Hi,
The 0x80004005 could also occur if the DLLs required are missing.
The MAPIEx files must reside in the same directory as the Blue Prism program files (typically C:\Program Files\Blue Prism Limited\Blue Prism Automate). If they are installed to different directories, the MAPIEx functionality will not work when attempting to access an Exchange server from within a business process. As such, the DLL files in the MAPIEx installation directory should be copied to the Blue Prism installation directory before use on a particular resource.
The Visual Business Object expects that the Blue Prism installation directory, where the DLLs it uses are found, to be C:\Program Files\Blue Prism Limited\Blue Prism Automate. If the installation directory is slightly different, i.e. C:\Program Files (x86)\Blue Prism Limited\Blue Prism Automate, the reference to the MAPIEx DLL in the VBO must be altered to use the different path. After importing the Blue Prism MAPIEx object, open it for editing in Object Studio, and within the Initialize tab, double-click the business object properties stage. Navigate to the Code Options tab, and alter the path to BluePrismMAPIExAutomation.dll in the External References list.
Hope this should work for all of you.
