With the below command i did check for both the users its 25 MB

PS C:\Windows\system32> get-mailbox myuser@mydomain.com |ft Name, Maxsendsize, maxreceivesize

Name MaxSendSize MaxReceiveSize
---- ----------- --------------
My User 25 MB 25 MB

Do i need to check send/receive connectors.
Please advice

Check your send connector going to Exchange online its probably set to 10 MB

The users attachment is only 5MB.

do you trust a user to give you the correct information vs the microsoft error message?

Hi Flight,
Please confirm that the attachment size & O365 admin settings. if that attachment size is more than a limit as Microsoft defined. you have to compress the file or use any other source to transfer the media Like wetransfer etc
plz do refer the screenshot

hi,

 

for temporary solution for this issue u can ask user to upload the file/document to oneDrive  share the link to the required people

 

mean while u can check o365 admin portal settings & also please check the file which user required to send through mail by sending to your mail address & cross verify.
