Mission Operations
Microsoft 365 & Identity Management for Accounting Firms
Secure administration and clear ownership for the accounts, email, files, permissions, licenses, and collaboration services your employees use every day.
Business Infrastructure in the Cloud
Microsoft 365 is more than email. Identity connects the entire environment.
A single Microsoft account may control email, files, Teams, SharePoint, applications, remote access, password recovery, and the information an employee can reach. That makes identity both a productivity system and a security boundary.
Managed Microsoft 365 operations means controlling how accounts are created, protected, licensed, authorized, changed, recovered, and removed—while preserving the business’s ownership of its information as employees and responsibilities change.
The business should be able to answer:
- Who owns and administers the Microsoft 365 tenant?
- Does every person use an individually attributable account?
- Where is MFA required, and are exceptions known?
- Who can access sensitive mailboxes, files, and administrative tools?
- What happens to data and permissions when an employee leaves?
- Are licenses, applications, and security settings reviewed over time?
Identity Warning Signs
Small access shortcuts become lasting business risk.
Most identity problems begin as convenient exceptions: a shared password, an old account kept active, files saved in the wrong location, or broad access granted because there was no time to define the correct role.
Accounts are shared
Several people sign in as the same user, making activity difficult to attribute and access difficult to remove without disrupting everyone.
MFA has exceptions
Most users appear protected while older, shared, service, vendor, or administrative accounts remain accessible with a password alone.
Permissions accumulate
Employees retain mailbox, folder, group, application, and administrative access inherited from prior roles or temporary assignments.
Business files live in personal spaces
Important records remain in one employee’s OneDrive or mailbox instead of a business-owned location designed for shared responsibility.
Offboarding is improvised
Departures depend on memory, leaving uncertainty around sessions, forwarding, devices, shared data, groups, applications, and delegated access.
Licensing has no owner
The firm pays for unused subscriptions, assigns inconsistent capabilities, or changes licenses without considering security and retention effects.
Microsoft 365 & Identity Scope
What GreyFalcon manages
The objective is a Microsoft 365 environment that employees can use, administrators can explain, and the business continues to control as people, roles, devices, and information change.
Users, Groups & Licensing
Account creation, license assignment, groups, role alignment, shared resources, naming standards, and recurring administrative review.
MFA & Sign-In Protection
Multi-factor authentication, authentication-method management, secure recovery, exception review, and response to suspicious sign-ins.
Administrative Access
Restriction of privileged roles, separation of everyday and administrative use, emergency-access planning, and clearer accountability.
Email & Shared Mailboxes
Mailbox administration, aliases, shared mailboxes, delegated access, distribution, forwarding review, and practical ownership.
SharePoint, OneDrive & Teams
Business-owned file locations, sharing, site and team ownership, access structure, collaboration support, and lifecycle decisions.
Cloud Backup & Recovery
Specialized Microsoft 365 backup through Dropsuite for mailboxes, OneDrive, SharePoint, and Teams data, with monitored protection and recovery support.
The Identity Lifecycle
Access should follow the person’s role—not remain attached to their history.
Employees join, change responsibilities, work remotely, cover for colleagues, interact with vendors, and eventually leave. Each transition changes which information and systems they should be able to reach.
GreyFalcon coordinates those changes so access is available when needed, removed when no longer justified, and documented well enough that the next transition does not begin from guesswork.
Repeatable User Administration
Join, change, review, and depart.
User access is not a one-time setup task. It is an operating cycle tied to employment, role, business ownership, and security.
Join
Create an attributable account, assign the correct license and groups, configure MFA, and provide the resources required for the role.
Change & Review
Adjust access as responsibilities change and periodically identify unnecessary permissions, inactive accounts, and unclear ownership.
Depart
Block access, preserve business information, transfer responsibility, address forwarding and delegation, revoke sessions, and record completion.
Information That Belongs to the Business
Where a file lives determines who controls it later.
OneDrive is useful for an individual’s working files. SharePoint and Teams are generally better suited to records owned by a department, client team, process, or the business as a whole.
GreyFalcon helps establish practical locations and ownership so records do not become stranded when an employee leaves, a mailbox is removed, or a project changes hands.
File-governance questions
- Is this the employee’s work or the business’s record?
- Who needs access today?
- Who becomes responsible when a role changes?
- Is external sharing appropriate and reviewable?
- How will the information be retained and recovered?
- Can leadership identify the owner of the location?
For Accounting and Tax Firms
Identity controls must remain reliable under deadline pressure.
CPA firms, tax preparers, Enrolled Agents, bookkeeping firms, payroll providers, controllers, and internal accounting departments exchange sensitive information across email, shared files, portals, applications, offices, homes, and client locations.
Consistent accounts, MFA, permissions, file ownership, and offboarding reduce the chance that one stolen password, abandoned account, or misplaced folder becomes a larger security, compliance, or continuity problem.
Strong administration supports:
- individual accountability for access,
- protection of taxpayer and financial information,
- cyber-insurance control representations,
- WISP roles and access procedures,
- client and vendor security questions,
- repeatable onboarding and offboarding, and
- continued business ownership of records.
Licensing With Purpose
The least expensive license is not always the least expensive decision.
Microsoft 365 licensing affects security capabilities, device management, email, applications, retention, administration, and the support experience. Unused licenses waste money, but under-licensing can also create manual work and control gaps.
GreyFalcon helps align licensing with the employee’s role and the business’s operating requirements rather than treating every subscription as interchangeable.
A licensing review considers:
- the applications the employee actually uses,
- mailbox and collaboration requirements,
- security and identity capabilities,
- device and remote-work needs,
- shared resources and service accounts, and
- unused or duplicate subscriptions.
How an Engagement Begins
Start by identifying who has access to what.
1. Inventory
Review the tenant, domains, users, licenses, roles, groups, mailboxes, collaboration locations, applications, and known responsibility boundaries.
2. Validate
Compare accounts, MFA, permissions, ownership, sharing, administration, backup, and lifecycle practices with the business’s actual needs.
3. Prioritize
Correct immediate exposure, establish repeatable administration, document ownership, and plan the improvements that require broader change.
