Thank you for replying Ken!

I tried to set the ConversationTopic field with VSTO, but this is a readonly
field. Do you know another way to set this field?

regards,
Koen

MailItem temp = ...
temp.ConversationTopic = ...

ConversationTopic Property:
Returns a String representing the topic of the conversation thread of the
item. Read-only.

PR_CONVERSATION_TOPIC can be modified, but the corresponding Outlook
property ConversationTopic is read-only. PR_CONVERSATION_TOPIC won't exist
on an item until it's been saved.

I modified PR_CONVERSATION_TOPIC using OutlookSpy and the change took
effect, but the original PR_CONVERSATION_TOPIC was still being displayed by
Outlook even after I exited and restarted Outlook. So you'll have to
experiment and see if changing the property does what you want.

Hey !

Is there a way to change the PS_CONVERSATION_TOPIC of a mailitem ? Or is
there a way to set this property before/instead Outlook set this property
to
the Subject (without RE/FW)?

We want to change the standard conversation management in Outlook and add
a
ticket number to a conversation. The implementation of Conversation Index
is
ok, but we want to give the conversation a specific name.

Thank you!
