I have some code that has been working until recently that used the mailitem ConversationIndex to track emails.
All of a sudden all mailitems are being created with blank indexes and IDs.
myMail = CreateItemFromTemplate(sTemplatePath)
debug.print mymail.ConversationIndex
Outputs blank!!!
Any ideas what I've screwed up?
You cannot expect the conversation related properties to be populated immediately after an item is created. It is reliably populated only after the item is sent.
