[EmailException] "Error creating Email. The operation has timed out" in 100s


I'm getting timeout from timer that sends an e-mail. The timer fails at 100 seconds. This e-mail has a query executing in preparation. If the query execute in 99s the process ends successfully.

I looked for this configuration in service center but with no success. Is there a way that I can change this timeout?


OutSystems.HubEdition.RuntimePlatform.EmailException: Error creating Email. The operation has timed out

Hi Joao Oliveira,

Please check the server configuration values:

  1. QueryTimeout
  2. RequestTimeout
  3. SessionTimeout

I usually find this configuration on server file : /etc/.java/.systemPrefs/outsystems/prefs.xml 



Hi Shamil,

Thanks for your response.

I'm using OutSystems with C# so I can't find that file. 

I found this timeouts:

  • Query timeout: 1200
  • Execution timeout: 300
  • Session timeout: 1200

Best regards,



Hi João,

You can't change the timeout. Check this post for more information.
