Get a professionally recorded voicemail greeting, perfectly optimized for Microsoft Teams.

Microsoft Teams handles voicemail differently from most VoIP platforms. Instead of uploading an audio file, every user with a Teams Phone license gets two built-in options: a text-to-speech greeting that Teams reads aloud to callers, or a live recording you make yourself. Here's how to access both.
In the same Configure voicemail panel, Teams lets you set a separate out-of-office greeting. You can have it play automatically whenever your Outlook auto-reply is on or when your calendar shows an Out of Office event — perfect for vacations and holidays.
If you manage phones for your whole organization, the Microsoft Teams admin center gives you far more control — including the ability to upload real audio files for your company's main lines.
Admins can also manage user calling policies under Voice → Calling policies to control whether voicemail is available to individual users at all. If a team member reports missing voicemail settings, this is the first place to check.
This is the most common question we hear about Teams — and the answer depends on which greeting you're setting. Here's the honest breakdown:
Microsoft Teams does not currently offer a file-upload button for personal voicemail greetings. You're limited to text-to-speech or the Record a greeting option. But there's a reliable workaround:
For your company's main number, the Teams admin center fully supports uploading audio files (MP3, WAV, WMA) for auto attendant and call queue greetings. If you want a studio-quality first impression for every caller, this is the recommended path — your admin uploads the file once and it plays for every inbound call.

Voicemail requires a Teams Phone license and an enabled calling policy. If the Calls tab or Configure voicemail button is missing, ask your IT admin to verify your license assignment in the Microsoft 365 admin center and your calling policy in the Teams admin center.
Changes can take a few minutes to sync. Make sure you clicked OK/Save after editing, then test by calling your Teams number from another phone. If a text-to-speech greeting isn't playing, check that the correct greeting language is selected in the voicemail settings.
If you used the MP3 playback workaround, adjust speaker volume and microphone gain, and keep the device 10–20 cm from the mic. For best fidelity, use a virtual audio cable to route the file directly into your microphone input instead of playing it through the air.
Confirm the file is MP3, WAV, or WMA and under the size limit. Very high bitrate files sometimes fail — re-export your greeting at 128 kbps MP3, which sounds excellent over the phone and uploads reliably.
Not directly — Teams only offers text-to-speech or live recording for personal greetings. However, you can play a professional MP3 through your microphone during the Record a greeting call, or have your admin upload the audio file to an auto attendant, which fully supports MP3, WAV, and WMA uploads.
Click the three dots (⋯) next to your profile picture, select Settings, then the Calls tab. Scroll down and click Configure voicemail to manage your greeting, call answer rules, and out-of-office greeting.
Voicemail requires a Teams Phone license (Teams Phone Standard or E5) and must be enabled by your organization's admin. Contact your IT administrator to confirm your licensing and calling policy.
Yes. In the Teams admin center under Voice, admins can create auto attendants and call queues that accept uploaded audio files in MP3, WAV, or WMA format — the ideal way to deploy professionally produced greetings company-wide.
In Settings → Calls → Configure voicemail, Teams provides a separate out-of-office greeting field. Type your text-to-speech message and choose when it plays — for example, whenever an Outlook auto-reply is active or a calendar event is set to Out of Office.
