@copy_writes Can you let us know what is the Dependency Version of the Mail.Activities package ?

@copy_writes It seems that there is a Bug in the Send SMTP Mail Message Activity starting from the Mail.Activites Package versions 1.9.4- Preview to the latest ones at which point the SecurePassword Property was introduced.

However I am not sure of this entirely, but you could make use of the Password (String) Property that is available in the Activity until a real fix is done.

Maybe the UiPath Officials can provide a better answer related to this issue.

I use this code to check the value I convert string secure to string new System.Net.NetworkCredential(string.Empty,StringPass).Password but
I get a null value why?

7

@copy_writes Can you replace String.Empty with Empty Quotes and check (“”) , Also is the Credential being retrieved from the Orchestrator ?

no, it’s not working still I get null value

new System.Net.NetworkCredential(“”,StringPass).Password

@copy_writes Can you expand the Assign Statement so that I could be able to look at the full expression, also Can you let us know what variable are you using in Get Credential as the Password Output ?

@copy_writes I think you would need to use strPass variable instead of the StringPass variable in the Assign Statement as you want to convert a SecurePassword (SecureString) to a String value.

Can you check and let us know the outcome ?
