On this page, talking about the Upload Folder State, we have a note which references the constant UPS_ONE_FOLDER. This constant is not defined in our list of MAPI Constants or in a header file. This is an oversight. Here’s the definition for this constant:
#define UPS_ONE_FOLDER 0x00000004
That is all.
Any hints as to how to use this?
I seem to get a MAPI extended error (without error text) when I try to go into the upload folder state from the sync state.
Is the feid which is mentioned in the upload folder state page set on the SYNC structure - (the FEID field marked as reserved in the docs). Are the other fields (pel etc.) blank?
