Microsoft 365 vs Office 2024: Apps, Updates, Offline Access and Copilot Compared

The core apps and what each one does​

• Word creates and edits documents.
• Excel handles spreadsheets, calculations and data analysis. PivotTables, charts and conditional formatting are its main analysis tools.
• PowerPoint builds presentations.
• Outlook manages email, contacts and calendars.
• OneNote is a digital notebook for class notes, meeting records and loose ideas.
• Access builds small relational databases with tables, forms, queries and reports. It isn't in every edition. Microsoft's Office 2024 FAQ lists it for Office LTSC 2024 as Windows-only, and its subscription comparison says PC users get Access.
• Teams covers chat, meetings and shared channels. Don't assume it comes with every Office purchase.

The apps run on desktops, in browsers and on phones. Some features work offline, but anything cloud-based needs a connection.

Which package includes which apps​

A product's name doesn't tell you its app list, so check the specifics. Microsoft's Office 2024 FAQ describes two consumer editions:

• Office Home 2024 is a one-time purchase for one PC or Mac. It includes classic Word, Excel, PowerPoint and OneNote, and is aimed at home or school use.
• Office Home & Business 2024 adds Outlook to that set. It is aimed at home or work use.
• Office LTSC 2024 is the on-premises edition for commercial and government customers. It includes Word, Excel, PowerPoint, Outlook, OneNote and Access (Windows only). Publisher is not included, and Microsoft says Publisher is being retired in 2026.
• Microsoft 365 subscriptions cover Personal, Family, Premium, Pro and Basic for home use. Business, enterprise, education and nonprofit plans are separate.

Microsoft's own comparison page also says you can buy standalone Word, Excel or PowerPoint, and Visio or Project (PC only), if you only need one app.

Subscription or one-time purchase​

Microsoft's support documents describe the trade-off this way:

• Updates. Microsoft says Office 2024 has security updates but no new features, and that upgrading to the next major release means paying full price. Third-party coverage from 4sysops says the same: Office 2024 users receive only security updates and bug fixes, with no new features added after purchase. Microsoft 365 apps keep getting feature updates.
• Devices. Office 2024 licenses permit installation on only one computer. Microsoft 365 plans let you sign in on five devices at once. Family, Premium and Pro plans can also be shared with up to five other people.
• Cloud storage. Microsoft says Office 2024 includes none of the subscription services. Microsoft 365 Personal includes 1 TB of storage. Microsoft has also announced larger pooled OneDrive allowances. From October 8, 2026, new Family and Premium subscribers get 2 TB pooled, and Pro subscribers get 5 TB. Existing Family and Premium subscribers move to 2 TB at renewal from May 2, 2027.
• Support lifecycle. Office LTSC 2024 goes out of support on October 9, 2029. The consumer Office 2024 falls under the Modern Lifecycle Policy.
• Install technology. Both Office 2024 and LTSC 2024 install through Click-to-Run rather than MSI on Windows.
• VBA. Both Office 2024 and LTSC 2024 still support Visual Basic for Applications.

For Windows admins, one detail stands out. Microsoft says Office LTSC 2024 security and quality updates can be hosted on-premises for disconnected networks. Consumer Office 2024 is not meant for fully disconnected use.

"Offline" has limits in both models​

The idea that a one-time purchase never needs the internet is wrong. Microsoft says Office 2024 needs internet access to activate and to reactivate periodically. A change to your device's components can also trigger reactivation. Office 2024 apps may enter reduced functionality mode if device components change without reactivation.

Microsoft 365 works offline after installation and activation. If it doesn't connect at least once a month, it can drop into reduced functionality mode with an unlicensed-product error. Reconnecting and signing in fixes that. Office 2024 needs periodic connections for reactivation checks, and Microsoft 365 needs them to maintain subscription status.

Files don't have to live in the cloud under either model. You can save locally, or sync OneDrive files for offline access.

Copilot is not one feature​

"Copilot is included" is an incomplete claim. Microsoft's support pages say what you get depends on the license, the account you're signed in with and, for work accounts, organizational settings.

• Personal plans. Microsoft says AI features in Word, Excel, PowerPoint and Outlook are only available to the subscription owner. They are not shared with Family or Premium members. Microsoft also says age limits apply, which vary by region, and AI features are disabled for users under those ages.
• Work and school accounts. Whether a Copilot add-on license is assigned changes what you can do. Without one, Copilot Chat in Outlook can answer questions about your inbox, calendar and meetings, though with limited data. With an add-on license it can draw on chats and enterprise data too. In Excel, an add-on license also unlocks Agent Mode for multi-step tasks.
• Excel requirements. Microsoft says Copilot in Excel needs AutoSave on, which means the file must be saved to OneDrive.
• Office 2024. Third-party buying guides consistently say it lacks Copilot. One example: Microsoft Office 2024 does not include Microsoft Copilot features as part of the standalone license. Read that as a product-positioning claim from retailers and publishers. The practical point is that Copilot comes through subscription plans.

If the Copilot button is missing​

Microsoft's troubleshooting page, last updated July 2026, says first to look in the lower-right corner of your document. Copilot now opens from a single "Copilot Dynamic Action Button" there, so the button may have moved rather than disappeared. If it's really missing, work through these steps on Windows:

1. Install the latest Office build.
2. Go to File > Account and select Update License. Then close and restart all Microsoft 365 apps.
3. If you're a business user, check your update channel under File > Account, in the Product Information section. Microsoft says Copilot features aren't available on Semi-Annual Enterprise Channel. You need Current Channel or Monthly Enterprise Channel, and your help desk handles the switch.
4. Go to File > Account, then Account Privacy > Manage Settings. Confirm that "Experiences that analyze your content" and "All connected experiences" are both turned on. Managed organizations control these settings through IT.

On a Mac, Microsoft's steps use the app menu: About > More Info > Refresh License. Privacy settings are under Word > Preferences > Privacy. In a browser, a blocked third-party cookie can stop Copilot from validating your license, so Microsoft suggests refreshing and allowing them.

A quick decision guide​

Alternatives, briefly​

The Analytics Insight overview that prompted this guide lists Google Workspace, LibreOffice, Apple iWork and WPS Office as the usual alternatives. The first is browser-based, the second is free and open source, the third is Apple-only, and WPS Office adds PDF tools. They are fine for many jobs. Your budget, your devices, and how often you swap files with Office users should decide.

Bottom line​

Pick the product by apps, devices, update model and Copilot eligibility, not by the "Office" label. Microsoft's pricing and plan contents change, so check the current comparison page before you buy.
