bounce error : message has lines too long for transport

I interacted with Microsoft Support earlier today and was able to resolve the issue by creating another Mail profile. The reference number to the ticket is: 1047219407

I tried with Thunderbird and it really works fine so it is all about outlook and microsoft is not keen to do anything with this.

I am using Microsoft 365 and saw this error started happening on all my computers. And yes only happens with existing emails but not with Hotmail email configured within Outlook but another email that is hosted through GoDaddy.

I am not sure if this is related but after over couple weeks of interactions with GoDaddy it seems like an issue with Outlook.

Why isn't anyone from Microsoft looking at this? Seems like pretty old issue but no interaction from Microsoft??

this is unbelievable.
I have seen hundreds of people having same problems (yes I am one of them too) and we are like a ping pong balls between the email providers and microsoft.

All these people are not using only one email provider and it is obvious people are facing this problem only when they use microsoft outlook but microsoft is still blaming the email providers rather than offerring a proper solution.

No error message occurs unless the email is replied by outlook and I never face with the same problem if I use providers' webmail or if I use any other email client but only microsoft outlook. It is really unbelievable that we are trying to convince Microsoft its their fault.
