Error sending mail message to SMTP server. Return code: 3

985 Views Last edit May 02, 2018 at 11:22 AM 2 rev

For one report with an Excel file in excess of 7Mb I get the message below.

All other excel files which are usually less than 2Mb are emailed without issue.

Error Message:

write error. [CrystalEnterprise.Smtp]: [Error sending mail message to SMTP server. Return code: 3.]

Report runs and downloads as Excel without any problem, it only fails when scheduled to email.

Thanks
