I have four companies that are merging and want to merge their office365 accounts. They want to be able to see the same share point folders and see the status of employees in each organization (available, offline, etc...). Also two of the companies have exchange online two use google docs. How can I get all 4 onto one exchange online that can be centrally managed?
This is all simple in my mind but I may not be explaining very well. Any help is appreciated.
