Completed a business IT and security audit across several Windows workstations. Bit-defender and remote management tools were deployed, previous malware damage was reviewed and the existing Microsoft 365 environment was documented for ongoing remediation.
Investigated Microsoft 365 email delivery problems across multiple accounts and computers. Exchange Online mail flow, tenant configuration and DNS records were reviewed, test messages were performed and additional email security records were added to DNS.
Performed data recovery from a faulty iMac and recovered more than 2TB of mixed files. The recovered data required significant sorting and recovery work because of the condition of the original storage.
Set up a new computer from scratch with Windows, OneDrive, Bitdefender, Microsoft 365 and Microsoft Edge. The Microsoft ecosystem was integrated and the old computer was removed from service once the replacement was ready.
Configured a local network share for business export files so authorized staff could access them across the LAN without interrupting the workstation used to generate the reports. The change provided a simpler interim workflow while a longer-term SharePoint solution was planned.
Regained access to Microsoft 365 administration and configured Admin Centre access on desktop and mobile devices. The tenant, licensing, workstation setup and security risks were reviewed, with remediation planned for shared systems and administrator access.
Corrected a OneDrive configuration where personal storage was conflicting with business SharePoint access. Organizational SharePoint synchronization was configured and a plan was developed to move business exports away from individual user storage into a shared SharePoint location.
Investigated a laptop that was stuck in Airplane Mode and could not restore Wi-Fi. Safe Mode and a USB Wi-Fi adapter were tested, and a wired Ethernet connection was provided as a reliable workaround while a Windows reinstall or deeper hardware diagnosis was considered.
Investigated a TV that was not powering on correctly and found a loose power connection. The TV was removed, connections were checked, the power issue was corrected and the unit was remounted before a remote support help-desk check confirmed normal operation.
Optimised a desktop computer by hardening the browser, removing bloatware and unnecessary applications, cleaning disk space and using WinDirStat to identify large files. NVMe SSD compatibility was also assessed and upgrade options were recommended.
