I've recently begun using `evolution-ews` from the Ubuntu 19.10 repository and it's been working brilliantly. I've now attempted to do the same on a fresh Ubuntu 20.04 beta install and can no longer use the plugin to fetch my emails, as I get a TLS/SSL error.
I'm using it on an NHS email account with the server URL as `https://mail.nhs.net/ews/exchange.asmx` but when I add my email account I get an error message ``` SSL/TLS certificate for "mail.nhs.net" is not trusted. Do you wish to accept it? ``` The certificate is for *.nhs.net so should be valid, I also get a reported error "Error perfroming TLS handshake. The Diffie-Hellman prime sent by the server is not acceptable (not long enough) If I try to `Accept Permanently` the pop up box continues to reappear. ``` *.nhs.net Identity: *.nhs.net Verified by: GlobalSign RSA OV SSL CA 2018 Expires: 14/03/21 ``` ## On Ubuntu 19.10 (Working) ``` neil@thinkpad:~$ apt search evolution Sorting...
