spectrum's webmail system. Outlook and other email client apps, however, has to authenticate and communicate with Spectrum's IMAP/POP/SMTP mail servers. One can work while the other is having problems is completely normal.

In your case, the fact that Spectrum Webmail works only confirms that your account and password are valid. It does not rule out a problem with Spectrum's IMAP/POP/SMTP service or the connection between Spectrum and New Outlook. This is also not unique to New Outlook or Windows 11, so going back to Windows 10 will not help.

Same issue on her Mac device, and same issue when she switched to Apple Mail app.

I just chatted with Spectrum. They are saying it's an issue on the Microsoft side and to contact Microsoft support. Of course they did..... :-\

Spectrum acknowledged a problem with Outlook when I spoke with them on 8/22; they even inserted a recording within their support hold message at the time stating that their engineers were working with MS. The issue appeared fixed on 8/25, all my charter.net email back filled in Outlook and worked. On 8/28 in the afternoon (EST), the system went down again. I called Spectrum today, and after 45 minutes of discussion and hold while the CSR spoke with his "team leader", they gave me the same answer that Karen Rice got, it's a MS issue. They seemed to have contracted corporate amnesia regarding their engineers working on it..., claimed to have no record of their recorded message from 8/22.

This failure is occurring in all my imap accounts, Outlook 2021 classic on Win 10, Outlook 2024 classic on Win 11, and the Outlook app for Android. All the email is updating in the Spectrum portal; no surprise there per EmilyS_726. Further, Gmail is functioning normally in the Outlook classic client programs. Given that MS releases frequent app software updates, it's at least plausible that parts of the issue may implicate both Spectrum and MS.

Mine has been doing that for 3 weeks now. Funny part is it works during the week and only fails from Friday night to Sunday night.

I spoke to Spectrum for the third time last week and they reminded me that I had an IMAP admin email address on mail.twc.com. I tried adding the admin email address to my New Outlook app in Win 11 and it did work though there were no email entries to this unused address. I then tried to add my legacy IMAP address through mail.twc.com and to my surprise, it loaded and fully populated the email content and my calendar. I was elated to have found this trial-and-error resolution on my own (kudos to the Spectrum agent for the admin email reminder though he said that "we're working on it").
