"The account does not have permission to impersonate the requested user - Unity

[Process153]

Yet another question....  Was wondering if the account its referring to is the account used to access exchange in the unified messaging service set up?  I've already added it to the role in exchange so it should have permission...

Thanks for any ideas!

You'd need to assign appropriate rights to your service account, sot sure what exchange version you have but here are the details:

Thanks Leszek,

Yeah, tried that and get the usual command cannot be found from Powershell shell

Ah! You have to be a member of the Exchange Organization Administrators group!

Hopefully this will help someone else:

Thank you Process153, this pointed me in the right direction since we use O365. Below is the non PowerShell way to implement that new Role needed for (applicationImpersonation).
