ContributionsMost RecentMost LikesSolutionsRe: Transition did not bring much.... I am having a similar experience. After the transition all emails in my inbox seem transferred to Yahoo inbox, but none of other folders I created in last years were copied. Like personal, travel, finance, etc. folders. Cox, is this known/intentional? And what is the procedure for complete the transfer of ALL emails from Cox to Yahoo? Re: The connection to smtp.cox.net failed !??! I may have made a mistake and changed the Outlook SMTP port to be identical to 465, in both Outlook as well as iPhone smtp.cox.net server port instead of the preferred port 587. Not sure which is required but 587 for iPhone, but 465 for Outlook works now. The connection to smtp.cox.net failed !??! My "transition" from Cox to Yahoo was working yesterday. But today when I try to send email from Windows 10 Outlook as well as myemail.cox.net webmail, I get this: Cannot Send Mail. The connection to the outgoing server "smtp.cox.net" failed ... Additional Outgoing Mail Servers can be configured for Mail accounts in Settings/Mail/Account" Are the Cox outgoing smtp servers down? I am getting emails ok, but this error when trying to send. WHY? Same problem using same settings from iPhone as well as Windows 10. SolvedRe: Cannot Send Mail I resent email. In Outlook/Account Settings/Outgoing Mail is a slider bar for increasing the timeout value for waiting I assume for response from server. I don't see any equivalent setting sending from iPad or iPhone. Re: Cannot Send Mail I sent email to cox.help@cox.net but haven't heard back. Meanwhile testing again, outgoing emails are NOW working again. I have no idea what happened, maybe just speculation that the cox smtp.cox.net server was overloaded and busy first thing this morning. So, my question, is there a setting on how long I wait for smtp.cox.net server before timing out? Maybe in some advanced settings? Cannot Send Mail What happened to the instructions that were supposed to arrive once the transition to Yahoo happened? I can send emails from Windows 10 desktop using the Cox webmail address: https://www.cox.com/content/dam/cox/okta/mail.html However I can't send email using the Mail app on my iPhone or iPad. I get this message: "Cannot Send Mail. The connection to the outgoing server "smtp.cox.net" failed. Additional outgoing Mail Servers can be configured for Mail accounts in Settings > Mail > Accounts>" How can I determine if I am in "transition" or some other problem? Can I choose transition start date? Is it possible to choose or delay the individual Cox/Yahoo transition conversion date? Due to out of country travel plans over next month, it is impossible to deal with all the steps necessary for a successful transition. The easiest would seem to allow a Cox customer to postpone for a month etc. Or consider asking customer to accept or defer in an email when it gets close. It's impossible for me to believe all of the "stories" posted here can be resolved if traveling in Europe or Spain, etc. Do we get toll-free telephone customer/tech support from all over the world to resolve issues? PLEASE help! Re: Help! I already have had a Yahoo account for years. I don't know if it transitioned or not. I changed password on iPhone and was able to send emails, but when I just now tried sending email from iPhone with new changed password it said "Cannot send Mail. The connection to the outgoing server smtp.cox.net failed. ... "NO space left on device" What does that mean? Re: Help! I already have had a Yahoo account for years. Thank you LisaH for helping. I guess I haven't completely gone through transition 100% yet. I can send test email from my iPad to another cox account, but when I try sending test email from iPhone to another cox account, I get this: "Cannot Get Mail" No password provided for "Yahoo" Please go to Mail account Settings and enter a password. Any ideas? Both are set as POP3 server settings. I went to my-account-settings and entered my password and got red error message "Invalid password. Please try again" Help! I already have had a Yahoo account for years. Help! I already have a Yahoo account for years. Now what do I do to complete the transition? Did Yahoo create a new different abc@yahoo.com account and password? Or a abc@cox.net account? I don't see any information for users with TWO yahoo accounts. I can't log in! Does it matter if server settings are both POP or IMAP or mixed? for this transition. Need some detailed instructions. (I've looked and searched but not found anything yet for this situation.
