Symptoms
OA supports multiple mailbox stores per Exchange Backend server. The article describes how to configure OA to provision customers' mailboxes on different Exchange mailbox stores using provisioning attributes.
Resolution
Create and register new mailbox store in OA using the article #1178 How to create additional Mailbox Stores for Hosted Exchange.
Create provisioning attributes, e.g.
exchange_2
andexchange_store_2
.Note: we will use
exchange_2
as a provisioning attribute and it will be assigned to Exchange hosts, whileexchange_store_2
is a mailbox store attribute and it will be used within Service Templates and assigned to Exchange mailbox stores, not hosts.Create new resource type based on the Hosted Exchange resource class and assign the
exchange_2
provisioning attribute to it.Create new Service Template for Exchange hosting, include resource type created on the previous step into it and define the value of the
Mailbox storage attributes (comma-separated values)
template parameter asexchange_store_2
.Assign the
exchange_store_2
attribute to the new Exchange mailstore in OA Provider CP at Service Director > Hosted Exchange Manager > Mailbox Stores > select store > Attributes tab.Assign the
exchange_2
provisioning attribute to the Exchange server where the new mailbox store is created.Note: Exchange host with ExchangeSMTP service should have the same provisioning attribute assigned as well.
- Mark the new mailstore as
Ready to provide
in OA Provider CP at Service Director > Hosted Exchange Manager > Mailbox Stores > select store > General tab.
Additional information
OA is looking for the target Exchange mailbox store for provisioning this way:
OA detects the provisioning attribute of Resource Type
Hosted Exchange
from Service Template (exchange_2
in the example above).OA selects the Exchange BackEnd and FrontEnd servers with the same provisioning attribute (
exchange_2
).Detects the mailstore attribute from the
Mailbox storage attributes
activation parameter of Service Template parameter (exchange_store_2
in the example above).Selects the specific Exchange Mailbox Stores by mailstore attribute and select the one which has maximal not allocated size.
- Provisions new mailbox on the selected Mailbox Store.
