  11. hi thanks for your utube lecture but pleas can you recommend how i can learn office exchange online office 365 am a novice to this

  12. Hi, im trying to do this from a Windows 2003 server, but i do not have the exchange powershell installed, that are used to give permission to my user, as seen in the video at about 33:45 Can i install the power shell, for exchange on my windows server 2003?  or can i add the permissions somewhere else?

  13. Good video.. One question.. When can DirSync be installed to push AD passwords?

    Also, like the one user asked.. What about internal autodiscover?

  14. Hi, thank you for this wonderful documentation. I have a quick question –
    Upon setting up the Outlook profile (after pointing the MX record to 365) – How does Outlook manage to spot the 365 instance of Holy's mailbox and not the on-premise one first? Should we first point the autodiscover record to 365?
    In addition, the on premise server might be reachable by SCP, so how can we set up the new mailbox while connected to the organizational network?

    Please advise

    Thanks again!
