Could not find configuration node: "exm/eds/senderManager"
This can be solved by ensuring the Sitecore.EDS.Core.config (located in \Website\App_Config\Include\EmailExperience) configuration file is enabled.
However if the error is appearing on a content delivery instance, the configuration file above should not be enabled. You should check that only the following email campaign/email experience DLLs are present in the bin folder:
- Sitecore.EmailCampaign.Cd.dll
- Sitecore.EmailCampaign.Content.dll
- Sitecore.EmailCampaign.dll
- Sitecore.EmailCampaign.Model.dll
- Sitecore.ExM.Framework.dll
It's also worth checking that only the following configurations are enabled in the \Website\App_Config\Include\EmailExperience folder:
- Sitecore.EmailExperience.CommitSession.config
- Sitecore.EmailExperience.ContentDelivery.config
- Sitecore.EmailExperience.Core.config
- Sitecore.ExM.Framework.config
- Sitecore.ExM.Framework.ContentDelivery.config
Either of the above solutions should solve the error for you.
