Some large attachments are not included in emails when exporting a report - Support and Troubleshooting

Some large attachments are not included in emails when exporting a report Description  Problem Exporting a report containing a large attachment like a CSV file with more than 25MB results in a dialog box with a " Mail it " option.

However, when clicked, the email message is generated without the expected attachment as it follows the limits on the outbound Email of the ServiceNow infrastructure.

Symptoms The issue is observed when a user clicks on " Mail it " and the attachment is not seen in the generated Email

Cause This is due to the limits on the outbound Email attachment size

Resolution Do not click on " Mail it " if large reports are exported. Instead, download the reports by clicking " Wait for it ". Note : You can increase the value of system property glide.email.outbound.max_total_attachment_size_bytes. However, if using the ServiceNow mail infrastructure to send these emails there is a hard limit of 25 MB ( total size of the email, including body and all attachments ) that can not be changed. You can use your own email infrastructure if you need to send attachments larger than 25 MB.
