RE: Convert Contact into a Lead
Hi,
Regarding your question about converting contacts to leads this is not supported.
After testing by our team, we have come up with the following possible solution.
The first step is to automatically create leads based on emails.
Second step, connect contacts to leads (since you have already created contacts, just connect contacts to leads)
For the first step, you can refer to the solution in the link below. But you still have to pay attention to the incoming and mailbox settings in the incoming queue and to the fact that if you use this method a lead will be created for all your MailBox history messages.

For the second step, you can refer to the solution in the link below. Creating a contact from a lead is easy, connecting a lead to an existing contact is very difficult.
