Microsoft Exchange Shared Mailbox Additional Configuration Parameters
This section lists additional Microsoft Exchange Shared Mailbox configuration parameters:

Comma separated names of Shared Mailbox permissions which would be assigned to user when Shared Mailbox access is requested by using the memberOfSharedMailbox attribute. Default value: fullAccess, sendAs
For example:
<entry key="defaultSharedMBPermissions" value="sendAs,sendOnBehalf"/>
Permitted values: fullAccess, sendAs, sendOnBehalf

To avoid the intensive time process of reading users Shared Mailbox assignment except for aggregation operation, connector returns user’s Shared Mailbox values which were aggregated in the previous aggregation. This configuration attribute will get latest values of user’s Shared Mailbox assignment.
Note
Setting this flag to true has a performance impact on get account operation.
