How to dictate in Outlook on Mac: Dictate, Apple Dictation, fixes

To dictate in Outlook on a Mac, open a new email or a reply and choose Message › Dictate (or press ⌥F1), wait for the mic to turn on, then talk. It needs a Microsoft 365 subscription and an internet connection; if you have neither, macOS's own Dictation works in the same message body for free.

Steps and requirements below come from Microsoft's Dictate your emails in Outlook and Apple's Dictation guide for Mac, checked November 2026.

#Option 1: Outlook's own Dictate

1. Open Outlook for Mac and make sure you're signed in to your Microsoft 365 account.
2. Click New Email, or Reply on a message. Dictate lives in the compose window, not the reading pane.
3. Click into the body of the message.
4. Choose Message › Dictate, or press ⌥F1.
5. Wait until the button shows it's listening, then speak.
6. Say punctuation where you want it ("comma", "period", "question mark", "new line"), or turn on Auto Punctuation in Dictate's settings if your language supports it.
7. Click Dictate again to stop.

The gear icon in the Dictate toolbar holds the useful settings: Spoken Language, Microphone, Auto Punctuation, and a filter that masks potentially sensitive phrases with asterisks. Microsoft lists 15 fully supported languages plus a longer set in preview, where accuracy and punctuation can be weaker.

In new Outlook for Windows and Outlook on the web the path is the same idea: select the message body, then Message › Dictate.

#Option 2: Apple Dictation in Outlook

macOS Dictation doesn't care which app you're in, so it types into the Outlook body like any other text field.

1. Open System Settings › Keyboard, scroll to Dictation and turn it on.
2. Check the Shortcut (pressing fn twice is the usual one) and the Microphone source.
3. Click into the Outlook message body and press the shortcut.
4. Talk, then press Esc or the shortcut again to stop.

On recent macOS versions Dictation adds commas, periods and question marks on its own, and it keeps going until you stop or stay silent for about 30 seconds. On macOS 14 and 15 the setting is in the same place.

#Which built-in to use

If you already pay for Microsoft 365 and only dictate inside Outlook, Dictate is fine. If you write in other apps too, Apple Dictation uses one habit everywhere.

#When the Dictate button is missing or does nothing

No Dictate button at all. Microsoft's answer is blunt: dictation is for Microsoft 365 subscribers. A one-time Office purchase, a work account without that feature, or a signed-out copy of Outlook won't show it. Also check you're in a compose window and not just reading a message.

Mac says Outlook can't use the mic. Open System Settings › Privacy & Security › Microphone and make sure Microsoft Outlook is switched on. If you denied it once, macOS won't ask again; flip the switch and restart Outlook.

"Another app is using your mic." Close Zoom, Teams, a browser tab with a call, or another dictation tool. Two tools listening at once is the most common reason for half-heard sentences.

It listens but types nothing. Look at the input level in System Settings › Sound › Input. If the bars don't move, the problem is the microphone. Pick the built-in mic and test again; Bluetooth headsets drop to a lower-quality mode when their mic is in use (see Bluetooth mic dictation on Mac).

Words come out in the wrong language. Change Spoken Language under the gear icon in Outlook, or the language list under Keyboard › Dictation for Apple Dictation.

Dictate stops or lags on a bad connection. Outlook's Dictate runs in Microsoft's cloud, so a weak Wi-Fi signal shows up as lag and missed words. Apple Dictation in a downloaded language doesn't have that problem.

Apple Dictation won't start at all. That's a macOS issue rather than an Outlook one. Work through Mac dictation not working.

#When the built-in way is enough

For a two-line reply ("Thanks, Thursday works, see you then"), either built-in is fine. You'll fix a comma, hit Send, done.

Where it gets slow is the email that matters. Spoken emails come out the way you talk: "um", a false start, a time you corrected halfway through. Outlook's Dictate types all of it, and you either speak your punctuation or tidy it afterwards. The more you dictate, the more editing you do.

#Dictating Outlook email with Sayburst

Sayburst is a Mac app that works in Outlook the same way it works everywhere else: click into the message, hold fn, talk, let go. Speech is recognized on your Mac, the fillers come out, and the text is punctuated before it lands. Nothing to sign in to, no Microsoft 365 requirement, and it keeps working on a train with no signal.

Set Outlook to the Email writing mode once and every dictation into it is shaped like an email. Here's a reply to a supplier, spoken naturally:

"hi Marco, uh, thanks for sending the quote over. We can do the first delivery on the ninth, actually no, make that the twelfth, because the warehouse is closed that week. Um, can you confirm the pallet count is still forty? Thanks, Priya"

With the optional on-device Sayburst Writer, Outlook gets:

Hi Marco,

Thanks for sending the quote over. We can do the first delivery on the 12th, because the warehouse is closed that week.

Can you confirm the pallet count is still 40?

Thanks, Priya

The correction from the ninth to the twelfth was resolved, the "um" and "uh" are gone, and the paragraphs are where an email puts them. If a rewrite would ever change a number you said, Sayburst types the cleaned transcript instead.

A few things that help in Outlook specifically:

• Add the names you email most (clients, colleagues, product names) to Sayburst's vocabulary so they're spelled right the first time.
• Use a replacement like "my phone number" for the digits you'd otherwise dictate one by one.
• Clicked away mid-sentence? Sayburst keeps the text. Press ⌃⌥⌘V to paste the last dictation into the message.

#Where your words go

With Outlook's Dictate, your speech is sent to Microsoft and turned into text there; Microsoft says it doesn't store the audio or transcript. With Sayburst, the audio never leaves the Mac. Either way, the email itself is stored by Outlook and your mail provider the moment you save or send it, so dictation choice doesn't change what happens to the message. The local vs cloud dictation guide separates those steps in more detail.

#On Windows?

New Outlook for Windows and Outlook on the web have the same Message › Dictate button, and Windows 11 has voice typing on WindowsH in any text box (it needs an internet connection). Sayburst is a Mac app, so on a PC those are the tools to use.

On a Mac, Sayburst needs Apple silicon and macOS 14 or later, and costs $29 once after the trial. More on the setup in Outlook dictation with Sayburst and our general guide to dictating email on Mac.

Questions people ask

How do I dictate in Outlook on a Mac?

Open a new email or a reply, then choose Message › Dictate or press Option + F1. You need to be signed in with a Microsoft 365 subscription and have an internet connection. Apple Dictation also works in the Outlook message body.

Why don't I see the Dictate button in Outlook?

Microsoft says Dictate is only available to Microsoft 365 subscribers. A standalone Office license, a signed-out app or a reading pane instead of a compose window will all leave you without the button.

Does Outlook dictation work offline?

No. Microsoft's Dictate sends your speech to Microsoft to turn it into text, so it needs a reliable connection. Apple Dictation and Sayburst can transcribe on the Mac itself.

Is there voice to text in Outlook on Windows?

Yes. New Outlook for Windows and Outlook on the web have Message › Dictate, and Windows itself has voice typing on Windows key + H. Sayburst is Mac-only, so on a PC use those.
