-As a global or SharePoint admin in Microsoft 365, you can set the OneDrive storage space for a specific user.

->[!IMPORTANT]

-> If a user has run out of storage, consider instructing them to proactively identify and review items that are taking up space by following the instructions at [Manage your OneDrive for work](https://support.microsoft.com/en-us/office/manage-your-onedrive-for-work-or-school-storage-31519161-059c-4764-b6f8-f5cd29f7fe68).

-description: "In this article, you'll learn about the modern experience in SharePoint and how you can begin to take advantage of it."

-The modern experience in Microsoft SharePoint is designed to be compelling, flexible, and more performant. The modern experience makes it easier for anyone to create beautiful, dynamic sites and pages that are mobile-ready. But what are the differences between the classic and modern experiences, and how do you go about creating a modern experience for your organization? This guide is a starting point for people familiar with the classic experiences in SharePoint to help you learn about the modern experience and how you can begin to take advantage of it.

-The most effective SharePoint sites (and web sites in general) help visitors find what they need quickly so that they can use the information they find to make decisions, learn about what is going on, access the tools they need, or engage with colleagues to help solve a problem. The fundamental principles and good practices for site and page navigation are equally applicable to both classic and modern SharePoint architectures. However, your options for implementing navigation differ based on the framework for your sites and intranet. For example, the "inherited" navigation experiences available in classic SharePoint site hierarchies (sites with subsites) are not available in the modern experience, but [*hubs*](https://support.office.com/article/fe26ae84-14b7-45b6-a6d1-948b3966427f) provide a great way to achieve the cross-site navigation features previously available in managed navigation and site hierarchies in classic SharePoint.

-No matter which framework you are using, you can use the guidance in [Plan navigation in the modern experience](plan-navigation-modern-experience.md) to help make good decisions for navigation.

-In the classic SharePoint experience, there is a set of default themes and site designs that can require a considerable amount of customization to get them to match your organization's brand. Also, they aren't very responsive, making the experience on different devices inconsistent. Most site branding requires the use of custom master pages or alternate CSS configurations. SharePoint includes an updated set of default site themes and site designs (or templates) that are responsive and look great on any device. With site themes, you can customize your site's logo and colors to match your brand. You can also align the mobile SharePoint app for your users to match your company branding. Site designs provide specific layouts and other functionality for your site. Additional branding can be achieved using custom themes or site designs without worrying about something breaking when SharePoint is updated. To learn more about modern branding options, see [Branding SharePoint sites in the modern experience](branding-sharepoint-online-sites-modern-experience.md).

-If you've implemented publishing sites or publishing-enabled sites in your organization, you know how important it is to create attractive and performant pages to distribute communication to a large number of people. In the modern experience, communication sites make it easy to create beautiful, dynamic, and performant sites and pages that are mobile-ready. There are differences from classic publishing, though, and things you'll want to think about planning your move to the modern experience. For more info, see [Moving from Publishing sites to Communication sites](publishing-sites-classic-to-modern-experience.md).

-Search is an important part of any site ΓÇô you want people to be able to find what they are looking for quickly and easily. SharePoint has both a classic and a modern search experience. Microsoft Search in SharePoint is the modern experience. The most visible difference is that the Microsoft Search box is placed at the top of SharePoint, in the header bar. Another difference is that Microsoft Search is personal and contextual. The results you see are different from what other people see, even when you search for the same words. You will also see different results based on where you are when you search. For example, searching at the root of your tenant looks across all of SharePoint. Searching from a hub finds content in all sites associated to the hub. Searching from an individual site finds content on that site. Searching from a list or library finds content in the list or library. You will also see results before you start typing in the search box, based on your previous activity and trending content in Microsoft 365, and the results update as you type. To learn more about the Microsoft Search experience for users, see [Find what you need with Microsoft Search](https://support.office.com/article/d5ed5d11-9e5d-4f1d-b8b4-3d371fe0cb87). There are other differences, especially around customization. To decide which experience your organization should use, see [When to use which search experience](get-started-with-modern-search-experience.md).

-SharePoint continues to provide both SharePoint groups and security groups maintained by Microsoft Entra ID. Microsoft 365 also provides a third grouping option for SharePoint, [Microsoft 365 groups](https://support.office.com/article/b565caa1-5c40-40ef-9915-60fdb2d97fa2). Microsoft 365 groups are similar to security groups, although Microsoft 365 groups include many additional benefits. Microsoft 365 groups are provided a group email address and additional tools such as a group calendar, notebook, Planner, and a SharePoint Team site. Users assigned to a Microsoft 365 group may also be classified as either a group owner or a group member, in comparison to security groups where all group members have equal access under the group. To learn about the differences, benefits, and best practices for permissions and sharing in the modern experience, see [Sharing and permissions in the SharePoint modern experience](./modern-experience-sharing-permissions.md).

-Classic SharePoint publishing sites can use a feature called [variations](https://support.microsoft.com/office/da0b5614-8cf5-4905-a44c-90c2b3f8fbb6) to create a site that supports multiple languages. Modern communication sites leverage a multilingual experience to make content in your intranet sites available in multiple languages. User interface elements like site navigation, site title, and site description can be shown in the user's preferred language. Additionally, you can provide pages and news posts on communication sites that you translate and that are shown in the user's preferred language. One of the most important differences in the modern experience is that, unlike the variations feature, which creates a separate *subsite* for each language, the modern multilingual experience creates a corresponding page in the same site, but in a language-specific *folder* in the Site Pages library. To learn more, see [Create modern multilingual communication sites, pages, and news](https://support.office.com/article/create-multilingual-communication-sites-pages-and-news-2bb7d610-5453-41c6-a0e8-6f40b3ed750c).

-OneDrive access restriction is applied when a user attempts to open a OneDrive or access a file. Users not members of the specified security group can still see files in search results if they have existing direct permissions to the file. However, they won't be able to access the file if they're not part of the security specified group

-Follow these steps to specify individual site storage limits when your storage management option is set to "manual." We recommend that you also set an email alert so that you and other site admins can be notified when sites are nearing the storage limit. To learn how to set the default storage limit for new sites, see [Manage site creation](manage-site-creation.md).

-2. Under **Site Collection Administration**, select **Storage Metrics**.

-> [!NOTE]

-> The **Disable OneDrive** check box has no effect. Use the "Create Personal Site" check box to specify the security groups that have permission to create a OneDrive.

- **To prevent users from downloading the OneDrive sync app**

-This article describes how to enable Microsoft SharePoint and Microsoft OneDrive integration with Microsoft Entra B2B.

-Enabling this integration doesn't change your sharing settings. For example, if you have site collections where external sharing is turned off, it will remain off.

-Once the integration is enabled you and your users don't have to reshare or do any manual migration for guests previously shared with. Instead, when someone outside your organization clicks on a link that was created before Microsoft Entra B2B integration was enabled, SharePoint will automatically create a B2B guest account. This guest account is created for the user who originally created the sharing link. (If the user who created the link is no longer in the organization or no longer has permission to share, the guest won't be added to the directory and the file will need to be reshared.)

-You can turn off OneDrive sync from all the SharePoint libraries in your organization by using this [Set-SPOTenant](/powershell/module/sharepoint-online/set-spotenant) PowerShell cmdlet to remove the OneDrive sync button:

-```PowerShell

-Set-SPOTenant -HideSyncButtonOnTeamSite $true

-```

-To create a site collection in the new SharePoint admin center, go to <a href="https://go.microsoft.com/fwlink/?linkid=2185220" target="_blank">**Active sites**</a>, and then select **Create** on the command bar. To create a classic site, select **Other options**.

-description: "In SharePoint, if you share with a user who is not in the directory, they are sent a one-time code that they can use to verify their identity."

-In SharePoint, if you share with a person who is not in the directory, they're sent a one-time code that they can use to verify their identity.

-This article describes the current default one-time-passcode experience. However, we recommend that you enable [SharePoint and OneDrive integration with Microsoft Entra B2B](sharepoint-azureb2b-integration.md), which will replace this experience.

-Recipients of secure external sharing who also use Microsoft 365 in their organization can sign in using their work or school account to access the document. After they have entered the one-time passcode for verification the first time, they will authenticate with their work or school account and have a guest account created in the host's organization. IT admins can manage them like any other guest account in their directory.

- When you use the Share dialog box to share with "specific people" and the recipients are all outside the organization, then a secure link will be created and the specified email addresses will be secured, or added, to the link. This appears in audit logs in the following ways.
