Not currently. But you can give me some more informations:

a) What is the version of ucspi-ssl you have used (check the symlinked =
ucspi.h).
b) What is the OpenSSL/LibreSSL Version you are using?

In oder to diagnose TSL problems, disable TLS delivery to that address:

tlsdestinations:
!.outlook.com:

and see, what is happening.=20

Use=20

mconnect 104.47.9.33

to check the settings after responding with 'ehlo you'.

Best regards.
