Common IT Issues Small Business Perth -- Perth IT Care

03 July 2026·3 min min read· IT Support

It's 9.15am on a Tuesday. Someone's email won't send, the printer has vanished from the network, and there's a client meeting in 45 minutes. Sound familiar? If you run a small business in Perth, it probably does. These aren't random disasters -- they're the same common IT issues small business Perth operators deal with week after week, usually at the worst possible moment.

Most of them have a fix you can try yourself in under five minutes. A few of them don't -- and knowing which is which will save you from making things worse. This post covers the ten problems we see most often, what to try first, and when to stop tinkering and call someone.

If you're finding that these problems are becoming a regular pattern rather than the occasional bad morning, it's worth reading about the benefits of IT support for small business -- because recurring IT problems aren't bad luck, they're a symptom of something that needs addressing properly.

1. Email Stuck in Outbox or Not Sending

The most common cause in Microsoft 365 is an authentication prompt that's been dismissed or ignored. Outlook loses its connection to the server, sits there quietly failing to send, and nobody notices until someone follows up on an email that was never received.

Try this first: Close and reopen Outlook. If you see a password prompt, enter your credentials. Check your internet connection is actually working by loading a webpage. If the email is stuck in the Outbox, try right-clicking it and moving it to Drafts, then resend.

Call your IT person if: You're entering your password and it keeps failing, other staff are having the same issue at the same time, or you're getting bounce-back errors with error codes (550, 421, and similar). These point to server-side issues, mailbox quota problems, or an account that's been flagged -- none of which you can fix from Outlook.

2. Forgotten Password or Locked Account

This one stresses people out more than it should. A locked Microsoft 365 account isn't a disaster -- it's a Tuesday.

Try this first: Go to aka.ms/sspr (Microsoft's self-service password reset). If your organisation has it enabled, you can reset your own password without involving anyone else. Takes about two minutes.

Call your IT person if: Self-service reset isn't working, your account keeps locking itself out repeatedly (this can indicate someone else is trying to log in with your credentials), or you've lost access to your authenticator app as well. Repeated lockouts warrant a proper look at your account activity.

While you're at it, this is a good prompt to sort out your password habits properly. A password manager for small business removes most of this problem entirely.

3. Printer Not Found on the Network

Network printers are one of those things that work perfectly for months and then inexplicably disappear. Usually it's one of three things: the printer has been assigned a new IP address by the router, Windows has decided to disable network discovery, or the driver has thrown a tantrum.

Try this first: Turn the printer off, wait 30 seconds, turn it back on. Then restart the computer. Go to Settings > Bluetooth & devices > Printers & scanners, remove the printer, and try to add it again. If your printer has a touchscreen, check the network settings -- it'll show the IP address it's been assigned.

Call your IT person if: The printer shows an IP address but still won't connect, the problem comes back every few days, or you have multiple users affected across different computers. A proper fix usually involves giving the printer a static IP address so this stops happening.

4. Slow Internet During Business Hours

Perth businesses on FTTN NBN connections often experience genuine congestion during business hours -- roughly 9am to 5pm on weekdays -- particularly in higher-density commercial areas. This isn't your equipment failing. It's a capacity issue on the network between your premises and the NBN node.

Try this first: Run a speed test at fast.com or speedtest.net. Note the time and your result. If your speeds are significantly below what you're paying for, run the same test after hours to compare. Also check whether the slowness affects all devices or just one -- that narrows it down to either the network or a specific machine.

Call your IT person if: Speed tests confirm you're getting a fraction of your plan speed consistently during business hours, if one device is dramatically slower than others, or if the problem started after any changes were made to your network equipment.
