Currently we are experiencing an issue with CRM regarding an update from CRM 2013 to CRM 2015.
Initially we upgraded the organisation to 2015, and found that everything except for the email router was working successfully – so we have tried numerous workarounds. We then discovered that in the CRM Deployment Manager, it stated that our update had failed. We are currently using this organisation daily, and apart from the email router, you would not think there was a problem with it. We have a test organisation, that we also upgraded – however this one was successful – we tried the email router with it and it works perfectly.
Is there a way that we can ‘re-upgrade’ or successfully upgrade the original database, so that we can use the email router?
To confirm, the image below is what we see in the Dynamics CRM Deployment Manager:
