How to Dictate in Outlook (2026): Voice Typing, Email Compose, and System-Wide Options

You can dictate in Outlook, but only while a compose window is open

If your company runs on Microsoft 365, Outlook includes Dictate on the Message tab. Click in the body of a new mail or reply, start the mic, speak, and text appears where your cursor sits. That covers a lot of inbox work.

It does not cover everything. Dictate disappears once you leave compose. It will not type into Teams, Salesforce, or a Gmail tab your client insists on. And when you want a reply that reflects the whole thread without reading it aloud yourself, transcription alone is not enough.

This guide is for people searching how to dictate in Outlook, outlook dictate, outlook voice to text, or dictate emails in outlook in 2026: what Microsoft's button does, where speech to text outlook stops, and when UBIK Flow picks up the rest.

Quick answer

Built into Outlook (Microsoft 365): open compose or reply → click the body → Message → Dictate → speak → click the mic to stop.

Everywhere else on your desktop: UBIK Flow.

⌘⇧O / Ctrl+Shift+O: verbatim transcript at the cursor.
⌘⇧T / Ctrl+Shift+T: AI draft from what is on screen (the open thread, a PDF beside the inbox).

Mic check: Speech to text in your browser, free, no account.

Not the same thing: Copilot writes from a prompt. Read Aloud reads mail to you. Play My Emails plays your inbox on mobile. None of those are voice to text outlook in the compose field.

Dictate, Copilot, Read Aloud: pick the right tool

Outlook ships several voice-adjacent features. Mixing them up is the main reason people think dictation is broken.

Tool	You are trying to…	Input	Output
Dictate	Speak and see your words typed	Your voice	Text at cursor in compose
Copilot	Ask AI to draft or shorten a message	Written or spoken prompt	AI-generated text
Read Aloud	Hear an email read back	Existing message text	Audio
Play My Emails (mobile)	Listen to inbox while commuting	Inbox stream	Audio
Win+H (Windows)	Dictate in any app, including Outlook	Your voice	Text at cursor, no Office commands

Dictate sends audio to Microsoft's cloud speech service and needs internet on most tenants. Perpetual Office without Microsoft 365 often lacks the button entirely.

Turn on Dictate in a new message or reply

Before you start

Microsoft 365 account, signed into Outlook.
Microphone allowed for Outlook in OS privacy settings.
Dictation language matches the language you speak.

New email

New mail.
Click inside the message body (below the subject).
Message → Dictate.
Speak. Click the mic when finished.

Reply or forward

Open the thread → Reply or Reply all.
Click below the quoted text where your answer should start.
Message → Dictate, speak, stop.

Punctuation: say « comma », « period », « new line ». On Windows, Alt+' resumes dictation after you edit with the keyboard.

Subject line: click Subject first, then try Dictate. Support varies by build. If nothing happens, type the subject or put the cursor there and use UBIK Flow ⌘⇧O.

New Outlook, classic Outlook, web, and mobile

New Outlook (Windows): Dictate lives on Message while composing. If you toggled back to classic Outlook, the path is the same.

Outlook on the web: sign in with Microsoft 365 in Edge, Chrome, or Firefox. Compose window → Message → Dictate in the body.

Mac: Outlook for Microsoft 365, new or legacy UI → Message → Dictate. Grant mic access under System Settings → Privacy & Security → Microphone.

iPhone and Android: Outlook mobile does not always expose a compose Dictate button. Use the keyboard microphone in the body field, the same workaround as Gmail on mobile. Play My Emails is for listening, not typing.

When Outlook Dictate is enough (and when it is not)

Scenario	Outlook Dictate	Better option
Long reply, you know the wording	Yes	—
Quick « thanks, received »	Yes	—
Reply that must reference three earlier messages in the thread	Partial	⌘⇧T reads the visible thread
Message in Slack while Outlook stays open	No	⌘⇧O in Slack
CRM note from the email on screen	No	⌘⇧T in the CRM field
Confidential mail, IT blocks cloud speech	No	Ask IT, or on-device dictation via UBIK Flow

Outlook Dictate is strong for dictate emails in outlook when you are already in the compose window. It weakens the moment your cursor moves to another app or you need the screen, not just your voice, to shape the answer.

UBIK Flow for the rest of your email day

You do not need to uninstall Outlook Dictate. Most people use both.

Raw words: ⌘⇧O / Ctrl+Shift+O

Click the field (Outlook body, subject, Slack, browser form).
Hold the shortcut, speak, release.
Edit typos and send.

Use this when you know the sentence and Outlook's mic is greyed out, or you are outside Outlook.

Thread-aware draft: ⌘⇧T / Ctrl+Shift+T

Leave the email thread visible.
Click where the reply should go.
Press the shortcut and say: « Decline politely but offer Thursday » or « Summarize the ask and confirm budget. »
Review before sending.

Use this when the reply depends on what is on screen, not only on what you can say from memory.

	Outlook Dictate	UBIK Flow ⌘⇧O	UBIK Flow ⌘⇧T
Needs compose window open	Yes	No	No
Verbatim transcript	Yes	Yes	No
Uses visible thread	No	No	Yes
Works in non-Outlook apps	No	Yes	Yes

Test your mic before a client-facing session.

Three inbox workflows people actually dictate

1. The vendor negotiation reply. Twelve messages deep. You could read the thread aloud into Dictate, or open reply, press ⌘⇧T, and ask for a short counter-offer based on what is visible. Dictate wins if you already scripted the answer; UBIK wins if the thread is doing the thinking.

2. The Friday recap. Reply all to an internal thread. Outlook Dictate for three plain paragraphs. No need for another tool.

3. The handoff to ticketing. Mail open on the left, Jira on the right. ⌘⇧T in the ticket description: « Turn the request in the email into bullet acceptance criteria. » Dictate never sees the Jira field.

Troubleshooting by symptom

Symptom	Likely cause	Fix
Dictate greyed out	Not on Microsoft 365 or not signed in	Sign in, confirm license
Outlook dictate button missing	Old build or admin disabled cloud speech	Update Outlook, try web, ask IT
Outlook dictate not working mid-sentence	Network drop	Reconnect, restart Dictate
Wrong language output	Dictation language mismatch	Change language in Dictate menu
Text goes to wrong place	Cursor in header or search	Click body first
Works in web, not desktop	Policy or add-in conflict	Compare tenants, reset Outlook
Copilot works, Dictate does not	Separate admin toggle	IT enables speech input

Outlook vs Gmail for voice typing on desktop

	Outlook (M365)	Gmail
Native dictation in compose	Yes (Message → Dictate)	No
AI draft from prompt	Copilot	Gemini « Help me write »
Best UBIK mode for thread replies	⌘⇧T when Dictate is not enough	⌘⇧T (no native option)
Mobile	Keyboard mic	Keyboard mic

Google users: see dictate in Gmail. Microsoft shops: start with Outlook Dictate, add UBIK Flow when you leave the compose window or need screen context.

What UBIK Flow does not do

Does not manage folders, rules, or calendar scheduling.
Does not send mail without your review.
Does not require Microsoft 365 for dictation outside Outlook.
Does not sync with Exchange policies beyond what your browser session can see.

Gmail: no desktop dictation button.
Word: Dictate inside documents only.
Slack: no native voice typing.
Dictate on Windows: Win+H everywhere, different from Office Dictate.
Dictate on Mac: system dictation vs in-app tools.
