Attributes for Exchange 5.5 Mailboxes : DXA-Task
This is the third degree of the size limits for this mailbox (in bytes). If this limit is exceeded neither sending nor receiving of mail will be allowed for this mailbox.
|Heuristic||12 => Replicated between sites, Operational attribute|
Admin access only
|Ex55 Database name||DXA-Flags|
If the mailbox user exceeds this limit he won't be able to send or receive mails any more. The two other limit degrees for the mailbox size limit can be configured with the attributes MDB-Storage-Quota and MDB-Over-Quota-Limit.
If you want to put in force these limits, you'll have to set the attribute MDB-Use-Defaults to FALSE, otherwise the system uses the general limits which are a property of the regarding mailbox store.
The DXA-Task 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.
