Hi all,

I am using Indy 9 on BDS 2006.
I have written an application that uses the TIdIMAP4 component to connect to 
an MS-Exchange mail server.
I am able to open a mailbox and retrieve a message from inside it but when I 
try to delete the message once I am finished with it, the DeleteMsgs method 
returns false.
The call to ExpungeMailBox is successful, but it doesnt do anything because 
the call to DeleteMsgs failed.


I am not sure if I am using the method correctly and I cannot find any 
examples on the internet.

I include a code snippet.

Regards,

Andre'

{
  if (!IdIMAP41->SelectMailBox("barney"))
  {
    Memo1->Lines->Add("Unable to access mailbox");
  }

  int ii[1];
  ii[0] = 1;
  if (IdIMAP41->DeleteMsgs(ii,1))
  {
    Memo1->Lines->Add("Message Deleted");
  }
  else
  {
    Memo1->Lines->Add("Unable to delete message");
  }
  if (!IdIMAP41->ExpungeMailBox())
  {
    Memo1->Lines->Add("Could not expunge mailbox");
  }
}

The only way that can happen is if you are passing invalid parameters.

You are not.

That is not correct.  The second parameter is the index of the last item in
the array, not the number of items in the array.  You need to specify 0
instead of 1, ie:

    if( IdIMAP41->DeleteMsgs(ii, 0) )

Alternatively, use the EXISTINGARRAY macro instead:

    if( IdIMAP41->DeleteMsgs(EXISTINGARRAY(ii)) )
