After you selected Microsoft Office 365, you will be taken to the Office 356 connection settings step of the wizard. Specify the following:
- Region – select Microsoft Azure region the organization belongs to. Usually, this will be the Default region. However, you may need to choose Germany or China if your Office 365 belongs to the corresponding Microsoft Azure region. Such organizations will be displayed with an icon having the matching state flag next to it.
If necessary, contact the IT administrator in charge of your Office 365 deployment. To read more, refer to the Microsoft Azure site at https://azure.microsoft.com/en-us/overview/clouds/germany/#why-choose-azure-germany.
- Username and Password – enter credentials for connection to the organization. Use any of the following formats: email@example.com or firstname.lastname@example.org.
- Make sure the Grant impersonation to this user option is selected. This will allow the service to archive mail from other users’ mailboxes.
You may have impersonation granted manually, for example, via PowerShell (see Permissions section). However, if impersonation was not granted at all, Veeam Backup for Microsoft Office 365 will issue an error message when checking organization parameters, and mailbox processing will not be possible.
At the next step, Veeam will verify the connection settings you have provided, including connection to Exchange Web Services (EWS) and PowerShell, as well as the necessary roles assignment for the specified account.
A warning can appear in case the specified user account was not assigned the Application Impersonation role in advance, prior to running the wizard, and then Veeam will try to perform this role assignment. If parameter check returns Success after re-run, you can proceed with finishing the wizard; if it returns Failure, you may need to exit the wizard and check the required permissions. Contact your Exchange Online administrator, if necessary.
If impersonation was granted manually using PowerShell with some accounts filtered out ("partial impersonation"), then you will see a corresponding message. If then you decide to fully grant impersonation, you can re-run parameters check after granting.
Added Office 365 organization will be displayed under the Organizations node in the navigation pane of the Organizations view, its icon having a cloud in gray and red:
