Content Approvals notification email not sending


Still working through an issue where our Episerver notifications don't seem to be working. When testing the Content Approval I found this in the Episerver INFO logging:

2021-05-07 19:53:06,521 [37] INFO EPiServer.Notification.Internal.DefaultNotificationDispatcher: No Provider found that matches user preferences to send a message on Channel("epi-approval")

Does anyone know why this is happening? I've never had to configure anything special on other projects from memory.

We're using:

  • EPiServer.CMS 11.20.6
  • EPiServer.CMS.UI 11.35.1

Can you search in your solution if you have any customer formatter is implemented for channel "epi-approval"?

Hi Praful

Thanks for the reply. I've searched our code base and there is nothing with "epi-approval" - do you think it's not out of the box from Episerver?

We've not written any custom notification code on this project - we're just trying to get out of the box Content Approvals email notification to send. I have a feeling it's related to the fact we're using AAD B2C but I'm not sure if it is yet.

I think I found the fix for it. This post here seems to be the exact same issue Working Around IQueryableNotificationUsers when using external cl ( (they're also using AAD) and their solution appears to be working on my local.
As the post says, this might be an Epi bug where it gets the incorrect IQueryableNotificationUsers implementation "AspNetIdentitySecurityEntityProvider".

Good to hear that you got a fix. :)

Alright, so from discussions with Epi support on this the fix that avoids this work around is to simply remove the package "EPiServer.CMS.UI.AspNetIdentity". After doing so the problem has gone away completely for me. So if you don't need this package I recommend removing it.
