Nebula Synchronizer

To use the Nebula Synchronizer the following requirements must be met:
Note: You can use our Checksite to automatically validate your environment, see this article 


SuperOffice Versions:

Other versions will be supported in a later stage.


Microsoft Exchange:

  • Microsoft Exchange 2010 (SP2 or higher)
  • Microsoft Exchange 2013
  • Microsoft Exchange 2016
  • Microsoft Office 365 (Business Premium / Business Essentials / Enterprise / Government plan)

Please note: Office 365 Home, Personal and regular Business are not supported, as these plans do not have the Exchange Online component. Compare the Office365 Business plans here.

Please note: IMAP & POP3 accounts are not supported. The IMAP/POP3 protocols do not have support for calendaring and only cover email synchronization.

Please note: Authentication using a solution like Citrix Netscaler is not supported.

Please note: 2-factor authentication is not supported. However, in Office 365 it is now possible to create an app password when using 2-factor authentication.
An app password is a code that gives an app (like Nebual Synchronizer) or device permission to access your Office 365 account.

If your admin has turned on multi-factor authentication for your organization, and you're using apps that connect to your Office 365 account, you'll need to generate an app password so the app can connect to Office 365. More info



The Exchange Autodiscover must function for correct configuration (KB article). Please make sure before signing up for an account!
When Autodiscover cannot be used due to technical or security reasons we have an advanced option where you can manually add the EWS (Exchange Web Service) and the OAB (Offline Address Book) URL's. More Info

  • G Suite (Basic, Business and Enterprise, more info)
