Note This article is applicable in a dedicated deployment of the Microsoft Business Productivity Online Suite.
You may have a custom application whose purpose is to pull information from Microsoft Exchange Server. This includes information such as Out of Office and Free/Busy data. However, the custom application cannot perform functions of this kind.
This issue occurs because the custom application has not been provisioned yet or is provisioned incorrectly. To perform functions of this kind, the custom application has to have Exchange Web Services (EWS) impersonation rights.
When your dedicated environment of the Microsoft Business Productivity Online Suite was deployed, a specific role group was set up to let you implement EWS impersonation rights. In the Self-Service Guide for Exchange Online, this role group is defined as follows.

If this role group was not provisioned for you, you have to file a new Change Request to have the role group provisioned.
This is how the role group will look on the Microsoft provisioning side:
The role group corresponds to a security group that you provision on your side. That group is the E2010-MSO Self Service - EWS Application Impersonation security group. After the role group is provisioned on the Microsoft side, you must make sure that the service account that the application is using is a member of the E2010-MSO Self Service - EWS Application Impersonation security group in your environment.
