PC WSPlus: Standard Response Buttons Unavailable

CAUSE

When Schedule+ version 1.0 is installed, it writes the following lines into the [Custom Messages] section of the MSMAIL.INI:

  IPM.Microsoft Schedule.MtgReq=3.0 ;;;;SchedMsg.DLL;;1111100000000000;;;;

  IPM.Microsoft Schedule.MtgRespP=3.0;;;;SchedMsg.DLL;;1100100000000000;;;;

  IPM.Microsoft Schedule.MtgRespN=3.0;;;;SchedMsg.DLL;;1100100000000000;;;;

  IPM.Microsoft Schedule.MtgRespA=3.0;;;;SchedMsg.DLL;;1100100000000000;;;;

  IPM.Microsoft Schedule.MtgCncl=3.0 ;;;;SchedMsg.DLL;;1100100000000000;;;;
				

If these lines are not in the recipient's MSMAIL.INI file, the header information and the buttons will not be available. If the lines are in the MSMAIL.INI file and are later removed, any undeleted meeting request messages will still be present and uncorrupted, but the header information and buttons will be unavailable.
