Extensions for Supporting Exchange Hybrid
The necessary database extensions for mapping an Exchange hybrid system to the One Identity Manager database are in this Exchange Hybrid Module. A new table EXHRemoteMailbox is added for mapping remote mailboxes and certain relations linked to it as well.
The necessary connector extensions and default project template modifications are installed with the Microsoft Exchange Module.
For more detailed information about mapping remote mailboxes, see the One Identity Manager Administration Guide for Connecting to Microsoft Exchange.
Take the following into account when synchronizing Exchange hybrid remote mailboxes:
This connection is normally created automatically when the synchronization project is created for local Microsoft Exchange. This assumes that Azure Active Directory was already loaded in to the One Identity Manager at the time. You can establish this link manually at any time.
To declare the Azure Active Directory tenant in a Microsoft Exchange organization
Remote mailboxes are mailboxes that are declared in the local Microsoft Exchange environment but were added in an Exchange Online environment. These mailboxes can be added to distribution lists or be given sending limits in the local Microsoft Exchange environment, for example.
The Exchange Hybrid Module allows remote mailboxes to be created, edited and deleted in combination with the updated Microsoft Exchange connector.
There are the following different types of remote mailboxes:
To edit a mailbox
NOTE: After creating a new remote mailbox, a corresponding mailbox is not added in Azure Active Directory until the next time you synchronize your Azure Active Directory tenant in Exchange Online Connect. Up to this point, the mailbox is acknowledged in the local Microsoft Exchange environment but is not yet available for use.
NOTE: After new remote mailboxes of type "Remote user mailbox" have been created by Azure Active Directory or Exchange Online internal processes, an appropriate Exchange license must be assigned for resulting the Azure Active Directory user account,
To display remote mailboxes without Exchange licenses
A warning is displayed while setting up a new synchronization project for a Exchange hybrid environment:
The given Exchange Organization has an Office 365 Hybrid Configuration. However, the Exchange Hybrid Module (EXH) was not found in the database. It is recommended you install the Exchange Hybrid Module first.
The schema extensions for synchronizing Exchange hybrid are not declare in the One Identity Manager database yet.
Update the One Identity Manager and select the Exchange Hybrid Module as another module.
The following error message appears when synchronizing Exchange hybrid memberships with an existing synchronization project.
The schema type (RemoteMailbox) does not exist in schema (...)!
The Microsoft Exchange Module has already been updated. Therefore, the Microsoft Exchange connector recognizes the extensions for synchronizing Exchange hybrid. The Exchange Hybrid Module was not installed.
If you want to synchronize Exchange hybrid:
Update the One Identity Manager and select the Exchange Hybrid Module as other module.
If you do not want to synchronize Exchange hybrid:
Apply the patch with the patch ID VPR#28904 to the synchronization project. This patch modifies the member filter's excluded lists.
For more detailed information about updating synchronization projects, see the One Identity Manager Target System Synchronization Reference Guide.
