Unable to gain access into Yahoo mail with Blackberry 9900

[sub101uk]

I was wonder if O2 have done some thing as I am unable to gain access to yahoo mail with my BB 9900 . I fully understand this is a very old phone and the browser and firmware is way out of date :

Bundle 7.1 2807 V7.1.0.1033, Platform 5.1.0.692

Portions of the browser are copyright 4thpass

This is the most updated firmware I could find .My problem is this when I try to connect to yahoo mail ,

I get this on my screen " There was a problem establishing a secure connection " ( stop or details )  If you press details you see this " Server Certificate Error Details " Domain Name Mismatch " Connection attempted to guce.yahoo.com This has been disallowed by your administraror "

The details are : -

I cleaned all the history and it was the same ? I reinstalled new firmware and reinstalled all my old mail and it was the same when you try to connect to https://mail.yahoo.com/neo/m/launch?reason=landshark using the browser .There was a problem establishing a secure connection " ( stop or details ) 

Now I do have a second BB 9900 and that connects fine to yahoo mail so it looks like the problem is with current BB 9900 .

I was thinking of doing a total reset on the phone and see if that has cleared the problem .

Any thoughts from any one ?

@sub101ukYou may have the wrong bolt on for the current phone

Probably best to contact customer services to see if can be reconfigured

If your other BB is running the same firmware and connects fine then it would certainly suggest that it's some sort of configuration error that a full reset may just fix for you.

Also @sub101uk Crackberry has some fixes

Hi Guys many thanks for all your replys its a pity I cannot do attachments on this site as I could do a screen shot and show you .

But for many years I have used a 9900 to access yahoo via my browser and all has been fine until now .But I am running out of options as I have clean all the browser data : From Passwords to Cache .

I reinstalled the firmware 7.1 Bundle 2807 (v7.1.0.1033 Platform 5.1.0.692 ) and reinstalled the mail and you still get the error message .

There was a problem establishing a secure connection .

Now if I try my other BB 9900 and contect to the yahoo URL it works fine via my home wifi which brings me to think that O2 are blocking me for some strange reason .

What I might try next is do a factory reset on the phone then try .

Many Thanks

Hi @sub101uk 

Did the factory reset help fix this, or did you find out more info since you last posted? 

[sub101uk]

I am still waiting to hear back from O2 regarding what is going on , If I dont hear any thing soon I will just do a factory reset and see if the phone is the same .

Or

Put my sim card in the other 9900 but I think last I tried this it was asking for a code . Will let you know what the out come is , When I did speak to O2 regarding buying a new BB since the old 9900 must be over 10 years old they said they no longer sold BB .So looks like buying a new BB on Ebay .

Thanks for all your help .

Things are still the same with my 9900 if I try to connect to yahoo mail I still get the same old message .

Hi again @sub101uk, and sorry to hear you still can't access your emails properly. I've checked on our end, and while O2 did not block you from using the service, since this phone is quite old, even Blackberry are not around to support from a manufacturer point of view.

Apps as they age will have expired certificates, but if you look here (info copied below), Yahoo have indicated that they will block older apps & this can vary which means that in time the other blackberry phones may also stop 

YAHOO:

Ways to securely access Yahoo Mail

By default, we block access to Yahoo Mail from outdated apps that could leave your account vulnerable. If we sent you an email indicating that your app is using outdated security protocols or you're unable to log in from an older app, you still have several options available to you.

Secure options to access Yahoo Mail

• Use the Yahoo Mail website: https://mail.yahoo.com.
• Install the Yahoo Mail app on your Android or iOS devices.
• Update or upgrade to the latest version of the third-party email app that you're trying to use.

Give temporary access to outdated third-party apps

While you switch apps or update your app, you can give the old app temporary access. Just remember, this is not intended for permanent access and you'll want to turn it off afterwards.

1. Sign in to Yahoo Mail.
2. Go to your "Account security" settings.
3. Turn on Allow apps that use less secure sign in.

Once the feature is turned on, you'll get regular alerts reminding you to turn it off. To do so, just follow the steps above and turn off "Allow apps that use less secure sign in."

Hope this helps!

Many Thanks for all your help it looks like I will have to go into the local O2 store here and see what deal they can do .

I have stuck with this account because I have unlimited internet access so I dont have to worry about how much data I use . Because a few years ago there was megger screw up and I ended up with 3 x £1134 bills , I did get a refund but soon after that I did change my BB account to unlimited . 

But I will check with the local O2 store and see what deals they have on the go .

Thanks again .
