Trusted Support for Business-Critical Technology

See why organizations rely on OSG for practical guidance, ongoing support, and clearer IT planning.

We completely outsourced our IT department to Outsource Solutions Group, Inc. They handle all the security and critical patching to our infrastructure as well as all help desk support. We also procure all our hardware needs through Outsource. OSG is extremely responsive to our needs, handles tickets with care and timeliness too. We appreciate everything they do for us and would recommend their services to any business looking for an IT provider you can trust

Vice President Of Commercial Operations, Pharmaceutical Company

We started with OSG a few years back when we had issues with our former IT company. They were professional and quick to serve us. Since that day we have loved the relationship that we have with all the staff at OSG. Their customer service is outstanding. I wish we would have switched to them sooner and I would HIGHLY recommend them!

Director of Operations, Fox Valley Non-profit

Outsource IT Group has taken the time to learn our business, serve as a trusted partner, and provide a level of expertise that allows us to effectively allocate human resources to other critical services. In addition to providing us with technical and hardware support, the strategic quarterly meetings have helped us to grow as an institution through the implementation of new technologies and processes. Newly instituted services include increasing internet speed and stability, the pending implementation of RFID, and a successful transition to the Microsoft Phone System for unified communication. We would highly recommend their services to any organization looking for innovation and creativity.

Executive Director, Local Public Library

We’ve had an outstanding experience with Attentus. Brandon P., our NetAdmin, is proactive, attentive, and truly invested in our success. He consistently checks in, anticipates needs, and ensures we’re supported at every level. What really stands out is that Brandon goes the extra mile to troubleshoot issues thoroughly and stays with them until they’re fully resolved. We never feel like tickets are just being closed — he makes sure the solution actually works for our team.
Sean is always friendly, approachable, and completely solution-oriented. He makes even frustrating I.T issues feel manageable and keeps things moving quickly.
Logan has been invaluable when it comes to more complex projects. He approaches challenges thoughtfully, finds clear and effective solutions, and is patient with questions — explaining things in a way that even less tech-savvy folks can understand.
Joel O., our vCIO, has been a steady leader overseeing our biggest challenges and the overall health of our systems.
The team is consistently responsive and helpful, and their customer service truly stands out. Choosing Attentus is one of the best decisions we’ve made — they give us confidence and peace of mind every day.
Highly recommend!

Microsoft 365 Services Built Around Daily Operations

Licensing, security, support, and planning

Microsoft 365 licensing can become difficult to control as users, devices, and roles change. OSG reviews your current subscriptions, user needs, and administrative requirements to help align licensing with actual business use.

This gives you a clearer view of monthly costs, reduces unnecessary complexity, and supports better IT budget planning. The goal is simple: the right tools for the right users, managed with practical oversight.

Email remains one of the most critical parts of daily operations. OSG supports Microsoft 365 email environments with mailbox setup, account changes, access support, migration planning, and issue resolution for users who depend on reliable communication.

Support is handled with the broader IT environment in mind, so email, identity, devices, and security settings work together instead of becoming separate problems for your team to manage.

Teams, SharePoint, and OneDrive can improve productivity when they are structured correctly. OSG helps organize collaboration tools around how your people share files, communicate, and manage access across departments or roles.

This service supports smoother adoption, cleaner permissions, and fewer avoidable user issues. Your staff gets better use from Microsoft 365 without creating unmanaged file sprawl or confusing workspaces.

Microsoft 365 security depends on more than turning on basic settings. OSG helps manage identity, access, user permissions, and security configurations that reduce exposure while keeping employees productive.

Security planning can include multi-factor authentication, account review, conditional access considerations, and ongoing monitoring alignment. The result is stronger protection without unnecessary friction for day-to-day work.

Cloud migrations require planning across users, data, devices, applications, and business timing. OSG maps the environment before making changes, then supports the transition to reduce avoidable disruption and keep operations moving.

Migration support can include Microsoft 365 setup, mailbox moves, file migration planning, user communication, post-migration troubleshooting, and documentation. You get a structured process, not guesswork.

Microsoft 365 needs ongoing care after setup. OSG provides user support, administrative management, maintenance, troubleshooting, and strategic guidance so your cloud environment keeps pace with operational needs.

Dedicated account and technical management help connect day-to-day tickets with longer-term planning. That means recurring issues can be addressed at the root, not just handled one at a time as they appear.
