Limit for Public Folders has been exceeded in Active Directory forest.

Those limits are described in Microsoft Technet article: Limits for public folders.

We strongly recommend to monitor the total number of customers with public folders in an AD forest, and make sure it does not exceed 100.

We are working on the OA Hosted Exchange Module architecture change that would address this issue. The Feature Request is POA-85648. Please contact your Account manager to trace the status.
