Common Microsoft 365 Setup Issues DM1 Fixes
Most Microsoft 365 problems DM1 finds at new client onboarding aren't bugs — they're configuration gaps left by a previous IT provider. Here are the eight we find most often, in plain English.
Book a Microsoft 365 Health CheckMost M365 Problems Are Configuration Problems — Not Microsoft Problems
When DM1 takes over IT support for a Perth business, the first thing we do is a Microsoft 365 health check — a systematic review of the tenant's configuration against current best practice. In nearly every case, we find issues that the previous provider either didn't know about or didn't fix. None of them require a support ticket to Microsoft. All of them are DM1 configuration work.
These eight issues are drawn from DM1's experience across more than a decade managing Microsoft 365 tenants for Perth SMBs. If your business has been on Microsoft 365 for more than 12 months without a configuration review, at least three of these are likely present in your tenant right now.
The 8 Most Common Microsoft 365 Setup Problems DM1 Finds
Each issue below includes what goes wrong, why it matters, and exactly what DM1 does to fix it.
No Multi-Factor Authentication Enforced
WHAT GOES WRONG
Staff access Microsoft 365 with a username and password only. One compromised password — from a phishing email, a data breach, or a weak choice — gives an attacker full access to business email, files and contacts from anywhere in the world. This is the most common and most dangerous finding DM1 makes.
WHAT DM1 DOES
DM1 enforces MFA for all user accounts using Microsoft Entra security defaults or Conditional Access policies. Staff are guided through setting up the Microsoft Authenticator app on their phone. Takes less than an hour to implement across a typical Perth SMB.
Email Authentication Records Missing or Incorrect (SPF, DKIM, DMARC)
WHAT GOES WRONG
Without correct SPF, DKIM and DMARC records in your domain's DNS, your emails go to spam, your domain can be spoofed by attackers, and you have no visibility into who's sending email on your behalf. DM1 finds at least one of these three records missing or misconfigured in the majority of new client tenants.
WHAT DM1 DOES
DM1 audits your DNS records using independent verification tools, configures SPF, DKIM and DMARC in your DNS zone, verifies email delivery through major providers, and moves DMARC to enforcement mode once SPF and DKIM are confirmed working.
Former Employee Accounts Still Active and Licenced
WHAT GOES WRONG
When a staff member leaves without a proper IT offboarding, their Microsoft 365 account often stays active. This means their email still receives messages, their OneDrive files remain accessible to anyone with their password, and your business is paying for a licence for an account no-one is managing.
WHAT DM1 DOES
DM1 audits every account in your tenant against your current staff list. Former employee accounts are identified, their data is retained and transferred to a nominated account, and the licence is removed. Done correctly, this typically takes 15–30 minutes per account.
Shared Mailboxes Incorrectly Assigned Paid Licences
WHAT GOES WRONG
Shared mailboxes — such as reception@, info@, accounts@ — do not require a paid Microsoft 365 licence in most configurations. DM1 regularly finds these accounts assigned Business Standard or Business Premium licences, costing Perth businesses A$22.44–$39.48/user/month + GST for accounts that should be free.
WHAT DM1 DOES
DM1 converts incorrectly licenced shared mailboxes to proper shared mailbox configuration in Exchange Online, removes the unnecessary licence, and confirms access is maintained for all staff who need it. The saving is immediate — applied to the next billing cycle.
No SharePoint Structure — Files Stored in Email or Locally
WHAT GOES WRONG
Without a proper SharePoint document library structure, businesses end up with files scattered across email attachments, individual OneDrive accounts, local desktop folders and USB drives. There's no central version control, no shared access, and no ability to find anything quickly.
WHAT DM1 DOES
DM1 designs and builds a SharePoint document library structure that reflects the business — departments, projects, client folders — and migrates existing files into it. Staff are shown how to access SharePoint from Outlook, Teams and the web. File chaos is one of the most impactful problems DM1 fixes.
Microsoft 365 Apps Not Activated or Running Old Versions
WHAT GOES WRONG
Staff on Business Standard or Premium licences are entitled to the full desktop Office apps — Word, Excel, PowerPoint, Outlook, OneNote. DM1 regularly finds businesses where staff are running old versions of Office that they purchased separately, or are using web apps only — unaware that full desktop apps are included.
WHAT DM1 DOES
DM1 checks the activation status of Microsoft 365 Apps on all staff devices, installs and activates the full desktop suite where it's missing, and removes old standalone Office installations that may conflict. Staff immediately gain access to the latest versions including Copilot Chat features.
No Conditional Access Policies — Any Device, Any Location
WHAT GOES WRONG
Without Conditional Access, your Microsoft 365 tenant can be accessed from any device, on any network, from any country in the world — including by a staff member's personal device that has never been reviewed by IT, or by an attacker using a compromised password from overseas.
WHAT DM1 DOES
DM1 implements a baseline set of Conditional Access policies appropriate for the business size and risk profile — typically requiring MFA, blocking legacy authentication protocols, and flagging risky sign-ins for review. For Business Premium clients, device compliance requirements are added via Intune.
Teams and SharePoint Configured Out of the Box — Never Customised
WHAT GOES WRONG
Microsoft 365's default Teams and SharePoint configuration is generic. Without customisation, businesses end up with Teams used only for chat, SharePoint files stored in default document libraries with no structure, and staff using personal cloud storage or email attachments for everything else.
WHAT DM1 DOES
DM1 designs a Teams channel structure and SharePoint library architecture that reflects how the business actually works — projects, departments, client files. Tabs for Planner, Lists and Forms are added where relevant. Staff are trained in the new structure in a single session.
What DM1 Finds in a Full Microsoft 365 Health Check
A DM1 health check goes beyond the eight issues above. It covers the complete Microsoft 365 configuration — security, identity, email, files, devices, and licences. Here's what's included:
Licence audit
Every account checked against your staff list. Unused licences, shared mailboxes with paid licences, and tier mismatches identified and corrected.
Email authentication
SPF, DKIM, DMARC and MX records verified. Sender reputation checked against major blacklists. DMARC moved to enforcement.
Security baseline
MFA, Conditional Access, Legacy Authentication blocking, admin account security, and sign-in risk policies reviewed and configured.
Device management
Intune enrolment status checked for Business Premium clients. Device compliance policies reviewed. Defender for Business activation confirmed.
SharePoint and Teams
Document library structure, sharing policies, guest access settings, and Teams channel configuration reviewed and improved.
External sharing
SharePoint and OneDrive external sharing policies checked against best practice. Oversharing identified and corrected.
