hello,

when I assign a task to another user I get an error, the process stucks on this system job "SendEmailWhenTaskAssigned"

and here is the details of the error :

"Workflow paused due to error: Unhandled Exception: Microsoft.Crm.CrmException: User does not have the privilege to act on behalf another user.

at Microsoft.Crm.BusinessEntities.SecurityLibrary.VerifyUser(Guid user, ExecutionContext context)
at Microsoft.Crm.BusinessEntities.ExecutionContext.SetCaller(Guid callerId, Boolean setCallerLanguage, Boolean verifyUser)

I would think twice about configuring CRM Service Accounts to be CRM users as well:

Microsoft Dynamics 365 services and application pool (CRMAppPool) identity accounts must not be configured as a Microsoft Dynamics 365 user. Doing so can cause authentication issues and unexpected behavior in the application for all Microsoft Dynamics 365 users:

If this hasn't been resolved already, I'm guessing the delegate permissions would also need to be set at the Exchange level for the mailbox?

Thank you all for your answers.I am close to find the solution.

the admin user who runs Asynchronous Processing Service can successfully run the process which sends the email to (assigned to )user.

the problem still persist to other users.

any ideas ??

Check to see if the user is assign to any Teams and Security Roles.

Make sure that user only has one Security Role and one Team.

Otherwise CRM sometime get confused in which Security Roles or team to use.

Does workflow runs on logged in user or some service account? If workflow runs under common user account may be that account missing "Act on behalf" privilege.

Error comes when a user does not allow the other user to send email on his behalf , so you need to allow with user you want to send email

File ->option -> Email -> check the below option -> click ok
