  • Microsoft Solution for Hosted Messaging and Collaboration 3.5


You disable a user's access to Microsoft Office Live Communications Server in a Microsoft Solution for Hosted Messaging and Collaboration 3.5 organization. When you do this, the user's Microsoft Exchange Server mailbox plan reference is also removed. This condition causes any other operations that rely on the plan to fail. Additionally, Solution for Hosted Messaging and Collaboration 3.5 reports may contain inaccurate results.

By default, when Live Communications Server is installed in a Solution for Hosted Messaging and Collaboration 3.5 organization, all users are enabled for Live Communications Server access. If you disable this access by calling the DisableUser procedure in the HostedLiveCommunications namespace, Live Communications Server access is disabled for the user. However, the user's Exchange Server mailbox plan reference is also removed.
