Single Sign-On for Exchange Online

    Question

  • Hi,

    Recently, we have subscribe to Office 365 - Exchange ONline for Single Sign On.

    Now we are looking to implement the Single Sign-On capability so that users need to log in only one time to access both, the corporate and the Exchange Online resources. Based on reading, this can be achived using Active Directory Federation Service 2.0.

    1. Refering to the Implementing your AD FS 2.0 Design Plan. For the purpose of achieving Office 365 (Exchange Online) SSO using AD FS 2.0, which of this design - the "WEB SSO" or the "Federated Web SSO" should we be following?

    2. Is DirSync a requirement for implementing Office 365 SSO with AD FS 2.0. 
    It is not mentioned in either of the Plan for and deploy AD FS 2.0 for use with Single Sign-On or the Prepare for Single Sign-On article whether the 'Active Directory Synchonization/DirSync' tool is a requirement.

    Thanks in advance.
