| description | Learn to change the default theme for the top of the navigation bar in Microsoft 365 and customize it to match your company logo or color. |
Check out all of our small business content on Small business help & learning.
As the admin of your organization, you can create multiple themes for the people in your organization, and select which themes apply to different members of your organization. The organization theme is what appears in the top navigation bar for people in your organization.
You can add or update a default theme that applies to everyone in your organization. You can also create up to four additional group themes that can be assigned to multiple Microsoft 365 groups.
-
In the admin center, go to the Settings > Org Settings page, and then choose the Organization profile tab.
-
On the Organization profile tab, select Custom themes.
-
Choose Add theme and add the required info for the tabs.
All organization themes can be customized using the following tabs.
Tab What can you do? General Modify a theme name and assign to up to five groups (if applicable). Logos Add your organization logo, including alternate logo for dark theme. Colors Customize a color scheme by specifying navigation bar, accent, text and icon colors.
Your experience on the General tab depends on whether you're adding or modifying the default theme or a group theme.
The default theme is the first theme displayed.
- If you previously customized a theme for your organization, select Default Theme and use one of your saved customizations, or, select Add theme.
- On the General page, you can prevent users from overriding their theme and show the user’s display name.
- Select Save to save your changes.
Important
The default theme is unique, it can't be renamed and applies to everyone within your organization. To delete the default theme, you have to delete all other themes first.

On the Logos page, you can add your logos, and specify the URL where users will navigate to when they select the logo.
- Default logo: Add a URL location that points to your logo. Make sure that the URL uses HTTPS. Add an HTTPS image url that allows anonymous access and doesn't require authentication. For default theme, you also have an option to upload a logo image that is less than 10kb. Your default logo can be in the JPG, PNG, GIF, or SVG format. For SVG images, they will be resized to fit 24 pixels vertically. JPG, PNG, GIF images will be scaled to fit 200 x 48 pixels. Logo aspect ratio will always be preserved.
- Alternate logo: Add a URL location that points to your logo. Your alternate logo should be optimized for use in Microsoft 365 dark themes. Same requirements as the default logo.
- On-click link: Add a URL location that points to your logo. You can use your logo as a link to any company resource, for example, your company's website. If you don’t select a URL location for your logo, it’ll default to the Microsoft 365 home page.
Select Save to save your changes.

You can remove your logos at any time. Just return to the Logos page and select Remove.
Note
The Microsoft 365 suite header is designed to accommodate a variety of screen sizes, window sizes, and display settings. The responsive behavior of the suite header sometimes results in the logo not showing to give space to other capabilities shown on the suite header. To reduce the likelihood of this behavior a narrower image file is recommended.
On the Colors page, you can set the default colors and choose which logo should be used.
-
Navigation bar color: Select a color to use for the background of the navigation bar. The navigation bar appears at the top on every page.
-
Text and icon color: Select a color to use for the text and icons on the top navigation bar.
-
Accent color: Pick one that shows up well on a white or light background. The accent color is used to color some links and buttons that show up on a white or light background. For example, the accent color is used to color elements in a user's inbox and on their microsoft365.com portal page.
-
Reset color: Select this link to reset colors to the default colors.

The default theme will continue to be shown to all employees. Adding a new group theme will only be made available to the Microsoft 365 groups associated with that theme.
Only global admins can customize company themes. Global readers have read-only access.
Up to five themes can be created. A default theme and four group themes.
No, new group themes must be mapped to one or more Microsoft 365 groups and not security groups or distribution groups.
No, new group themes must be mapped to one or more Microsoft 365 groups. Users who are members of the Microsoft 365 group will get the theme applied to their group. You can create and add new members to a Microsoft 365 Group by going to the Settings > Groups in the admin center.
Users who are assigned to multiple group themes will be shown the default theme.
The default theme can only be deleted once all group themes are deleted. Make sure you delete all group themes before you try to delete the default theme.
Make sure the logo you’re using is specified as a publicly addressable URL. Follow these steps for uploading logos to Azure Blob Storage or the Office 365 Content Delivery Network with SharePoint Online.
The recommended contrast ratio between text, icon or button color and background color is 4.5:1. You can override this recommendation and still save your theme as this is not a requirement.
Any theme appears in the top navigation bar for everyone in the organization as part of the Microsoft 365 suite header.
