Outlook attachment's date modified

[Cedric]

Hello,

Is there any way to get the date modified of an Outlook MailItem Attachment
file, short of first saving it in the filesystem (Attachment.SaveAsFile) then
using .Net File.GetLastWriteTime?

This would be prohibitively expensive if the attachment is big.

Thanks.

If you're using an API other than the Outlook object model you can get the
properties of the attachment that aren't exposed in the object model such as
PR_CREATION_TIME and PR_LAST_MODIFICATION_TIME. Those properties are
available if you use CDO 1.21 or Extended MAPI (C++ or Delphi only) or
Redemption or another MAPI wrapper library. CDO and Extended MAPI also
aren't supported for use with managed code.

If you are using Outlook 2007 you can use the PropertyAccessor object of the
Attachment to get the PR_CREATION_TIME and PR_LAST_MODIFICATION_TIME
properties.

Otherwise you have to save out the attachment to the file system and get the
properties that way.

Thanks,

I tried to find that property with MFCMapi but it didn't appear.

Nonetheless, it works!
