The following code snippet fails when trying to save a mailitem to a windows
folder:

I've tried many variations of path - If i supply a file name I get an
"Invalid Parameter" error - so i'm pretty sure it just wants path - and when
I supply path (with \ or without \ as the last char) this is the error when
I get.

Here is an example of the code:

if(oItem is Outlook.MailItem)
{

Outlook.MailItem oMailItem = oItem as Outlook.MailItem;

oMailItem.SaveAs(path, OlItemType.olMailItem);

}

The error is:

{@"Can't write to file: c:\temp\outlook\Inbox\discover\testfolder.
Right-click the folder that contains the file you want to write to, and then
click Properties on the shortcut menu to check your permissions for the
folder." }

I checked the folder - and it is set readonly - I uncheck and apply - and
check the property again - and it is once again read only.

I only have problems writing to the folder through outlook and the interop -
I can write through the file system object - or manually through explorer,
or even through outlook directly....

I found this article which seems to explain perhaps why I can't remove the
'readonly' setting:

But still doesn't explain why outlook is the only program that has a problem
with that value...

Any help would be appreciated!
