Configured DKIM and DMARC records for a Google Workspace domain to improve email authentication, deliverability and protection against spoofing. DKIM signing was enabled and DMARC was placed in monitoring mode so mail flow could be observed safely before stronger enforcement.
Set up a new PC, transferred browser bookmarks and configured email. LibreOffice, 7-Zip and antivirus software were installed, and a Canon printer was configured despite Windows 11 driver compatibility issues.
Investigated Microsoft application lockouts caused by account and two-factor authentication problems. The issue could not be resolved remotely, but an onsite session corrected the account and recovery-email configuration and restored Microsoft 365 applications on the affected computers.
Backed up email, contacts and calendar data to PST before a planned Exchange migration. The impact on LEAP was reviewed with the software provider, Microsoft 365 provisioning and administrator access were coordinated, and phone and Outlook configuration were planned for the migration.
Set up a new Windows PC and worked around compatibility problems between the new Outlook and LEAP by installing classic Outlook. Google Workspace and additional email accounts were configured, while Bit-defender was installed across the computer and mobile devices.
Set up a replacement PC after storm-related data loss and recovered most available files from OneDrive. Microsoft 365, email, printer and Bitdefender were configured across computers and mobile devices, with operating system updates completed and parental-control setup.
Investigated intermittent email problems and adjusted Windows so classic Outlook remained the default mail client. A Mac DVD-burning issue and recording equipment were also checked, backup status was confirmed and a separate computer was assessed for a possible RAM upgrade.
Removed multiple competing antivirus products, restored Microsoft Office login and updates and cleaned up Outlook. Malwarebytes was updated and email was confirmed to be working correctly.
Cleaned malware from two laptops, removed unnecessary Norton and McAfee components and installed replacement endpoint protection. A Wi-Fi printer was configured, email issues were corrected and replacement of the older laptop was recommended because of long-term software damage.
Set up a new laptop and monitor, transferred data from the old PC and configured Microsoft 365, accounting software, two wireless printers and IMAP email. Dual-monitor support was enabled and internet instability was documented for follow-up.
Checked that backups were completing correctly, reduced intrusive antivirus behavior and cleaned dust from the PC to improve cooling. Default applications and broken email links were also repaired.
