MS Office 365 OAuth authentication method can be used to authorize RGES Sync to access end users’ Office 365 mail data over EWS connection.
This method is also the only way to authorize an Exchange Impersonation service account for Office 365 mailboxes, since the old Impersonated access authorization method with login and password creds entry will be removed by Microsoft in 2021.
Users data access authorization by RGES via OAuth 2.0¶
You need to activate Revenue Grid Synchronization in the following cases:
- on the first start, if RGES Sync was not mass-activated by the local Admin, for example in case mass deployment through Exchange Impersonation cannot be used in your company’s configuration for any reason
- if RGES Sync’s mailbox access expired or your mailbox password was changed
Tip
In the latest RG Email Sidebar updates the users are prompted to enable RGES Sync for Office 365 on the first RG Email Sidebar logon
Follow the steps below to do that:
1. In RG Email Sidebar, click the ☰ (Menu) button in the upper left corner and select Set up sync (or Sync settings) in the Menu that appears
2. Enter your Office 365 login credentials in the O365 OAuth 2.0 dialog that appears
Next, Office 365 will request your confirmation; click Accept in this dialog to complete Sync activation. Your email data accessed by Revenue Grid Sync engine remains all secure and private, under our Privacy & Security principles.
After access has been authorized, RGES Sync will start running every 30 minutes 24/7 for this email account.
