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.

I appear to be working now and receiving emails from school . Thank you .

Hi Doorbers1, I'm told that they've fixed the block that was preventing the school from sending. If you could let me know if it continues to be a problem.

We know about anything before thursday at 1:30pm . Its only the mail sent after that they are investigating. If you have the timestamp for any of those please let me have it.

The last time I received email from that domain and it was received normally by me was 16/04/24.

Since last Monday(22/4/24)  and up to and including today none of the emails have got to me .

I had it investigated for the address provided and the team advised that we hadn't seen mail from that domain since before the fix was put in place. They have asked if the school can provide the time stamps of the sent mail.

Hi Ady,

The workplace has just tried again and it’s still failed , not coming through . This was literally in the last 5 minutes.

[Ady-TalkTalk]

Hi Doorbers1, we've checked and the last time we were sent mail by the biddulphhigh domain was before the fix was put in at 1:30pm yesterday.  Could you ask them to retest again?

Thanks @Ady-TalkTalk    Seems to be working for now.

I've had confirmation that this issue should now be behind us. Please let me know if you are still being advised that mail cannot be sent due to TT992 errors.

Hi PotPits, I've added your sender to the list.

I have been following the thread of messages with regard to the above as I too am having problems.  One of my contacts has reported to me that they are receiving TT992 bounce back messages when emailing me.   I had received email from the sender having these bounce back emails during the day of Friday 19th April 2024 and their first bounce back TT992 was received later in the evening of 19th April and ever since.

This is just one of the bounce back messages that has been received when trying to email me.
