ActiveSync should work on OpenBSD out of box.
A POSSIBLE quick fix: open file /etc/nginx/templates/ssl.tmpl, list 'TLSv1.1' in parameter "ssl_protocols =", then restart Nginx service.
If it doesn't work, I need relevant log for troubleshooting:
*) Which Android OS version are you running? And which app do you use for activesync client?
*) How did you setup the activesync on Android and Outlook?
*) What's the error message you got on Android and Outlook? please show us the original error message.
Hi Zhang,
I tried adding TLSv1.1 as you suggested and then retested Outlook 2013 and it had the same result. I have attached the screenshot for what happens. I have blotted out the mx name and IP address but the result from nslookup is correct, considering the error I thought I would include that and mention its correct.
1) Android 7.1.2 LineageOs with the default Android Mail App
2) I followed the instructions in the documentation for each Android as well as Outlook 2013
3) See attached screenshot for the Outlook 2013 error and as of the Android Mail app the error is: "Couldn't finish: Can't connect to server"
In /var/log/sogo/sogo.log I see the following after each attempt. I verified that on my firewall no request is blocked too.
