Version history

Version2.3.4.1
Date23 Nov 2020
Fixed:The program would fail to perform an incremental backup of SharePoint folders that were renamed or moved between sites or libraries.
Fixed:The program would fail to back up SharePoint sites that have restricted guest users permissions assigned.
Fixed:The mechanism allowing users to use Office 365 server connections created by other users has been improved. The program now correctly handles the case when the connection is reconfigured by manually registering the CodeTwo application in Azure AD and using the certificate thumbprint credential.
Fixed:The information about the type of mailboxes included in a backup job will now be updated during the next backup cycle if there were any changes to the assignment of Exchange Online licenses to these mailboxes.
Fixed:If a user attempted to reconfigure an Office 365 server connection by using the Automatic registration option but did not save the changes made, the server connection would no longer work.
Fixed:The restore of SharePoint web pages that use web parts no longer worked after the Microsoft technology used in the program became deprecated.
Fixed:The restore of SharePoint surveys to an on-premises environment has been improved.
Fixed:The program would fail to back up a SharePoint site if any user added to that site could not be identified.
Version2.3.0.6
Date10 Aug 2020
New:

Support for OAuth 2.0 authorization:

  • the program uses OAuth 2.0 and the latest APIs to connect to and communicate with Exchange Online;
  • it is now necessary to register the program in Azure Active Directory of every Microsoft 365 (Office 365) tenant included in a backup or restore job. The program can perform the registration automatically (Microsoft 365 global admin account required), or you can choose to register the program yourself.
New:Backing up and restoring archive (in-place archive) mailboxes is now supported.
New:Mailboxes deleted from or disabled on a server are no longer automatically removed from a backup job. The program now notifies a user about such mailboxes and the user can decide whether to manually remove these mailboxes from the job.
New:Shared mailboxes no longer require licenses to be backed up.
New:Throttling is now handled more efficiently.
Fixed:The notification about the number of missing licenses that are needed to back up the selected SharePoint objects is now more precise.

Fixed:The program would fail to perform an incremental backup of or to restore SharePoint lists consisting of over 20,000 items due to throttling.
Fixed:The program failed to back up a SharePoint site if its URL has been changed on the server side.
Fixed:If a SharePoint list or library consisted of many empty folders, the program failed to back up items from other folders.

Fixed:Minor bugs fixed.
Version2.2.1.3
Date16 Sep 2019
New:Introduction of a new per-user licensing model where one user requires one license, regardless of whether you want to back up their mailbox or other resources they have access to.
