Using Microsoft Outlook for Mac version 16.54 Microsoft 365 and receiving bounce back when "New Outlook" toggled on but no bounce when toggled off.Using Microsoft Outlook for Mac version 16.54 Microsoft 365 and receiving bounce back when "New Outlook" toggled on but no bounce when toggled off. A Gmail account does not have the same issue. The bounce error is: SmtpSubmissionPermanent5XXException: Smtp submission failed. Server 'smtp.cox.net' Port '465'. --> Unexpected SMTP server response. Expected: 250, actual: 503, whole response: 503 not available Failure code: 5513 Updated the password per Cox' support site, but didn't resolve. When sending with the "New Outlook" toggled on, the above bounce happens but toggling off "New Outlook", email sends fine. No problem receiving emails either way. Checked for Office update and it says Office is up to date. Any suggestions?
- This frustrating issue still hasn't been resolved with Cox in spite of a month of back and forth with Cox techs at all levels, including supposedly having "the Cox Engineers" check that nothing is wrong at their end that is blocking our ability to connect. We get the same error messages when trying to add cox account in Outlook 365 or on my Pixel 3 phone (Verizon) or even using Microsoft's email program that comes with Windows. It says "something went wrong...check your email account or password". We upgraded to Office 365 in early 2020 and all was fine until (long story) on 10/10/21 a Cox agent through Chat eliminated our email account and set up a new one after we asked if we could change our user name without losing our email. The email was lost! It took about a day or so, but Cox was able to delete tha2nd email account and restore our original one. The old email account began working in Webmail, but still cannot be accessed through any other email program. We assumed issue must be with Outlook (which is what we first tried). Geek Squad remoted in, couldn't fix, Microsoft tech support levels 1 & 2 tried, then we went to Cox support. Cox Complete Care Techs couldn't fix it or figure out why not workings, so on several occasions they upgraded the request to their 2nd level support (CAG). Finally CAG gave up trying too, told us there was definitely something blocking us from connecting and since the problem was the same not only with Outlook but also Microsofts other email program and the phone's program, it had to be on the Cox side. They twice ended up escating the ticket to the Cox engineering group to see what on the Cox side was wrong in our account. Both times (without telling anyone), "the Engineer"closed the ticket without solving the problem. Our email is visible and working in Webmail (only), which is really inadequate! We've been full service Cox customers for decades...really unhappy now. What's been tried: All cox.net settings for IMAP & POP confirmed and correct -- don't work Cox user name and password verified and working for account and for Webmail Other variations in settings and ports by Cox techs didn't help Office 365/Outlook uninstalled and reinstalled Outlook Profile changed - no difference Password changed - no difference Best Buy Geek Squad, Microsoft Tech Support and tech support agents at Cox have said issue must be on the Cox side somewhere. Needs advanced technical suppot...which we don't seem to getting. A customer service tech originally caused the problem (didn't seem to know that by changing the user name for the email account you are setting up a new email account and the old email won't be linked...it will be lost. It isn't right that Cox seems to be throwing up its hands and saying we don't know what is the problem with email not working now, but nothing more we can do. Help!
- Hi all, Like all (?) Outlook users, I lost the ability to receive mail a week ago (I could still send). I use Windows 10 Pro, version 1903 (OS build 18362.746). I am using Outlook Version 1911 (build 12228.20332). I fixed my connection issue by disabling the use of TLS 1.0 by Windows 10.I suspect the "maintenance" was to require TLS 1.2 connections. Our Outlook clients are trying to connect using TLS 1.0 and get rejected. Here's how I did it. The first step may not be required -- I think it was the second step that was definitive. NOTE: These directions are essentially the same as those here:https://windowsreport.com/how-to-disable-tls-1-0/ 1. Disable TLS 1.0 in Internet Settings Press Windows Key + S [This will bring up Search] Type "internet options" into search bar The Internet Properties window pops up Select the "Advanced" tab Scroll down to the bottom, the "Security" section. Uncheck "Use TLS 1.0" Note: I also unchecked TLS 1.1, and I checked Use TLS 1.3 (experimental). You may not need to do that. 2. Edit the Registry to Disable TLS 1.0 Press Windows Key + R [this brings up the "Run" window] type "regedit" in Run to run the registry editor Then, in the left-hand tree view, open up this key path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols I couldn't see TLS 1.0 and Client subkeys went I arrived at the end of the above key path, so I had to create them. To create them: right-click on Protocols and select New > Key then enter "TLS 1.0" as the key title Next, right click on the TLS 1.0 key you just created, and select New > Key again. Enter "Client" as the title. Then, select the Client key, and in in the empty-space to the right of it, right-click and select New > DWORD (32-bit) Value Enter "Enabled" as the new DWORD's title The default value for this new Enabled DWORD is 0 (zero), which disables TLS 1.0. Finally, restart Windows (reboot). My Outlook IMAP Settings for Cox The above procedure should have restored your prior configuration to a working state. If it's not, here are is my working Outlook configuration. Recall that I am using Windows 10, with OutlookVersion 1911 (build 12228.20332) as part of Office 365. Note that I use IMAP and not POP. It Outlook, select the File menu In the Account Information screen, press the "Account Settings" button, then select "Server Settings" The IMAP Account Settings -- Incoming mail -- window appears: Now press the "Outgoing mail" link in this window. Now the IMAP settings for outgoing mail appears: Good Luck & Merry Christmas!
- I spent time with the cox.net support representative and they couldn't solve this issue. I also spent time talking to Microsoft today (to solve an unrelated issue) and they helped me out with this one as well, but to no avail. No matter what I did, Outlook 365 will not connect to cox.net. Procedures tried: recommended cox.net settings for both IMAP and POP email. both don't work Variations on all settings (SPA, ports, etc.),made no difference using a brand-new Outlook profile. No change using other email programs. In my case, I used Thunderbird to access the IMAP server with no problems, sending or receiving email. verified password and connection to cox webmail. Check! I'm honestly not sure at this point how to solve my problem. Am I just stuck with another email program? Lame.
