IMAP is not working now that Spectrum.net has eliminated the webmail access. They say it is a Microsoft problem.

Just addressing several points from the last several messages...

Even using IMAP, deleting a message in Outlook would not delete messages off the Spectrum server. I had to manually go onto the Spectrum email web page and perform a mass cleanup 100 emails at a time every week. Spectrum email is an utter joke in this day and age. I have contacted them many times over the years and they are absolutely clueless.

New outlook does have a send/receive function now - it is under the view menu option and is called "sync."

Deleting my email account and re-setting it back up in either new or classic Outlook using POP still does not work for me.

I have uninstalled Outlook from my PC - good riddens I say. Also in the process of phasing out my roadrunner email account and transitioning over to Gmail.

Hi. Had issue today not able to login under new outlook. Contacted spectrum support and while waiting for answer, I tried changing it to POP instead of IMAP and it worked. For some reason IMAP no longer works under new outlook. Hope this helps.

Got a call from my parents last week who are having the same issue with Spectrum/Outlook. They suddenly stopped receiving any email in their Outlook (New) client. I tried many different things to get it working with no success. Tried setting it up on my personal computer as well and again, no success. Attempting to setup the account fails and the troubleshooting button gives the error code mentioned previously: INVALIDCREDENTIALS TEMPORARILYUNAVAILABLE

I tried the spectrum web mail application and was able to login their successfully. I also tried in Thunderbird and it was able to connect and login successfully. In the end I switched my parents over to using Thunderbird for their email rather than the new outlook.

see my updated reply in this tread. It may be a help.

Hello  Joe Farrell1

Welcome to Microsoft Community.

I understand that you are having problems configuring your Spectrum.net account using the IMAP email protocol in Outlook for iOS.

Generally speaking, the IMAP email protocol is universal and does not usually change at will. As of now, we have not collected a large number of user feedback that their Outlook for iPhone has problems with the IMAP email protocol.

Given the situation you described, it is recommended that you perform general troubleshooting in the following ways:

1. Check account configuration: Please carefully check the configuration information of your Spectrum.net account in your phone with the support manual for configuring the IMAP protocol in third-party mailboxes provided by your email provider to see if there are any inconsistencies. If you find any problems, you can try to reconfigure. This step is critical because even a small configuration error may be rejected by your email provider's server.
2. Check other IMAP accounts: Check whether other accounts configured with the IMAP email protocol in your mobile Outlook are running properly. If other accounts work, the problem may be with the configuration or settings of the specific Spectrum.net account; if other accounts have similar problems, it may involve broader issues such as Outlook software or mobile network settings.
3. Try Apple Mail software: Use your Apple Mail software to configure your Spectrum.net account and see if it works. If it can be configured and used normally in Apple Mail, it means that the problem may be in the adaptation of Outlook and Spectrum.net account; if it cannot be configured successfully in Apple Mail, it is likely that there is a problem with the settings of the Spectrum.net account itself or its compatibility with the IMAP protocol.

Through these troubleshooting steps, we hope to find out why IMAP cannot flow emails from Spectrum.net to Outlook on your iPhone and then solve the problem. If you encounter any questions during the operation, please feel free to give us feedback.

Thank you for your patience and understanding.
