Product
Outlook for Microsoft 365

not provided
Scenario
Composing an email in Outlook using a custom font like Avenir Book.
Observed behavior
Custom fonts added via Word's Explore Fonts feature do not automatically sync or become available in Outlook's font picker.

Solution 1Recommended

Install the Custom Font at the Operating System Level

To make a custom font available in Outlook, you must install the font file directly into your computer's operating system rather than relying on Word's cloud font feature.

Outlook for Microsoft 365 does not have a built-in feature to import custom fonts directly into email messages. It relies strictly on the fonts installed at the system level. Fonts added via Word's Explore Fonts are often cached locally for Word and do not automatically transfer to Outlook.

1
Download the font file

Obtain the custom font file (e.g., Avenir Book.ttf or .otf) from a trusted font provider and save it to your local drive.

2
Install the font on Windows

Right-click the downloaded font file and select 'Install' or 'Install for all users' from the context menu.

3
Install the font on Mac

Double-click the font file to open Font Book, then click the 'Install Font' button in the preview window.

4
Restart Outlook

Close and reopen Outlook for Microsoft 365 so the application can refresh its font list and load the newly installed system font.

Recipient Visibility Warning: Even after you successfully install and use the custom font in Outlook, your email recipients will only see the font if it is also installed on their devices. Otherwise, their email client will replace it with a default fallback font (like Calibri or Arial).

Frequently Asked Questions

Why do fonts added in Word not sync with Outlook?

Word's 'Explore Fonts' feature utilizes cloud fonts that are often downloaded and cached specifically for Word. Because Outlook relies strictly on fonts installed at the operating-system level, it cannot access these Word-specific cloud fonts automatically.

Will the recipient see the custom font I use in my Outlook email?

Generally, no. Standard email clients do not embed font files within the email itself. The recipient will only see the custom font if they also have that exact font installed on their device. For important communications, it is best to stick to standard web-safe fonts.

Can I embed custom fonts into an Outlook message?

No, Outlook for Microsoft 365 does not support embedding custom font files directly into email messages. If exact typography is critical, you can either save your text as an image and insert it into the email, or use a dedicated third-party email marketing service that supports HTML web fonts.
