Hi again Zohaib_Yousuf
I think I found what the issue could be, I took a look at your original screenshot again and noted that your MaxSendLimit on the Organisation level is set to 35 MBAccording to this documentation, external recipients that send emails to your organisations are targeted by this limit as well, see the screenshot below
With this in mind, I believe that if you change the MaxSendSize to the wanted value these NDR´s should stop.
Set-Transportconfig -MaxSendSize "45MB"
Let me know if that helps

HiZohaib_Yousuf !
Have you checked the recipients mailbox so that it doesn't have different limits set on it?
Get-Mailbox -Identity "Mailbox Name" | fl MaxReceiveSize
Have you also verified if any Transport rules might set other limits?
Is the recipients mailbox in Exchange Server or Exchange Online?
Is your Exchange server the first point of contact in your email flow?
Let me know if further assistance is needed!
Kind Regards
Oliwer Sundgrenissue is just on-premise exchange users. Just on-premise user unable to receive email more than 35 MB. no issue on exchange online users.
