Is there any way to read via Microsoft.Office.Interop free space left in default Mailbox ?
(So the same info what is displayed in Outlook's down left corner - as shown below)
You can try to read the following properties using Store.PropertyAccessor.GetProperty()
:
PR_QUOTA_RECEIVE
(DASL name http://schemas.microsoft.com/mapi/proptag/0x341C0003
)PR_PROHIBIT_RECEIVE_QUOTA
(DASL name http://schemas.microsoft.com/mapi/proptag/0x666A0003
