'Access Denied' in SetProp-ing a message   

Hi guys.
I have an IMAPIFolder in which I want to change some IMessages. I
successfuly use OpenEntry() with MAPI_MODIFY on the folder to get those
messages and can read the subjects, etc. However SetProp() on the
message fails with 'Access Denied' hresult.

Both the folder and the message have PR_ACCESS_LEVEL of 1 (which is
MAPI_MODIFY, so it's good).

Any ideas?
Thanks,
