This example shows how to provision a Microsoft Exchange 2000 or Exchange 2003 mailbox object in Forefront Identity Manager Synchronization Service (FIM Synchronization Service) with limits on the amount of disk space users are allocated to store their messages.
Attribute Inclusion List
You must select the following attributes from the Select Attributes property page for your Active Directory Domain Services (AD DS) management agent to provision an Exchange mailbox:
- mailNickname
- homeMDB
- mDBStorageQuota
- mDBOverQuotaLimit
- mDBOverHardQuotaLimit
- mDBUseDefaults
- msExchMailboxSecurityDescriptor
You can provision an Exchange mailbox with a mailbox store quota that limits the amount of disk space that the user is allowed to use to store their mail messages. When users exceed their mailbox store quota, they receive an error message warning them about their excessive space usage, but they can still send and receive messages. You can also provision the mailbox with an overflow quota that adds an additional amount of disk space to store their mail messages. When the user exceeds the overflow quota, the Exchange server does not allow the user to send email. Finally, you can provision the mailbox with a hard limit on the amount of disk space to store their mail messages. If the user exceeds this hard limit, the Exchange server does not allow the user to send or receive email.
The following examples show how to provision an Exchange mailbox. The mailbox is given a quota of disk space based upon the values of the mDBStorageQuota, mDBOverQuotaLimit, and mDBOverHardQuotaLimit attributes. You must add a reference to logging.dll to use the LogException method.
