A recent question in the Microsoft development forum for Exchange was how to get information about mailboxes on Exchange 2003 from an ASP.NET application.
The simplest solution is to use WMI in this case. Exchange exposes certain mailbox statistics via the Exchange_Mailbox WMI class. The following code can be used to iterate through all mailboxes and print some of the properties:
1: using System;
2: using System.Management;
3:
4: namespace MailboxSizer
5: { 6: class Program
7: { 8: static void Main(string[] args)
9: { 10: var scope = new ManagementScope("\\\\.\\root\\MicrosoftExchangeV2"); 11: var query = new ObjectQuery("select * from Exchange_Mailbox"); 12: var searcher = new ManagementObjectSearcher(scope, query);
13: foreach (ManagementObject mailbox in searcher.Get())
14: { 15: Console.WriteLine("Display name: {0}", mailbox["MailboxDisplayName"]); 16: Console.WriteLine("Size: {0} bytes", mailbox["Size"]); 17: Console.WriteLine("Storage Limit: {0}", (StorageLimitInfo) (uint) mailbox["StorageLimitInfo"]); 18:
19: Console.WriteLine();
20: }
21: Console.ReadLine();
22: }
23: }
24:
25: [Flags]
26: internal enum StorageLimitInfo
27: { 28: BelowLimit = 1,
29: IssueWarning = 2,
30: ProhibitSend = 4,
31: NoChecking = 8,
32: MailboxDisabled = 16
33: }
34: }
You need to reference the System.Management assembly for this code to work.
