The Sting is not a valid TimeSpan value

I am trying to set the timeout period for an email with options.


I am using the standard ISO format of 'PT1D' as shown in the settings for my email action:

And yet I still get an error that this is not a valid TimeSpan value, is there something I am doing wrong here?

Hi ASolomon,


Not sure how is your flow configured. Could you show me a full screenshot of your flow configuration?

I am trying to reproduce this issue on my side.


Best regards,

PT6H works and so does PT48H 


maybe it does not like the D for day?

Hi LadyStorm,

The problem was indeed a syntax (ISO format) issue. Based on the Hint that we get on the UI of the flow, I was misled.

The rule is P (Period) T(duration) H (Hour) M(Minute) S(Second).

Thanks for your reply 🙂

I have the same issue, i was using PT2D and encountered the same error.  

I  have replaced my PT2D to PT48H, will know if this works soon enough 🙂
