Email to Text is not working

Hi there @hgmc98 we'll be happy to help you out with email-to-texts messages. 

We'd like a bit of context, to better understand the scope of your issue based on your initial message. We do have some questions we would like to ask, so we can look into more troubleshooting options.

• Are the email-to-texts unable to be sent, or received? Try resetting the network settings of the sending or receiving device in question. This will refresh and improve the device's connection to our network, which will help it get or send texts messages. 
• Please be aware that resetting network settings will erase all saved Wi-Fi, Bluetooth and connection settings.    

• Are you getting any error codes when sending email-to-texts? If so, then the recieving address may be incorrect. We recommend you double check the formatting of email-to-text recipients. 

• Is this occuring only with email-to-texts, or text messages to AT&T numbers in general? Knowing everything that's effected will allow us to perform more accurate troubleshooting. 

We look forward to hearing back from you with the results.

Same issue, AT&T is randomly rejecting identical email to text messages.  Using Office365 as our email relay.  These messages are all what O365 received in response from AT&T.

worked fine at 4:41 am.

2 hours later at 6:53am, same email to text alert is rejected by AT&T.

Status: Office 365 received the message that you specified, but couldn't deliver it to the recipient (‎xxxxxxxxx@txt.att.net‎) due to the following error:<br /><br /><b>Error:</b> ‎550 5.1.1 <xxxxxxxxxx@txt.att.net> recipient address rejected‎<br /><br />A non-delivery report (NDR) message was sent to (ORIGINALSENDER)‎. The NDR might provide more details about why the email message wasn't delivered and how to fix the issue.

Another 1.5 hours later, working again.

Status: Office 365 successfully sent the message to the following external address:<br/><br/><b>External address:</b> ‎xxxxxxxxxx@txt.att.net‎

We are experiencing this same issue.  We have systems that send codes via SMS using the @txt.att.net email address. The messages are not being received.

We are experiencing similar issues from a third party system. We were using mms.att.net which worked for several years no issue then a couple months ago some phones stopped receiving the messages or became sporadic. Then a couple weeks ago we switched it to send to the txt.att.net and started working for everyone. Now as of June16th we are no longer receiving our text alerts.

Opened a ticket with AT&T chat.  My email to text has been working for a few days now.  Hope you are all having better connectivity too.

[ATT] : I have checked that for you , since email upgrading activity is going on, that is the reason you are facing issues with. It was escalated already , they are working on it for you.

[Me] : When can I expect that the email upgrading will be completed?

[ATT] : Once done you will be notified. Also I have placed my request too for you from my end and this is the ticket request I--xxxxxxxx .

[ATT] : It will be completing by today as they are completed the activity , still they are working with the server sync issues.

Thanks for the update - I hope it works well for you.
