Requirements
Please confirm you are running Veeam Backup for Microsoft Office 365 build 5.0.2.22 prior to installing this cumulative patch KB4187. You can check this under Help and Support > About in Veeam Backup for Microsoft Office 365 console. After upgrading, your build version will change to 5.0.2.42.
As a result of ongoing R&D effort and in response to customer feedback, cumulative patch KB4187 provides a set of bug fixes, the most significant of which are listed below:
Resolved Issues
General
- Under certain conditions a proxy may fail with the “Out of Memory” error during backup to an object storage repository.
Backup
- Microsoft Teams backup may fail with “Folder processing failed: Team Chat. Restriction contained too many elements” error.
- Backup of Team Chat messages created after October 2020 may fail with the “Failed to get TeamsMessagesData folder” error.
- Microsoft Teams backup fails with “Object reference not set to an instance of an object” error.
- OneDrive backup fails with “Object reference not set to an instance of an object” error if there’re any large OneNote files that are open and being edited during backup.
Restore
- In BaaS scenarios, exporting backup data to a local disk on the tenant side fails with the timeout error.
- Export operation in Veeam Explorer for Microsoft Exchange may fail with the “Connection to server was unexpectedly closed” error.
- For larger Office 365 organizations, some OneDrive accounts may not be displayed in the “Copy OneDrive” wizard
RESTful API
- SharePoint site title field is empty if such a site has been added to a backup job explicitly via REST API and the site title has not been explicitly specified.
- Removing a group with audit items via REST API doesn't work as expected but reports back response code 200.
- In BaaS scenarios with the modern app-only approach, obtaining a token for tenant authentication via REST API fails if a combination of capital and lower-case letters is used to specify the client_id parameter.
