+ The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
+ The remote certificate is invalid according to the validation procedure.
As you see here, The remote certificate is invalid because the URL used which is localhost doesn’t have certificate.
- Just click on Certificate error in browser
- View Certificates
- Issued by is the actual FQDN to be used
In my case it is EXCAS01, So I changed the URL from https://localhost/ecp to https://EXCAS01/ecp
Now you can download PST without any issues.
