VBA Run-Time Error '-2147221233 (8004010f)' - vba

Question

I am attempting to run the VBA code mentioned below.
The VBA code is for pulling email information from a single folder of the user's selection in Microsoft Outlook and listing what the response time is in Microsoft Excel.
Here is the error message I receive when I attempt to run it.
"Run-time error '-2147221233 (8004010f)':
The Property "http://schemas.microsoft.com/mapi/proptag/0x003F0102" is unknown or cannot be found.
Here is the code I am using:

Can you help me out? Please let me know if I could be any more specific.

Answer 1

I noticed that the error occurs on the only line using the "as string" in the declaration. Although this type of declaration if perfectly fine in VB, it doesn't work in VBA.
Simply remove the "as string" on that line.
