2794421 - Inbound and Outbound E-mail Size Limit


You would like to understand the size limits for e-mails received and sent via a service ticket.


 SAP Cloud for Customer


When working with inbound and outbound e-mails in a service ticket, the current size limit for inbound e-mails is 30MB and outbound is 25MB of data.

This data includes:

  • E-mail Body;
  • Attachments;
  • Fonts & Design;
  • Text;
  • Any additional aspect that will compose the e-mails itself;

E-mails which have more than 20MB may experience performance issues and experience issues within the system, causing it to fail and be displayed in the Web Service Message Monitoring tool as erroneous.

Please note that if the E-Mail is being rejected at our infrastructure side, there is no message displayed in the Web Service Message Monitoring tool. However, you receive an undeliverable response with the message ''5.1.0 - Unknown address error 552-'size limit exceeded''.

These email size parameters mentioned in this document are set by standard and cannot be changed. This is to keep the performance of the cloud servers.
