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.
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.
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.
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.
Your Microsoft 365 licenses are tracked, adjusted, and reviewed so you avoid wasted seats, renewal surprises, and mismatched plans.
From baseline settings to ongoing changes, we manage your tenant and security controls so Microsoft 365 stays organized and protected.
Mailboxes, accounts, and shared data are better protected by modern controls that reduce the risk of phishing, spam, and account compromise.
From password resets to Outlook and Teams issues, our help desk gives your users fast, consistent support that reduces disruption.
New hires get the right access from day one, and departing users are removed cleanly so accounts, mailboxes, and permissions do not linger.
Regular reviews verify backup coverage, tighten configuration, and keep Microsoft 365 aligned with your workflows as your business grows.
Over time, Microsoft 365 can become a mix of unused accounts, loose permissions, inconsistent sharing, and settings no one fully understands. Open Tier Systems cleans that up and keeps it that way, so your environment is easier to manage and safer to rely on.
Working with Open Tier Systems means you are not left to manage Microsoft 365 through generic advice or disconnected support tickets. You get a local technology partner that understands Microsoft 365, cybersecurity, and the wider IT environment your business depends on, so support is more practical, more personal, and easier to trust.
Microsoft 365 support should not leave your team guessing what was fixed, what still needs attention, or who to contact when something comes up. Open Tier Systems gives your business a dedicated technical team and client success manager, so communication stays clear, consistent, and tied to your actual environment.
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.
