I need to create several storage groups for a whole bunch of companies that will be using my server. To set this up I went into Exchange System Manager, right click on Server, New Storage Group, type name, click OK. Then right click the new Storage Group, New, Mailbox Store. The following error comes up: “Group already contains the maximum number of stores allowed” . What am I doing wrong? The Storage Group is empty and still same message. Forgive me if the answer is obvious, I’m new to Exchange 2000.
