Cause
This is due to a limitation on the size of attachments in Exchange or O365 can receive which may be defined by corporate policy. Please verify the 'MaxReceiveSize' setting using PowerShell or contact the Administrator.
Sample command to get setting:
$user = "username@corp1.cmtsandbox.com"
$cred = Get-Credential $user
$exSvr = "ps.outlook.com"
$strTemp = "https://" + $exSvr + "/PowerShell/"
import-module MSOnline
Connect-MsolService -Credential $cred
$Session = New-PSSession –ConfigurationName Microsoft.Exchange –ConnectionUri $strTemp -Authentication Basic –Credential $cred -Allowredirection
Import-PSSession $Session
get-mailbox $user |fl *quota*,*max*,*warn*
get-mailboxstatistics $user |fl *quota*,*max*,*warn*
Get-TransportConfig | Format-List MaxReceiveSize,MaxSendSize,MaxRecipientEnvelopeLimit
