Take Microsoft 365 Off Your Plate And Put It In Trusted Local Hands

Is the leadership still acting like the default Microsoft 365 admin every time Outlook breaks, Teams access fails, or a new employee needs to be set up?

Are you worried that old accounts, weak security settings, licensing sprawl, or missing cloud backup protections are creating risk you cannot easily see?

Do you want help from people who know your environment, not a rotating help desk that makes you start over every time?

That frustration is common in growing businesses, especially when Microsoft 365 has become essential to email, files, collaboration, and daily operations.

Open Tier Systems is a more human, responsive, and practical technology ally for small and mid-sized businesses that have outgrown patchwork support. With IT with H.E.A.R.T., a dedicated technical team, a client success manager, deep cybersecurity experience, and local support from Blue Bell across Eastern Pennsylvania, Open Tier helps businesses turn Microsoft 365 into a secure, dependable platform for smoother work and smarter growth.

What Is Microsoft 365 Support?

Microsoft 365 support is an ongoing service that manages and supports the Microsoft cloud tools your team depends on. That includes email, user accounts, Teams, OneDrive, SharePoint, licensing, access, and security settings, along with user support when problems come up.

Instead of leaving Microsoft 365 administration to an office manager, operations leader, or part-time internal IT contact, Open Tier Systems takes care of the work needed to keep the environment secure, organized, and useful as your business grows.

  • User onboarding, changes, and offboarding
  • Mailbox, Teams, OneDrive, and SharePoint support
  • Licensing reviews, renewals, and right-sizing
  • Security hardening for accounts, email, and sharing
  • Support for backup, access, and cloud collaboration tools

Who Is Microsoft 365 Support For?

This service is for small and mid-sized businesses in Eastern Pennsylvania that rely on Microsoft 365 and want it managed in a more secure, consistent, and business-friendly way. It is especially relevant for owners, executives, operations managers, and office managers who need dependable Microsoft 365 IT support without hiring a full internal team.

Open Tier Systems is a strong fit for businesses in construction, real estate, property management, architecture, engineering, home services, finance, legal, and other office-based or field-support industries that want a local partner who can support both cloud operations and broader business technology needs.

  • Businesses across Montgomery, Bucks, Chester, Delaware, and Philadelphia Counties
  • Teams with multiple employees relying on Outlook, Teams, OneDrive, and SharePoint
  • Companies that have outgrown informal or reactive Microsoft 365 administration
  • Organizations concerned about security gaps, licensing waste, or user access issues
  • Leaders who want one accountable partner for Microsoft 365 managed services and practical IT guidance

Why Should Your Business Invest In Microsoft 365 Support?

Investing in Microsoft 365 support helps your business get more value from the tools your team already uses. When a trusted partner manages email, Teams, OneDrive, SharePoint, accounts, security, and licensing, it helps you have a smoother workday, safer access, and more confident business growth.

Without the right support, Microsoft 365 can quietly create problems that slow your team down or add risk. Unused licenses, old accounts, weak security settings, poor file organization, missing backup protections, and unclear user access can all become barriers to growth. Open Tier Systems keeps your Microsoft 365 environment clean, secure, and aligned with how your business operates.

  • Help staff use Microsoft 365 apps more effectively
  • Reduce downtime caused by email, access, and collaboration issues
  • Right-size licensing to control unnecessary costs
  • Improve account, email, and file security
  • Support growth with a more organized and scalable Microsoft 365 environment

What you gain when a local Eastern Pennsylvania IT partner manages Microsoft 365 with security depth, dedicated support, and clear accountability.

A Cleaner, Safer Microsoft 365 Environment

  • Regular updates about support issues, changes, and recommendations

Frequently Asked Questions About Our Microsoft 365 Support Services

Answers to help you decide whether outsourced Microsoft 365 support is the right next step for your business.

Microsoft’s support helps with the Microsoft 365 product itself, but it does not act like your day-to-day IT partner. Open Tier Systems supports your business, not just the platform. We manage licensing, security settings, user setup, offboarding, and the issues your staff runs into every day, while also learning your environment over time so support becomes faster, more consistent, and more practical.

Yes. In many cases, that is the best approach. Open Tier Systems can work with your current Microsoft 365 tenant and alongside an internal IT contact, office manager, or existing provider. We can take full responsibility for Microsoft 365 management or plug into the areas where your current team needs support, helping create cleaner roles, better coverage, and fewer gaps.

We handle the day-to-day Microsoft 365 issues that commonly slow teams down or create risk. That includes Outlook problems, mailbox changes, password resets, Teams access issues, OneDrive sync problems, SharePoint permissions, new user setup, offboarding, group and shared mailbox changes, licensing adjustments, security setting reviews, and troubleshooting around how users access Microsoft 365 apps and data.

We keep onboarding simple and structured. First, we meet with you to understand your business, users, and current Microsoft 365 setup. Then we perform a health, security, and licensing review of your tenant, document what we find, and agree on any cleanup or improvements. From there, we roll your users into our support process, explain how to get help, and begin managing the environment with a dedicated team that gets to know your business over time.

Small businesses should review Microsoft 365 licenses at least once or twice a year, and whenever employees join, leave, or change roles. Regular reviews identify unused seats, outdated plans, duplicate tools, and licensing costs that no longer match how your team operates. Open Tier Systems helps right-size your Microsoft 365 licensing so your business has the tools it needs without paying for unnecessary access or mismatched plans.

they help us work through problems without focusing on whose fault it is

I've been working with OpenTier since they launched and I feel so lucky to have their team in my corner. They have helped us wire and network three different offices, navigating the moves with ease. Their support team is always helpful in working through tech challenges and making sure everything is resolved. The best thing about them is that they help us work through problems without focusing on whose fault it is. They just fix things no matter what. That's hard to find.
