SAML 2.0 authentication failed

Let me repeat this again: jumping back and forth between browsers is not the answer because that error is logged in the temp internet files as the controlling cookie, until cache is cleaned.  See answer of May 9th of this topic. Therein lies the problems and the answers. 

Browers have specific preferences that a user can program and that is a far as it goes - its technically not a Profile. Temp internet files are little bits of info gather from the various sites visited - i know i have used temp internet files to retreive data - and are a stored cache on your computer until deleted. Profiles are geared specificly for email and 3rd party email programs.

In reference to 'att docs read' Sorry, but i havent read any ATT docs that is trail and error experience with imap vs pop. Speaking directly to programming 3rd party email apps on laptop: After i created a new att.net email came in like a champ - sbcglobal didnot. Both accounts were pop. The sbcglobal acct start working after I got an OAuth.

I have dealt with this inability of not receiving sbcglobal email for almost the better part of a year nothing to this extreme of being denied access to my email via online logging. I had a secure OAuth on sbcglobal for a couple of months then removed it, access via 3rd party email was denied but online access was granted, then online access was denied. ATT  ***** when they shifted all the real MaBell accounts into yahoo with its aol viral programming. 

[Per Guidelines: Keep it Relevant and Appropriate]

I wasnt finished when my android so rudily uploaded. . . i have used and compared https:// att login line in two different browers the denial of access is and was still the same. I did however, do reading on ssl, and certification expiring. The only extremely minor differences were found under inspection and those were non-event items, like advertising banner width. 

And if know some handy-dandy programming work-around to bypass in user name log in is false thereby denying access, bring it on. Print the code, the registery edit, the bat or dat file. TRULY claim title of SOLVED SOLUTION. Be King for a day.  

You have your belief on cookies i have mine. You deny the existence of temp internet files, i know they exist. To both of these points WE WILL AGREE to disagree on the cookie & temp file issue because frankly, those two background programming issue are NOT a major life activity of concern. Good day enjoy your evening

Completely incorrect.  PERIOD.  Some illustrations here.

Temp internet files are little bits of info gather from the various sites visited

Yes, those are your site cookies - AND THEY ARE STORED IN THE BROWSER'S PROFILE as I've repeated been stating.   Flash cookies are stored system wide but aren't pertinent to the problems stated here.

i know i have used temp internet files to retreive data - and are a stored cache on your computer until deleted.

On most OSs there is a system wide data cache and a per user cache but again they have no effect on a browser's behavior.  Even cache data is tied to the app that created it.

The sbcglobal acct start working after I got an OAuth.

OAuth or the secure mail key?   You couldn't have been using both unless OAuth also (now) accepts the secure mail key.

...when they shifted all the real MaBell accounts into yahoo with its aol viral programming.

Att is not shifting the legacy accounts to yahoo, they are unmerging them from yahoo -- or at least attempting to.  That's what's causing all these account problems.

...when they shifted all the real MaBell accounts into yahoo with its aol viral programming.

While the accounts are being unmerged from yahoo att still uses yahoo as their email service provider and as such unfortunately and apparently subject to their terms of service (TOS).  Since yahoo is a subsidiary of OATH (not to be confused with OAuth security), and so is AOL, att is also under OATH's TOS as well and its TOS that can be considered the most insidious given they say they are going to mine all your email for all it's worth.

You have your belief on cookies i have mine. You deny the existence of temp internet files, i know they exist. To both of these points WE WILL AGREE to disagree on the cookie & temp file issue because frankly, those two background programming issue are NOT a major life activity of concern.

I explained above cookies and caches.  Mine is not a believe, it is fact.  You care to not believe it.  Fine, so as you say, we'll agree to disagree.

Just set up a new email at a att.net address and received "welcome" notice upon completion. We have an older fully functional email acct.at a bellsouth.net address. When trying to access the new acct. at att.net I receive a SAML.2.0 authentication failure screen notice. What is this and what can I do to access and use the new email acct.?

Hello there, @ttowndc.

There is currently a known issue with email accounts receiving an SAML error when attempting to access webmail. Some users have had success downloading their mail via a mail client using IMAP, so we believe you might as well.

We are currently working towards a resolution for the SAML errors, and we appreciate your patience while we investigate.

If you have any other questions about AT&T products or services, we're always happy to help.
