Using Exclaimer Signature Manager Outlook Edition with Office 365

How does Signature Manager Outlook Edition work?

Signature Manager Outlook Edition creates an email signature for each user and adds it to their Outlook automatically, with details completed by taking them from their profiles in the Active Directory database.

This means you need the following to use Signature Manager Outlook Edition:

  • Outlook 2013, 2010, 2007 or 2003.
  • A Windows Server 2012, 2008 or 2003 Active Directory database.

Maintaining a coexisting Active Directory and Office 365 Directory

Many Office 365 plans incorporate a local Active Directory and they also provide functionality for synchronizing your local Active Directory with your Office 365 directory in the cloud.

Check the details of your Office 365 plan to see what features are available for your organization or contact Exclaimer Support (

Active Directory Synchronization

This Microsoft component synchronizes your Active Directory and Office 365 directory such that changes to the former are automatically propagated to the latter. Office 365 plans differ on whether they offer Active Directory synchronization, consult the details of your plan to confirm whether yours does.

Active Directory Synchronization plus Federation Services (AD FS)

Adding the ADFS Microsoft component to a synchronized environment allows end users to access both local and online resources through a single on-premise validation at logon. This solution provides the best of all worlds in that the administrator need only maintain one set of credentials and the end user only needs a single logon to access all the resources they need.

Users can still access Office 365 resources such as email even when outside of their on-premise environment using their online credentials.

    Always leave this on ‘auto-discover the Exchange Web Services URL (recommended)’ with Office 365.

    The Exchange Web Services URL tells the system where to find required Exchange data. On a correctly configured system, this URL is easily found using auto-discover (a Microsoft technology). However, for particularly complex or incorrectly configured systems, auto-discover may not work and so details must be entered manually.

    Use this URL for Exchange Web Services.

    If the auto-discover option fails to detect the correct URL for Exchange Web Services, select this radio button and enter the required URL in the associated field.

    For Office 365 the generic EWS address is
