Activities: Office 365 files are being migrated from SharePoint to Azure. These files will be in read-only mode during the migration. Once all the files have been migrated to Azure and no more files are being written to SharePoint, the editing features will be re-enabled.
Potential User Impact: During the downtime, online editing for Word, PowerPoint, and Excel files will be disabled. Preview, downloading, or uploading a new version will remain available.
