If you’ve got an Office 365 tenant or an existing tenant with an Office 2017 tenant, you can now create a custom logo with the Office branding.
The Office branding was introduced to the public in 2015.
The Office logo is designed to stand out in your inbox and desktop, but it also can be used in Google Drive, Gmail, YouTube, Google Maps, and many other apps.
To use a custom Office logo, you must have an Office app installed on your device.
If you don’t have an app, you will need to create one from the Office logo file in your account.
The office logo is one of many Office branding files available for download, but you can also use a Google Docs template for a custom office logo.
If your logo file is large, you’ll want to use a .xls file that has a header image that’s similar to your Office logo.
The new Office branding will be available to Office 365 users in the Office 2018 update, and is available to new and existing Office 365 customers.
