The operation 'DATA' has timed out. Timeout '100000' has been reached

Hi Support,

While sending email with attachment of size 12mb, i faced “The operation ‘DATA’ has timed out. Timeout ‘100000’ has been reached.” problem
I used latest version of Aspose.Email.dll, v16.12.0.0.

Please suggest me how to fix this problem. Please update me ASAP.


Hi Munish,

Thank you for your interest in Aspose.

Please try increasing Timeout value for the client you are using to send messages. If that doesn’t resolves the issue, please share with us which client exactly you are using i.e SmtpClient, EWSClient etc. We’ll analyze the issue further and guide you accordingly.

Yes, I set max size of interger, its working fine.


Hi Munish,
