Microsoft 365 support in Boise that stays manageable.
Castle IT is a Microsoft Cloud Solution Partner. We migrate email and files, harden the tenant, right-size licenses, and support day-to-day changes—so Microsoft 365 works for Boise and Treasure Valley businesses, not just on paper.
Office 365 and Microsoft 365 help for local teams.
If your staff live in Outlook, Teams, SharePoint, and OneDrive, you do not need a national helpdesk that never sees how a Treasure Valley office actually works. Castle IT sets up the tenant, keeps licenses honest, and answers when something breaks—email, sharing, MFA prompts, or a new hire on day one.
We support businesses in Boise, Eagle, Meridian, Nampa, Caldwell, and Star, and we can keep the same Microsoft 365 tenant healthy for teams that also work in Southern California. This page is for Microsoft 365. For full network, backup, and workstation coverage see managed IT services in Boise.
Setup & migration
Email, files, and collaboration tools with a planned cutover and rollback path—not a weekend cut-and-hope.
Teams, SharePoint, OneDrive
Configured for how your team actually works—not a default template left behind after the trial.
Licensing
Right plans per role, unused seats removed, billing simplified through one Microsoft partner.
Security hardening
MFA, Conditional Access, and Defender for Business tuned for your tenant instead of left on defaults.
Ongoing management
Users, licenses, troubleshooting, and changes on an agreed support plan with a person who picks up.
Azure when needed
Identity, virtual machines, and cloud infrastructure scoped to a real workload—not a catalog upsell.
Microsoft 365 or Google Workspace?
If your team already lives in Word, Excel, and Outlook, Microsoft 365 is usually the better fit. If everyone works only in the browser and already runs Google Workspace well, staying there can make sense. We help you choose based on apps, compliance needs, and support reality—not a product pitch.
What Microsoft 365 support in Boise actually includes
Most “Office 365 is down” tickets are not Microsoft being offline. They are a bad login, a license that expired, a sharing link that went to the wrong person, or MFA that nobody enrolled. We treat those as business problems: get the user working, then fix the tenant so it does not repeat.
Typical work: new-user onboarding, mailbox and alias changes, SharePoint permissions, Teams policies, laptop Outlook profiles, Defender alerts, backup of Exchange/OneDrive where the plan calls for it, and a quarterly license review so you are not paying for empty seats.

Jenny Fultz, CEO, Benita LLC
Castle IT has been our go-to solution for everything from website hosting and updates, Microsoft client support, system upgrades and additions and general IT services. Chris and his team have been consistently responsive and able to solve problems rapidly, helping our network of companies remain functional and effective. Our partner agencies are all in social services, so there isn’t a tech savvy person among us! It’s such a relief to have a resource like Castle IT to remove the headaches and hurdles that IT can often pose. I couldn’t recommend Castle IT more!

Why partner support matters
Default Microsoft 365 settings are rarely enough for a business that handles client data, remote staff, or regulated work. As a Cloud Solution Partner we configure the tenant, escalate through Microsoft when needed, and keep licensing and support in one place.
Common questions
Do you provide Microsoft 365 support in Boise?
Yes. Castle IT is local to the Treasure Valley. We set up, migrate, harden, and support Microsoft 365 for Boise-area businesses, with phone and remote help plus onsite when the job needs it.
What is included in Microsoft 365 Business Standard?
Typically desktop Office apps, Teams, SharePoint, OneDrive, and Exchange Online. We confirm current entitlements and match plans to each role.
How long does a migration take?
Most small Boise businesses under about 25 users finish in 1–3 days for email, accounts, core security settings, and handoff.
Can Castle manage our licenses?
Yes. As a Microsoft Cloud Solution Partner we can handle licensing, billing, and day-to-day management with regular right-sizing.
Is Microsoft 365 secure enough out of the box?
The platform is strong; default configuration often is not. We enable MFA, Conditional Access, and Defender for Business where appropriate.
Is this the same as Office 365 support?
Yes. Microsoft rebranded Office 365 to Microsoft 365. If you still search for Office 365 support in Boise, this is the same tenant, mail, and apps work.
