Microsoft product names

Microsoft product names have specific capitalization, spacing, punctuation, and spelling. Small slips-powerpoint, One Drive, Office365-are common and easy to fix once you know the patterns.

The sections below give concise rules, ready-to-copy rewrites for work, school, and casual contexts, and plenty of before/after examples you can use right away.

Quick rules at a glance

Use the official product name exactly: capitalization, spacing, and punctuation matter. Treat product names as proper nouns (PowerPoint, OneDrive, Microsoft 365). When a product name modifies a noun, keep it capitalized (a PowerPoint presentation).

• Keep internal capitals: PowerPoint, OneNote, SharePoint.
• Match official spacing and punctuation: OneDrive, Outlook.com, Microsoft 365.
• Don't invent or remove hyphens and spaces: Office 365 → Microsoft 365; Xbox Series X.
• Short forms like "ppt" are fine in chat; use full names in work and school.

Core rule: capitalization and official forms

Microsoft publishes each product name as a proper noun. Copy the exact form-capital letters and spacing are part of the name.

Lowercasing or splitting names reads informal and can confuse readers or search tools. When meaning is unclear, add "Microsoft" before the product (Microsoft Office vs. an office).

• Wrong: powerpoint
• Right: PowerPoint
• Wrong: microsoft
• Right: Microsoft
• Wrong: sharepoint
• Right: SharePoint

Spacing and punctuation (OneDrive, Outlook.com, Microsoft 365)

Some names are one word, some include punctuation, and some pair a product with a number. Match Microsoft's published spacing and punctuation so readers find the right product.

• OneDrive is one word; don't write One Drive.
• Outlook.com includes a dot when referring to the web service.
• Keep the space in Microsoft 365 and Windows 10; don't run versions together.

• Wrong: One Drive
• Right: OneDrive
• Wrong: Outlook com
• Right: Outlook.com
• Wrong: Office365
• Right: Microsoft 365

Hyphenation, numbers, and model names

Microsoft rarely uses hyphens inside product names. Model and version names keep separate words and capitals as published.

Write series and version labels with the spaces and capitals Microsoft uses.

• No hyphen for Xbox Series X - write Xbox Series X.
• Write Surface Pro 8, Windows 11, and Office 2019 with spaces.
• Use official abbreviations (e.g., VS Code) but spell the full name in formal writing.

• Wrong: Office-365
• Right: Microsoft 365
• Wrong: xbox-series x
• Right: Xbox Series X
• Wrong: visualstudiocode
• Right: Visual Studio Code

Spelling and internal capitalization (PowerPoint, OneNote, SharePoint)

Many Microsoft names use internal capitals (camel case). Those capitals change how the name reads and how people search for it-keep them intact.

Use apostrophes for possessives of the full name: PowerPoint's template.

• PowerPoint, not powerpoint or power point.
• OneNote and SharePoint keep internal capitals; don't split or lowercase them.
• Apostrophes: PowerPoint's slide, OneDrive's sync client.

• Wrong: powerpoint template
• Right: PowerPoint template
• Wrong: one note
• Right: OneNote
• Wrong: share point
• Right: SharePoint

Try your own sentence

Test the whole sentence rather than a single phrase-context often clarifies the correct form. Copy a complete sentence into a checker or proofread it aloud to spot awkward uses.

Grammar: using product names as nouns and adjectives

Product names can function as nouns (Open PowerPoint) or modifiers (a PowerPoint presentation). Keep the product name capitalized even when it modifies a common noun.

Avoid inventing verbs from product names in formal writing. Informal verb forms (e.g., "teams me") are okay in chat but not in reports or external messages.

• Correct: I attached the PowerPoint presentation.
  Incorrect: I attached the powerpoint presentation.
• Correct: Upload your paper to OneDrive.
  Incorrect: upload your paper to onedrive.
• Use "Microsoft Teams" for the app; use "teams" lowercase only when referring to groups of people.

• Rewrite:
  Wrong: i attached the powerpoint to the email.
  Rewrite: I attached the PowerPoint to the email.
• Rewrite:
  Wrong: turn in your onenote by friday.
  Rewrite: Please submit your OneNote notebook by Friday.
• Rewrite:
  Wrong: download microsoft teams and join.
  Rewrite: Download Microsoft Teams and join the meeting.

Memory tricks, similar-brand pitfalls, and when to relax the rules

Simple mnemonics help: if you see two small words that form the name, capitalize both (Power + Point → PowerPoint). When unsure, copy the exact form from an authoritative source.

Different brands use different patterns: Google Docs, Gmail, and iPhone follow their own rules-don't assume one pattern fits all.

• Mnemonic: "Internal capitals stay internal" - PowerPoint, OneDrive, OneNote, SharePoint.
• Compare brands: google docs → Google Docs; iphone → iPhone; gmail → Gmail.
• When to relax: informal chat can use "ppt," "teams," or lowercase shorthand; emails, essays, and published content should use the official form.

• Wrong: google docs
• Right: Google Docs
• Wrong: iphone
• Right: iPhone
• Wrong: gmail inbox
• Right: Gmail inbox

FAQ

Should I write PowerPoint or powerpoint?

Write PowerPoint with internal capitals. Lowercase "powerpoint" is informal and incorrect in work or school settings.

Is OneDrive one word or two?

OneDrive is one word with an internal capital D. Don't split it into One Drive in formal writing or instructions.

Do I need to add ® or ™ after Microsoft product names?

For everyday emails and documents you can omit trademark symbols. Add them only if your legal or brand guidelines require it.

Can I say "sent the ppt" in a work email?

Avoid "ppt" in formal emails and external communications. Use "PowerPoint" for clarity; "ppt" is acceptable in casual chat among colleagues.

How do I fix a sentence that uses "office" incorrectly?

Decide whether you mean the Microsoft product or a location. Use "Microsoft Office" for the software suite and "office" lowercase for a place: "Open the file in Microsoft Office" vs. "I'll be in the office today."

Quick check before you send

If you're unsure, copy the full sentence into a spell-checker or search the product name in a trusted source and match the exact form. A quick verification prevents small but visible errors in emails, proposals, and assignments.
