Scenario: Send SMTP mail Message Activity doesn’t complete or even doesn’t timeout

This is random behavior.
but the strange thing is - send SMTP mail message activity doesn’t throw an exception or doesn’t’ timeout.

it just gets stuck. and this happens randomly.

has anyone else noticed this behavior?
any suggestions?

#2

Any errors in logs?

#3

No errors… it just gets stuck and then we have to kill manually…

#4

What smtp server are you using?

#5

we user Microsoft office365.com over standard port 587 with secure connection - StartTls
and also tried with auto.
Main problem here is that the activity doesn’t timeout or throwexception even after setting specified timeout duration, or even with default time out settings.
