Don’t panic or start deleting random emails. First, check what’s using the most space: large attachments, deleted items, junk folders, old drafts and old sent emails are often the biggest culprits. You may need to archive older emails, store
documents offline, increase your mailbox storage, or review your current Microsoft 365 plan. If you’re unsure, Sistemz can help assess the best long-term solution for your business.

There are several possible causes, including a weak signal, router placement, interference from other devices, outdated equipment, or too many devices connected at once. Start by rebooting your router, checking for software updates, and moving closer to the router to see if the connection improves. If the problem persists, it may be time for a Wi-Fi health check to identify coverage issues, network bottlenecks, or equipment that needs upgrading. Sistemz can help optimise your network for a faster, more reliable connection.

A slow laptop is often caused by a lack of storage space, too many programs running in the background, outdated software, ageing hardware, or even hidden
malware. Start by checking your available storage, installing any pending updates, and closing unnecessary applications. If it’s still struggling, a health check can
identify what’s causing the slowdown and whether simple upgrades, such as additional memory or a faster SSD, could significantly improve performance. Sistemz can help get your device running smoothly again.
