Datto SaaS Protection - M365 Backup Performance Degradation - Post-Graph Migration

Microsoft Graph API migration has been completed across all Datto SaaS Protection environments, including customers utilizing in-place archive configurations. No further migration activities are expected to impact backup operations. Some customers may continue to experience backup performance degradation while our engineering teams work to restore backup success rates to pre-migration levels. Multiple fixes and optimizations are being actively deployed across V2 and V3 environments, including improvements to Microsoft Graph API error handling and overall backup processing reliability. Teams continue to monitor the impact of each change as it is released. Current Backup Cadence: V2 environments: All Microsoft 365 services continue to back up three times per day. V3 environments: Exchange continues to back up three times per day. SharePoint, OneDrive, and Teams remain on a reduced cadence of one backup per day while optimization efforts continue to maintain high backup success rates and mitigate Microsoft service throttling. We do not currently have a fixed resolution date, as improvements are being delivered through ongoing remediation efforts rather than a single release. While performance is expected to continue improving, some customers may experience intermittent backup performance issues until all identified issues have been addressed. Based on current progress, we are cautiously optimistic that the remaining issues will be resolved over the coming days to weeks. We will continue providing updates as fixes are confirmed.
