Microsoft 365 has become the operational backbone for most Birmingham businesses, from logistics firms off the A38 to accountancy practices in the Jewellery Quarter. That dependency has also made the inbox the most reliable way for attackers to reach finance teams, customer data and supplier payments. The case for proper email security services in Birmingham now sits less with whether Microsoft’s built-in tools work and more with what they can’t see on their own.
Microsoft 365 runs most of the day-to-day for Birmingham businesses
Most Birmingham SMEs run Microsoft 365 for everything that matters in a working day, with Outlook for client correspondence, Teams for site coordination, SharePoint and OneDrive for shared documents, and Word and Excel for almost everything in between. Quotes go out through it. Purchase orders come in through it. Payroll instructions, supplier invoices and HR documents pass through the same handful of mailboxes.
That concentration is part of the appeal. One platform, one login, one bill. It’s also the reason a single compromised account can move sideways into shared sites, shared chats and shared payments before anyone notices. Microsoft 365 support in Birmingham typically covers user provisioning, licence management and day-to-day fixes. Proper email security sits on top, and it has to assume the platform itself is the target for businesses across Birmingham and the wider West Midlands.
Phishing, BEC and ransomware are still the dominant threats
According to the latest DSIT Cyber Security Breaches Survey, 43% of UK businesses, roughly 612,000, reported a cyber breach or attack in the last 12 months, and phishing was by far the most common type, hitting 38% of businesses directly. Medium and large firms fared worse, at 65% and 69%, respectively.
Verizon’s 2025 Data Breach Investigations Report puts a price on the most expensive variant. Business email compromise generated $6.3 billion in reported losses in 2024, with the median single complaint around $50,000. Verizon also flagged a quieter trend, with AI-assisted malicious emails roughly doubling (from around 5% to around 10%) over the past two years, which makes spear-phishing harder to spot at a glance.
For most Birmingham firms this lands as the same handful of threats. Spam clutter, ransomware payloads, spear-phishing aimed at named staff, business email compromise impersonating directors or suppliers, and account takeover. Each of those sits in scope for business email security in Birmingham, including the targeted attacks that look nothing like spam.
What Office 365 email security in Birmingham adds beyond the defaults
Microsoft’s standard protection (Exchange Online Protection, plus the URL and attachment scanning bundled into Microsoft Defender for Office 365) does a respectable job on volume threats. It catches most known-bad senders, blocks obvious malware attachments and flags the more obvious phishing patterns.
Where it tends to come unstuck is the targeted attack that doesn’t look like one. A spear-phishing email from a freshly registered domain mimicking your accountant. A wire-transfer request from a real, compromised supplier mailbox. A familiar device with an inbox rule forwarding everything to an attacker-controlled address.
Layered email security services add three things that matter here. API-based inbox defence that learns the normal pattern of who emails whom inside the business and flags deviations. Impersonation protection that catches lookalike domains and display-name spoofing. Account takeover detection that watches for the suspicious mailbox rules and login behaviour that follow a credential theft. Outbound encryption and email archiving sit on the same stack for regulatory work.
What local support adds to email security services in Birmingham
When a director rings finance asking why a £40,000 invoice has just been paid to a different sort code, the value of a remote-only support contract drops quickly. Local IT support in Birmingham means an engineer who can sit with the finance team, walk through the mailbox audit logs and reverse what’s reversible while the bank investigation runs.
For most West Midlands businesses, that’s the practical case for a local partner over a national helpdesk. MT Services’ email security service, built on Barracuda, runs alongside Microsoft 365 rather than competing with it. The team behind it has been supporting Midlands businesses from Tamworth since 1973. The work spans the initial review of what’s already in place, configuration of advanced filtering and impersonation rules, ongoing tuning, and training so staff recognise the kinds of message that still get through.
The Microsoft 365 price change is a natural moment to review
Microsoft confirmed in December 2025 that commercial Microsoft 365 prices will rise on 1 July 2026, with existing customers seeing the new rates at their next renewal after that date. The headline increases run from 5% on Microsoft 365 E5 to 33% on some Frontline tiers, and Business Standard is moving up by around 12%.
Some of that rise comes with bundled additions. Microsoft Defender for Office 365 Plan 1 will be included in Office 365 E3 and Microsoft 365 E3, and Business Basic and Standard pick up URL checks at time of click. Those are helpful inclusions. A feature inside a licence is still a tool with default settings, though. Someone has to configure it, monitor it and tune it against the threats a specific business is actually seeing.
A renewal is a natural moment to look at what you’re paying for and what it actually covers. Three things are worth a check. Whether licences are being paid for that staff don’t use. Whether the right Defender tier is active. Whether the layered email protection holds up against the spear-phishing and BEC patterns driving most modern losses. A short review now costs far less than a recovery later.

If your Birmingham business relies on Microsoft 365, the run-up to renewal is the right time to look at email protection alongside licence value. Get in touch with the team at MT Services for a straight conversation about what’s worth changing and what’s already doing the job.
Frequently Asked Questions
Does Microsoft 365 Business Premium already include email security?
Yes. Microsoft 365 Business Premium includes Microsoft Defender for Office 365 Plan 1, which adds Safe Links, Safe Attachments and impersonation protection on top of the standard Exchange Online Protection that comes with every 365 mailbox. Whether that’s enough depends on what’s being protected; Plan 1 handles volume threats well but doesn’t, by default, cover the targeted BEC and account takeover scenarios that drive most modern losses.
What's the difference between Microsoft Defender for Office 365 Plan 1 and Plan 2?
Plan 1 focuses on prevention, with Safe Links time-of-click checking, Safe Attachments sandboxing and impersonation protection. Plan 2 adds the post-incident side, including automated investigation and response, threat hunting, attack simulation training and Threat Explorer for digging into what got in and where it went. Plan 2 is included in Microsoft 365 E5; Plan 1 is included in Business Premium and (from 1 July 2026) Microsoft 365 E3.
What should a Birmingham business do if a Microsoft 365 account is compromised?
Immediate priorities are disabling the account, revoking active sign-in sessions, resetting the password, removing any inbox forwarding rules the attacker has set, and reviewing recent sign-in logs for the locations and devices involved. Any fraudulent payments need to go to the bank as quickly as possible, and any clients or suppliers who received messages from the compromised account should be told. A local IT partner who can act inside the tenant within minutes makes a measurable difference to how much of that gets contained.
