email - 0x80040115 when trying to retrieve PR_DISPLAY_NAME

Question

My native raw C++ program uses MAPI to traverse the tree in the Exchange Server.

Sometimes when I call HrGetOneProp() on a IMAPIFolder* pointer to retrieve PR_DISPLAY_NAME it fails with HRESULT 0x80040115. It only happens for one particular folder, all other folders names are retrieved allright.

Outlook 2003 running on the same machine under the same user displays all folders, problematic one included.

What is the cause of the problem and how do I resolve it?

Answer 1

0x80040115是MAPI_E_NETWORK_ERROR。该文件夹可能是来自另一个收件箱的共享文件夹，您无法连接到它。Outlook 可能仍会正确显示它，因为它在某处缓存了该名称。
