  • is it possible to connect rpc over http having certificate but never connected to AD

    Hello,
    I have a situation where I have Exchange certificate previously used in Outlook used in AD but presently OS was reinstalled and there is no option to bring a laptop to the office.

    Is it possible to connect to EXCHANGE from fresh installed OUTLOOK on fresh Windows?
    I belive not because there is no domain profile on the computer.
    But may be there is a solution...

    Thx.
    Michael.

    RPC over HTTP does not require the computer to be on the domain, only that a domain account (with a mailbox of course) be used for authentication.

      so the certificate is enough for connecting to Exchange?
      sure that user name and password are valid. OWA is used for now.

        Should be, it'll be extremely slow to sync though, at least initially. Ideally I always setup RPC over HTTPS on the internal network, so that Outlook is fully synched via MAPI before configuring RPC over HTTPS.

            Easy enough to do -- e.g. work email on home PC

            Provide credentials in the form [email protected] and don't use NTLM authentication unless you have a vpn set up

              I agree with this. When this is not an option (i.e. setting up a remote user), I'll open a RRAS connection up when first registering Outlook with Exchange and performing the first sync, then setup the exchange proxy.

              In addition, I'll recommend to the user that they use the VPN connection whenever convenient, so that Outlook is communicating with TCP/IP instead of HTTPS. I've found this to give better performance... and when using a domain account you don't have to type in your password when opening outlook, just like as if you are on the LAN.

              I wonder if outlook would prompt for username/pw on a local account when the domain info is used in the PPTP client credential settings, I seem to recall networked drives working better in that situation...
