I ran into this same error for send email from Outlook VBO (BP 6.5), and I had to do an ugly workaround for it.
Created input Profile on the stage for the Outlook profile
oNS.Logon(<profile name>, <password optional, left blank>, <show dialog set False to avoid profile chooser>, <new session set to True, because this is the only Outlook session running>
I drilled down into the Send Email code stage and added the middle two lines
exsting -- Dim app = CreateObject("Outlook.Application")
me-- Dim oNS = app.GetNamespace("MAPI")
me-- oNS.Logon(Profile,,False,True)
existing-- Dim mail = app.CreateItem(0)
Not sure if this is something you can implement/have implemented and there are better ways to do it. Hopefully, this is helpful.
