I purchased a Microsoft Surface 2 for a few employees to use when on call. The email accounts that need to be on the device are shared, generic accounts. When on the users laptops, they work fine as the users are all set as "Send As" and/or "Send on Behalf of". Unfortunately, the Surface 2 can't be added to a domain. I am finding that when I add a shared account to Outlook on the Surface, it takes the credentials, and will receive, but when you go to send, it errors. A non-deliverable is returned with the address of the recipient stating the account doesn't have access. I tried re-adding the account, re-formatting the Surface 2, re-downloading the OAB, all to no avail.
How can I get around this? I assume its happening because there is no over-arching AD account that can be confirmed as authorized to send as? Currently the login to the Surface is just a basic local account.
