Emails not being received. Sender gets "Content rejected (TT992)" error

[Christo13]

When sending emails from a Microsoft365 account (this is my work account in a school) to my tiscali email address and they get rejected  with an undeliverable message stating Content Rejected (TT992).

I have asked our IT team at work for help and they have updated policies on the school system but emails sent still continue to fail to send.  I get an undeliverable message.

There are lots of similar reports with other people having the same issues.

Can TalkTalk stop blocking genuine emails.

I don't know what other emails are failing to arrive in my personal email account but other companies have sent letters in recent months asking me to update my email address as it is invalid but the address is valid, it is just TalkTalk rejecting the messages.

Thanks to those who've provided the sender domains. I've added them to the incident.

The issue is not resolved and I have missed e-mails from my car insurance company and local reputable garage. Both companies have e-mailed me many times in the past so this is a new e-mail problem that TalkTalk are taking too long to resolve. Other senders get their messages through but how many other e-mails am I missing?

Thanks @Ady-TalkTalk 

The senders domain is @thebaptistcentre.org  emails are being rejected from @talktalk.net

Me too, same problem.  Affected email @talktalk.net from @newlandjones.co.uk Please hurry up and get this sorted out!

Same issue, work emails from @amp-rose.com not arriving, undelivered message.

I also tried lots of test emails from family talktalk accounts and only 80% got through. The others are lost forever and worryingly I got no undelivered message, so I don't know what else has been lost and the sender doesn't realise

My sender is sending from ….@biddulph high.co.uk

Hi AJW73 and Doorbers1, please provide the senders email domain just the bit after @ symbol is needed. I'll then add them to the open incident.

Hi.

Is there any solution to this ?

I’m in a similar problem. Emails I’ve previously received fine from work are no longer coming to my inbox and being bounced back to sender with that tt992 code .

Spent ages on web chat yesterday with talk talk just going round in circles and no solution .

Hi Ady, Unfortunately the problem is not resolved.  The same error occurs as of 21:00 on 24/04/2024.  I think you know enough about it as loads of other people are posting about the same issue.  But here are details copied from the senders undeliverable message when sending from .....@chacademy.co.uk   to   ....@tiscali.co.uk  (email addresses redacted)   

cm7gb1 rejected your message to the following email addresses:

ra..........le@tiscali.co.uk (ra..........le@tiscali.co.uk)

There's a problem with the recipient's mailbox. Please try resending the message. If the problem continues, please contact your email admin.

I’m having the same problem. I’ve been on talktalk chat for the past 2 days and am no further on.  
All emails sent from my personal work email address (& from all my colleagues too!) to my talktalk.net email address are being rejected with the error code TT992

I seem to be receiving emails at talktalk.net from other addresses without problem - although who knows how many others are being rejected.
