Every second between an outage starting and users knowing about it is a second of mounting tickets, Slack messages, and phone calls your IT team needs to handle while also fixing the problem.
Why silence during an outage is expensive
When systems go down without warning, users assume the worst and act accordingly. They open tickets. They call the help desk. They message IT staff directly. They post in Slack channels. All of this happens simultaneously while your team is trying to diagnose and resolve the incident.
A single mass notification — "Email is down, we're on it, ETA 45 minutes" — stops most of that. Users have a status. They stop interrupting the response. Your help desk queue stays flat.
The notification needs to arrive in seconds, not minutes. And it cannot rely on the systems that are down.
The problem with email during outages
Email is the default channel for most IT communication. It's also the first to become unreliable during an incident.
If the mail server is the affected system, emails are queued or lost. If the issue is network-related, email delivery slows or stops. If your Microsoft 365 tenant is affected, email, Teams, and SharePoint may all be unavailable simultaneously.
Sending an outage notification by email is exactly as reliable as the system you're trying to tell people is broken.
Desktop alerts as out-of-band communication
A desktop alert works differently. It delivers over a channel independent of email servers and collaboration tools. The alert reaches the screen directly — locked, in standby, or active — without routing through any of the systems under incident.
When Microsoft 365 is down, Notifiier still gets through.
The outage notification workflow
- Incident confirmed — monitoring alert, user report, or direct detection.
- Open Notifiier. Takes seconds.
- Compose a short, direct message: what's affected, what you're doing, expected resolution.
- Send to all users, or the affected department.
- Get per-recipient confirmation in real time.
- Send an all-clear when service is restored.
The entire send flow — from opening Notifiier to the alert landing on every screen — takes under 60 seconds.
What if the alerting infrastructure itself is down?
This is the obvious question. The answer is architecture: Notifiier's delivery infrastructure runs independently of your internal email and collaboration stack. If your mail server is down, that doesn't affect Notifiier's ability to deliver desktop alerts.
For scenarios where connectivity is temporarily lost, the desktop client holds the alert in queue and delivers it the moment connectivity resumes. Users receive the notification as soon as they're back online.
Per-recipient confirmation
Knowing you sent the alert is not the same as knowing it was received. Notifiier returns delivery status per recipient. For a security incident, a mandatory all-staff notification, or any situation with compliance implications, you need to know specifically who received the message.
Forced acknowledgement takes this further: recipients must confirm they've seen the alert before they can dismiss it. Your incident record shows who acknowledged and when.
