How an expired card took a Victoria Park law firm's email offline for a morning
A five-user Victoria Park law firm lost all email one morning when their Microsoft 365 renewal was declined on an expired card. We found the cause fast and had everyone working again the same morning — but the outage cost the firm hours of billable time, a clear case for proactive IT that catches renewals before they bite.

Stopping sensitive data leaking to AI chatbots for a Perth building company

Shutting down an unauthorised TeamViewer access at a Joondalup building company
Staff were tricked into granting remote TeamViewer access in a fake support call. We identified and blocked the unauthorised access, worked directly with TeamViewer to lock the environment down the same day, and enforced a policy so only our team can connect — closing the door on a repeat.

Recovering a full NAS for an Osborne Park design firm — without new hardware
A design firm's NAS suddenly filled up and started disrupting day-to-day operations. We cleared accumulated deleted items to recover capacity immediately, then right-sized an over-long backup retention policy to prevent a repeat — with no hardware expansion.

Protecting a Perth firm's identities in the AI era with Conditional Access
A Perth CBD firm worried that AI-powered phishing made identity theft inevitable and their antivirus couldn't stop it. We rebuilt their security around identity — Microsoft Conditional Access, session-theft protection and passwordless sign-in — reaching 100% MFA coverage and cutting phishing success ~95% in four weeks.

Diagnosing Outlook 2016 sign-in failures against Microsoft 365 on a legacy RDS host
New Outlook 2016 profiles on a Windows Server 2012 R2 RDS host could no longer sign in to Exchange Online. We worked past TLS, Autodiscover and Conditional Access — reproducing the fault on our own tenant — to prove the cause was a modern-auth device-authentication step the legacy client can't meet, then scoped the permanent fix.

Stopping recurring Outlook freezes for a Perth design firm
An owner's Outlook kept freezing as shared and delegated mailboxes pushed her data file to the 50 GB limit. We freed ~15 GB and tuned the offline cache for a durable fix — each visit under 30 minutes.

My email just disappeared — does that mean I've been hacked?
A panicked 'hacked' email turned out to be Microsoft's Zero-Hour Auto Purge safely quarantining a phishing message after delivery. We confirmed no compromise in the sign-in logs and hardened the high-risk user.
Outcome
No compromise — verified in the logs. Hardened with Defender for Office 365 Plan 1 (safe links, safe attachments, time-of-click protection).

A SharePoint link from a genuine, trusted contact led a user through a convincing fake Microsoft login. We responded fast — signed the user out, reset the password, forced MFA re-registration and reviewed the sign-in logs.
Outcome
Contained the same morning — sign-in logs confirmed zero data accessed and no successful logins. Reinforced layered identity controls (Conditional Access, sign-in risk, token protection).
