Attributes for Exchange 5.5 Mailboxes : MDB-Storage-Quota
This is the first degree of the size limit configuration for the mailbox (in Bytes).
MDB-Storage-Quota
| LDAP name | MDB-Storage-Quota |
| Data type | Integer |
| Multivalue (Array) | No |
| Heuristic | 12 => Replicated between sites, operational attribute |
| Access category | Admin access only |
| Ex55 Database name | MDB-Storage-Quota |
If the mailbox user exceeds this limit, he will receive a warning mail from the system informing the user about this issue. The two other limit degrees for the mailbox size limit can be configured with the attributes MDB-Storage-Quota and DXA-Task.
If you want to put these limits in force, you will have to set the attribute MDB-Use-Defaults to FALSE, otherwise the system uses the general limits which are property of the regarding mailbox store.
The MDB-Storage-Quota attribute is an operational attribute which is not automatically retrieved by a GetObject() or an GetInfo() call. You can load such attributes into the object property cache by explicitly calling GetInfoEx(). Read more about this technique in the topic 'Reading object attributes' here in the SelfADSI tutorial.
