How to add an email account to a user via workflow

so it looks like edsaCreateMsExchMailbox = TRUE does not work

I'm getting an error  "Administrative Policy returned an error. Exchange Server-related operation failed. Object reference not set to an instance of an object"

Can you share how you've implemented this?

I used the Update activity and setting the Mail and Alias attribute (Based on the pre2000 login)  save the attribute  then set the create mailbox attribute

Mmmm... though probably not the source of the error, the contents of 'mail' are determined by your Exchange org's addressing policy so you should not be trying to set the mail attribute.

Does your Active Roles service account have Recipient Management permissions in Exchange?

The account does have permission i tried removing the mail attribute still the same error
