Dictate in · Outlook
Outlook’s own Dictate needs a Microsoft 365 subscription, and as of August 2026 the button is missing from New Outlook for Mac altogether. Here is where it went, and how to dictate into a message either way.
The hook
Most people searching this are not looking for instructions. They are looking for a button they used last month. In legacy Outlook for Mac it sits on the Message tab of the ribbon, with ⌥F1 as its shortcut. In New Outlook for Mac, checked in August 2026, it is not there, and Microsoft has spent the past while migrating Mac users onto that new version.

First, the built-in way
The route
Open a new message, click into the body, then choose Dictate from the Message tab or press ⌥F1. Grant the microphone prompt when it appears and start talking. Say punctuation marks out loud if the automatic punctuation is not catching them.
The strings
An active Microsoft 365 subscription on the signed-in account, an internet connection (the audio is processed on Microsoft’s servers), and microphone permission for Outlook. The same three conditions apply in Word, which we go through in more detail on dictating in Microsoft Word.
The other way
A system-wide dictation key does not care which Outlook you are in, whether you pay Microsoft, or whether the toolbar has been redesigned since last quarter. It types into the field that has the cursor. Dictate is our app, and this is what using it in a compose window looks like.
Open a compose window and click the body, or the subject line if that is what you are writing. There is no button to find and no toolbar to wait for. Whatever has the blinking cursor is where the words will go.
Hold your hotkey down for as long as you are speaking. Recording ends when you let go, so a pause in the middle of a sentence costs nothing. Say the greeting, the message, and the signoff in one pass and fix names afterwards.
The text is inserted at the cursor through the macOS Accessibility API, with a paste fallback for apps that will not take it directly. Read it once, because dictation gets names and figures wrong in ways spellcheck will not catch, then send.
What lands in the message body
Thanks for sending the deck through. Thursday at two works on my side. I will bring the revised numbers and we can decide on the timeline in the room.
Spoken in one held press, with pauses, and inserted punctuated. Audio travels over TLS, is transcribed on our servers, then discarded. History keeps the transcript text and its metadata, never the recording. Dictate needs a connection to transcribe and works in English only.
Troubleshooting
Three causes account for most of it, in the order worth checking. The first one is the answer more often than the other two together.
Fix 01
macOS holds microphone access per app, and Outlook is its own entry. Switch it on, then quit Outlook completely (Command Q, not just the window) and reopen it. macOS picks the permission up when the app next launches, which is why granting it and carrying on rarely works.
A system-wide dictation tool is a separate entry in the same list, so granting one does nothing for the other.

Fix 02
Outlook’s Dictate is a Microsoft 365 feature. If the account signed into Outlook has no active subscription, the control is either dim or absent, and no permission change will bring it back.
If the subscription is fine, the next suspect is the network. Dictate in Microsoft’s apps sends audio to Microsoft’s servers, so a dropped connection, a captive portal, or a proxy that blocks the speech endpoint stops it mid-sentence.
Applies to
Word has the same two requirements and the same failure modes. The longer version is on the Word page.
Fix 03
The versions look close enough that people spend twenty minutes hunting a control that was never drawn. Outlook has carried a New Outlook toggle in the top right of the window; with it off you are in the legacy app, where the Message tab still carries it.
Whether you can still switch back depends on your Outlook version and, on a work account, on what your administrator permits. It is worth knowing about, but it is a way to postpone the migration rather than a way to keep dictating.
Legacy shortcut
⌥F1
Nothing at all in New Outlook for Mac, checked August 2026.
Still nothing, or is dictation dead across the whole Mac rather than just in Outlook? The wider suspect list is in Mac dictation not working, and the mechanics of a held key are in push to talk dictation on a Mac.
The trade
It is not free
Apple Dictation is already on your Mac and costs nothing, and for two-line replies it is enough. It stops after about 30 seconds without speech, which is the point most people leave it.
It needs a connection
Transcription happens on our servers, not on your Mac. Offline, only the signed subscription check still works. If you need dictation on a plane, a local-model app is the honest answer.
English only
Dictate transcribes English. If your mail is in more than one language, this is not the tool for that half of it. We would rather say so here than after you have paid.
The short version
Dictate costs $8 a month, flat, monthly only, and the same hotkey works in either Outlook, in Gmail, and in Apple Mail. The rest of the app guides are in dictate in any Mac app. Unused subscriptions are refunded in full; once you have transcribed something, that month is not refundable.
Dictating in Outlook
The missing button, the Microsoft 365 requirement, and the microphone permission.
Checked August 2026: the Dictate button is absent from New Outlook for Mac. It exists in legacy Outlook for Mac, on the Message tab of the ribbon, and Microsoft has been moving Mac users onto New Outlook. If your Outlook was switched over, the button did not break, it is not there.
Yes. Microsoft lists Dictate as a Microsoft 365 feature, so a one-off Office licence does not include it. It also needs an internet connection, because the audio is processed on Microsoft’s servers.
Click into the message body and use Apple Dictation, which is free and built into macOS, or a system-wide hold-to-talk app such as Dictate at $8 a month. Both type into whichever field has the cursor, so neither one cares which Outlook you are running.
Open System Settings, then Privacy and Security, then Microphone, and switch Outlook on. macOS picks up a new microphone permission when the app next launches, so quit Outlook completely and reopen it before testing again.
Outlook has carried a New Outlook toggle in the top right of the window, and switching it off has been the usual way back. Whether that is still available to you depends on your Outlook version and, on a work account, on what your administrator allows. Treat it as a temporary answer rather than a plan.
Yes, and in Outlook on the web. Dictate types into whatever text field has focus rather than hooking into Outlook, so the compose window in either version behaves the same. It needs a connection: audio goes over TLS, is transcribed on our servers, then discarded. English only.
