Synchronization with Exchange Online

Connector SE uses Application Impersonation over EWS in order to access Exchange Server – therefore an ExchangeOnline Edition (e.g. Plan E1or Plan E3) is required, which includes this feature.

See http://www.microsoft.com/en-us/office365/compare-plans.aspx for a comparison of the different plans (editions) of Exchange Online.

After creation of the impersonation account the role Application Impersonation can be granted to this user either via PowerShell (See Working with application impersonation in Exchange Online (see http://msdn.microsoft.com/en-us/library/exchange/gg194012(v=exchg.140).aspx) for further details.) or via GUI (See http://exchws.wordpress.com/2011/12/13/activate-user-impersonation-in-office-365-for-exchange-online/ for further details.).

The URL of the Exchange Online Web Service is built like https://" + <Server Name> + "/EWS/ Exchange.asmx. You can see your <Server Name> when logging into Exchange Online using OWA in the options of your account.
