We have an environment in 6.0.1 version . I was looking out for some system property which would set the default value of "Connection Streams" and any custom streams for all users to "true". I have seen few properties related to action queue and moderation queue but nothing related to "stream".
If anyone knows about this please provide your input. Any help on this is much appreciated.
I found these pages with a few clues
The specified item was not found.
And ended up adding this system property to our Jive 220.127.116.11 external site and it worked to have the Connections Stream email turned on for all new users by default. (It was off by default previously.)
notify.connections.external.default.preference = true
