How to Optimise Microsoft 365 for Remote Workers

Microsoft 365 has become the backbone of remote working for UK businesses. From Teams meetings and SharePoint collaboration to Outlook email and OneDrive file storage, the platform provides virtually everything a remote worker needs to stay productive. But there is a significant difference between simply having Microsoft 365 licences and having the platform properly optimised for remote work.

Many UK businesses rushed to deploy Microsoft 365 during the pandemic without taking the time to configure it properly. The result is a patchwork of suboptimal settings, underused features, and security gaps that cost productivity and create unnecessary risk. With hybrid and remote working now a permanent fixture of the UK business landscape, it is time to optimise your Microsoft 365 environment so that remote workers can perform at their best.

This guide covers the practical steps to optimise every aspect of Microsoft 365 for remote workers, from network performance and security settings to collaboration tools and user experience.

Optimising Network Performance for Remote Access

The single biggest factor affecting Microsoft 365 performance for remote workers is network connectivity. Unlike office-based staff who benefit from your business's dedicated internet connection and optimised network, remote workers rely on their home broadband, which varies enormously in quality across the United Kingdom.

Start by ensuring your Microsoft 365 tenant is configured to use optimal network routing. Microsoft operates a global network of Points of Presence (PoPs), and your traffic should be reaching the nearest one as directly as possible. In the UK, Microsoft has data centres in London and Cardiff, plus numerous edge locations. Enabling "direct connectivity" in your network configuration ensures remote workers connect to the nearest Microsoft endpoint rather than routing through your corporate network unnecessarily.

For organisations using VPN connections, this is particularly important. Traditional VPN configurations route all traffic — including Microsoft 365 traffic — through the corporate network and out via the office internet connection. This creates a bottleneck that degrades performance for remote workers. Implement split tunnelling for Microsoft 365 traffic, allowing it to travel directly from the remote worker's device to Microsoft's network while still routing sensitive corporate traffic through the VPN.

Configuring Teams for Optimal Remote Collaboration

Microsoft Teams is the hub of remote collaboration, but its default configuration is rarely optimal. Proper configuration ensures meetings run smoothly, channels stay organised, and remote workers can collaborate as effectively as if they were in the same office.

Meeting Quality Settings

Video call quality is the most visible performance indicator for remote workers. In the Teams admin centre, configure meeting policies to allow up to 1080p video quality for users with sufficient bandwidth, while setting lower defaults for users on constrained connections. Enable Network Quality of Service (QoS) markings so that routers and firewalls can prioritise Teams traffic. Configure bandwidth policies that adapt to available bandwidth rather than using fixed rates.

Channel Organisation

Teams channels can quickly become chaotic without governance. Establish a clear naming convention for teams and channels. Create a standard structure for each department or project, with dedicated channels for general discussion, announcements, and specific workstreams. Use private channels sparingly — they create information silos that can hinder collaboration. Pin important documents and links at the top of each channel so remote workers can find what they need quickly.

External Collaboration

Remote workers frequently need to collaborate with external clients, suppliers, and partners. Configure Teams external access and guest access policies to allow this while maintaining security. Enable guest access so external collaborators can join specific teams without needing a full Microsoft 365 licence. Set appropriate permissions so guests can access the files and channels they need without seeing anything they should not.

SharePoint and OneDrive Optimisation

For remote workers, file access is critical. SharePoint and OneDrive are the primary file storage and collaboration platforms in Microsoft 365, and their configuration directly affects how efficiently remote workers can access, edit, and share documents.

Enable the OneDrive sync client on all remote worker devices. This creates local copies of frequently accessed files, allowing staff to work offline and sync changes when connectivity is restored. Configure Known Folder Move (KFM) to automatically redirect Desktop, Documents, and Pictures folders to OneDrive, ensuring that important files are always backed up to the cloud and accessible from any device.

Structure your SharePoint sites logically. Each department or team should have a dedicated SharePoint site with a clear folder hierarchy. Avoid the common mistake of creating a single, monolithic SharePoint site with hundreds of nested folders — this makes navigation difficult and search unreliable. Instead, use multiple sites with clear purposes and use the SharePoint hub site feature to connect related sites together.

Configure versioning on all document libraries. This allows remote workers to recover previous versions of documents if changes need to be undone, and it provides an audit trail of who changed what and when. Set a reasonable version limit — 50 major versions is typically sufficient — to prevent storage from growing excessively.

Security Settings for Remote Workers

Remote working expands your attack surface significantly. Workers accessing corporate data from home networks, personal devices, and public Wi-Fi create security risks that must be addressed through proper Microsoft 365 configuration.

Conditional Access Policies

Conditional Access is one of the most powerful security features in Microsoft 365, and it is essential for remote working. Create policies that require multi-factor authentication for all external access, block sign-ins from countries where your business does not operate, require compliant devices for access to sensitive data, and limit session durations for unmanaged devices.

Data Loss Prevention

Configure Data Loss Prevention (DLP) policies to prevent sensitive information from being shared inappropriately. Create rules that detect and block the sharing of National Insurance numbers, credit card numbers, financial data, and other sensitive information via email, Teams, or SharePoint. DLP policies can warn users before they share sensitive data accidentally or block the action entirely for highly classified information.

Mobile Device Management

If remote workers access Microsoft 365 from mobile devices, implement Intune Mobile Device Management (MDM) or at minimum, Mobile Application Management (MAM). MAM allows you to protect corporate data within Microsoft 365 apps without managing the entire personal device, which is more acceptable to staff and avoids the privacy concerns associated with full MDM on personal phones.

Licence Optimisation for Remote Teams

Many UK businesses are paying for Microsoft 365 licences that do not match their actual needs. A remote workforce review often reveals opportunities to save money while actually improving the tools available to staff.

Audit your current licence assignments. Microsoft 365 Business Basic (£4.50 per user per month) provides web and mobile apps plus Teams, which is sufficient for many roles. Business Standard (£9.40 per user per month) adds desktop apps, which most remote workers need. Business Premium (£16.60 per user per month) includes advanced security features like Intune and Azure AD P1, which are essential for managing remote devices securely.

The most common mistake is assigning Business Premium to every user when many would be better served by Business Standard with selective security add-ons. Conversely, some businesses use Business Basic for all users, then wonder why staff cannot open documents offline — desktop apps are not included in that plan.
