We are working on an API based integration for a couple of our clients - this will disassociate emails from tickets and deals where the source is unknown (appears to be the default for email from Outlook) unless the ticket or deal ID is included in the subject line, e.g. (#1234567).
Would be keen to hear if anyone sees any issues with this approach as we are still trying to work through a few use and edge cases.
Also if anyone would be interested in this if we get it working?
