Microsoft 365 is probably the most important software subscription your business pays for. It runs your email, your calendars, your documents and, increasingly, your meetings and phone calls. Yet in nearly every Microsoft 365 environment we review, the same story repeats: the business is paying for a powerful platform and using a small fraction of it.
Sometimes the missing pieces are productivity features nobody had time to set up. More often, and more importantly, they’re security settings that were never turned on. The result is a business that pays for enterprise-grade tools but gets small-business protection.
Here’s where we typically find the biggest opportunities, organized into three areas: security, licensing and productivity.
Part 1: Security settings worth checking today
Microsoft 365 is a frequent target for attackers because one compromised account can expose email, files and sometimes finances. The platform includes strong protections, but many of them are optional or depend on your license.
Turn on multi-factor authentication for everyone
If you do nothing else, do this. Multi-factor authentication (MFA) blocks the vast majority of password-based attacks. Microsoft offers free “security defaults” that require MFA for all users, and businesses with the right licenses can use more flexible conditional access policies instead. What matters most is that every account is covered, especially administrators.
Block legacy sign-in methods
Older email protocols don’t support MFA, which gives attackers a way around it. Unless you have a specific need for them, legacy authentication should be blocked.
Separate administrator accounts
The account you use to read email every day shouldn’t be a global administrator. We set up separate, protected admin accounts that are used only when administrative work needs to be done.
Watch for suspicious forwarding rules
A common trick after an account is compromised is to create a rule that quietly forwards email to an outside address, or hides replies from the real user. Blocking automatic external forwarding and reviewing mailbox rules closes a surprisingly common gap.
Review external sharing
SharePoint and OneDrive make it easy to share files, sometimes too easy. Check whether “anyone with the link” sharing is allowed, and whether it’s appropriate for your business. Many firms choose to limit sharing to specific people and set expiration dates on external links.
Part 2: Licensing, the quiet budget leak
Microsoft 365 licensing is genuinely confusing, and it changes often. That confusion tends to cost money in two directions.
Paying for licenses nobody uses. Former employees who were never removed, shared mailboxes that were given a full license when they didn’t need one, and duplicate subscriptions bought by different departments are all common. A simple license audit often pays for itself immediately.
Missing out on what you could have. On the other hand, some businesses are on lower-tier plans and paying separately for tools that a higher tier would include. For many small and mid-sized businesses, Microsoft 365 Business Premium is worth a close look. Alongside the familiar Office apps, it includes advanced security features such as Microsoft Defender for Business, Intune for managing and securing devices, and conditional access. For businesses that would otherwise buy separate security or device management tools, it can simplify both the stack and the bill.
The right mix depends on your team. Front-line staff who only need email and Teams might use a lighter license, while office staff and managers need the full suite. We review licensing with every client at least once a year and make sure the mix still matches how people actually work.
Part 3: Productivity features you’re already paying for
Once security and licensing are in good shape, there’s real value to unlock in how your team works day to day.
Move off the old file server
Many businesses still store shared files on an aging on-site server or a mapped drive that only works in the office. SharePoint and Teams can replace that with secure, searchable file storage that works from anywhere, with version history, so an overwritten file can be recovered in seconds. A well-planned migration keeps your familiar folder structure and permissions, so the change feels natural.
Use Teams as more than a chat app
Teams works best when it becomes the hub for how departments and projects communicate: channels organized around teams or clients, files attached where the conversation happens, and shared calendars. With Teams Phone, it can even replace a traditional phone system, letting staff make and receive business calls from their laptop or mobile.
Standardize onboarding and offboarding
With Intune and good group design, a new employee’s laptop can arrive preconfigured with the right apps, settings and security policies. When someone leaves, access can be removed in minutes and company data wiped from their devices, without touching their personal information.
Take advantage of built-in automation
Tools like Microsoft Forms, Bookings, Planner and Power Automate can replace paper forms, back-and-forth scheduling emails and spreadsheets tracked by hand. These don’t need to be complicated projects. Automating one repetitive process per quarter adds up quickly.
Don’t forget backup
One of the most important points we make with clients is that Microsoft keeps your data available, but it isn’t a traditional backup service. Deleted items and older file versions are retained only for limited periods, and if ransomware encrypts files on a synced laptop, those encrypted files can sync straight to OneDrive.
A dedicated Microsoft 365 backup keeps independent, point-in-time copies of your email, OneDrive, SharePoint and Teams data, so you can restore a single message or an entire site from any day in your retention window. It’s inexpensive and one of the easiest risks to eliminate. Microsoft 365 backup is included in our Business and Premium managed IT plans, and it’s available as an add-on to our Essentials plan or on its own, even if we don’t manage the rest of your IT.
A 10-minute Microsoft 365 health check
Here are some quick questions to put to whoever manages your tenant:
- Is MFA enforced for every user, including admins and shared accounts?
- Are legacy authentication protocols blocked?
- How many global administrators do we have, and do they use separate accounts?
- Is automatic forwarding to external addresses blocked?
- Are we paying for any licenses assigned to former employees or unused mailboxes?
- Would Business Premium replace tools we’re paying for separately?
- Is our email and file data backed up by a separate service?
- Are company laptops enrolled in device management?
If several of those don’t have a clear answer, there’s likely both savings and risk reduction waiting to be found.
How we help
Microsoft 365 administration is included in our Business and Premium managed IT plans. That includes migrations from on-site servers or other email platforms, security hardening, license optimization, and day-to-day management such as new users, shared mailboxes, Teams setup and permissions. Because we manage the platform every day for multiple businesses, we stay on top of Microsoft’s frequent changes so you don’t have to.
