Is there any place (manual) where I can see what I should to in order to implemente solidcp in a dag server?

SolidCP in a dag is pretty much the same as single server besides that you fill out the dag name in the Exchange properties (like: DAG, not DAG.domain.local)

SolidCP server will still stay on 1 exchange server local fqdn due to a permission issue with Exchange virtual powershell dir from a remote location.

And what is your answer regarding the system create automatically the organization?

In my first testing, just after the creation of the hosting space I had to create the organization

I found where it was the mistake. I write it down badly the DC server for one of then

Now it works great

Regarding the creation of the organization automatically I just realise the box that I have to uncheck when I create a new hosting space

Thank you very for your time

Glad you have resolved the issue.

And yes you can chose to create org auto or not with checkbox in the hosting space creation page (if you have websites/ ftp / etc it will also show up there to check/uncheck).
