An organization once faced issues where some mailbox data was not included in their backup. The problem wasn’t the tool—it was the process. They were not checking filters, date ranges, or skipped items. After reviewing their method, they started using SysInfo Office 365 Backup Software more carefully—ensuring all folders were selected, avoiding unnecessary filters, and reviewing logs after backup. This improved their results and helped them achieve complete data backup without loss.
