Microsoft 365 support and management for Tulsa businesses
Your business runs on email, shared files, and people having the right access. NSN Management helps keep Microsoft 365 working, with everyday support for your team and ongoing care for your accounts, security, and backups.
Help with the Microsoft 365 problems that slow your team down
- Outlook and business email support. Help with sign-ins, mail delivery, shared mailboxes, and the email problems that interrupt your day.
- Employee account setup and removal. Set up new starters, change access when roles change, and secure accounts when someone leaves.
- Teams, SharePoint, and OneDrive support. Resolve file access, syncing, and sharing problems so your people can work together.
- Microsoft 365 licensing management. Review subscriptions, unused licenses, and the features your team actually needs.
- Account security and access controls. Strengthen sign-ins with MFA, review administrator access, and configure policies supported by your licenses.
- Microsoft 365 backup and recovery. Protect business mail and files with Datto SaaS Protection, backup checks, and tested restores.
Built for businesses with 10 or more employees that rely on Microsoft 365 every day. If your team still calls it Office 365, we can help with the business email, accounts, and files you depend on.
Small account problems can become business problems
- Former employees keep access to mail or shared files.
- Weak sign-in protection leaves business accounts exposed.
- Unused licenses stay on the bill while nobody reviews them.
- Your people lose time to the same email and file-sharing issues.

Connect Microsoft 365 to your ongoing IT support
Email and file problems often overlap with computers, networks, and security. Our Managed IT service in Tulsa brings Microsoft 365 administration together with help desk support, monitoring, patching, and technology planning.
Your proposal distinguishes ongoing management, Microsoft subscriptions, and any separately scoped migration or cleanup work. Pricing depends on your people, environment, and coverage.
Our main focus is ongoing, fully managed IT. Co-managed IT is a secondary offering with a specifically agreed scope.
Your people work. Microsoft 365 is handled.
Your team knows where to get help. Account changes follow a process, licenses get reviewed, and responsibility for security and backups is clear. You have a local team to talk through priorities with, instead of another administration task on your list.
NSN Management is Tulsa-owned and has supported local businesses since 2012. Our Microsoft 365 consulting and ongoing support connect the plan with the people who carry it out. See how we work and what clients say about our support.

Can you manage the Microsoft 365 account we already have?
Yes. NSN Management can review and manage your existing business Microsoft 365 environment, including its users, licenses, security settings, and support needs. You do not need to start with a new Microsoft 365 account to work with us.
Can we keep our email addresses and files when we switch IT providers?
Usually, yes. Changing who manages an existing Microsoft 365 environment generally does not require changing email addresses or moving files. NSN Management checks account ownership, administrator access, subscription arrangements, and your current provider's handover requirements before planning the transition.
Do you help with Outlook, Teams, SharePoint, and OneDrive?
Yes. NSN Management provides business support for Outlook and Exchange Online email, Teams collaboration, SharePoint, and OneDrive. That includes sign-in issues, shared mailboxes, file access, syncing, and sharing permissions, with administrator escalation when a problem needs deeper investigation.
What happens when an employee joins or leaves?
NSN Management handles account setup, licensing, and access changes using an agreed onboarding and offboarding process. When someone leaves, we secure their access and plan mailbox and file handover with your designated business contact, following your retention requirements.
Is Microsoft 365 support included in your Managed IT service?
Yes. Microsoft 365 administration is part of NSN Management's Managed IT service, alongside help desk support, monitoring, patching, security, and technology planning. Your proposal defines the covered services and distinguishes ongoing management from Microsoft subscriptions and any separately scoped projects.
How much does Microsoft 365 management cost?
NSN Management quotes Microsoft 365 management based on your user count, current setup, security and backup needs, and support scope. Microsoft subscriptions and migration or cleanup projects are identified in the proposal. The published Managed IT price range covers a broader service and is not a Microsoft 365-only price.
Can you help us migrate business email and files to Microsoft 365?
Yes. NSN Management helps plan Microsoft 365 migrations. We review your current email and file systems, data, permissions, licensing, and working hours before defining the migration scope, cutover plan, and support your people will need. Timing and project costs depend on that review.
Do you provide backup and recovery for Microsoft 365?
Yes. NSN Management uses Datto SaaS Protection for Microsoft 365 mail and files, with backup checks and tested restores. We document the accounts and data covered, retention, and recovery scope so you know what can be restored.
Can you work alongside our internal IT person?
Our primary offering is fully managed IT. Co-managed IT is a secondary service, with responsibilities and scope agreed in writing.
Do you provide Microsoft 365 support outside Tulsa?
Yes. NSN Management supports businesses across the Tulsa metro, including Broken Arrow, Jenks, Bixby, Sand Springs, Sapulpa, and Owasso. The service is built for organizations with 10 or more employees that need ongoing business IT support.
