-# Introduction to SharePoint and OneDrive in Microsoft 365

-# Manage site storage limits

-The amount of Microsoft SharePoint space your organization has is based on your number of licenses (see [SharePoint Limits](/office365/servicedescriptions/sharepoint-online-service-description/sharepoint-online-limits)). If you're a Global Administrator in Microsoft 365, you can [Add storage space for your subscription](/office365/admin/subscriptions-and-billing/add-storage-space) if you run out.

- >[!NOTE]

- > If you have Office 365 operated by 21Vianet (China), [sign in to the Microsoft 365 admin center](https://go.microsoft.com/fwlink/p/?linkid=850627), then browse to the SharePoint admin center and open the Active sites page.

- > If you set site storage limits in PowerShell, you enter them in MB. The values are converted and rounded down to the nearest integer to appear in GB in both the SharePoint admin center. So a value of 5000 MB becomes 4 GB. The minimum storage limit is 1 GB, so if you set a value of less than 1024 MB by using PowerShell, it will be rounded up to 1 GB.

-

-

-### Monitor site storage limits by using PowerShell

-If you manage storage limits manually, you need to regularly monitor them to make sure they aren't affecting site performance. We recommend that you also set up your own alert emails to notify site admins before a site reaches the limit. The built-in storage quota warning emails are typically sent weekly for sites that have reached the specified warning level. So site admins often receive the storage quota warning email too late. For example, if the Disk Quota Warning timer job (which triggers the warning email) is scheduled weekly and sends the email warning every Sunday, but a site reaches the quota warning limit on Monday, the site admin doesn't receive the alert email for six days. This site could reach the maximum storage limit and be set to read-only before the site admin receives the alert email.

-

-You can use the following Microsoft PowerShell script to monitor your sites. This script pulls the data, composes, and then sends a storage warning alerts to the site admin.

-

-1. [Download the latest SharePoint Online Management Shell](https://go.microsoft.com/fwlink/p/?LinkId=255251).

- > [!NOTE]

- > If you installed a previous version of the SharePoint Online Management Shell, go to Add or remove programs and uninstall "SharePoint Online Management Shell."

-2. Connect to SharePoint as a [Global Administrator or SharePoint Administrator](./sharepoint-admin-role.md) in Microsoft 365. To learn how, see [Getting started with SharePoint Online Management Shell](/powershell/sharepoint/sharepoint-online/connect-sharepoint-online).

-

-3. Copy the following text with the variable declarations, and paste it into a text editor, such as Notepad. You must set all of the input values to be specific to your organization. Save the file, and then rename it "GetEmailWarning.ps1".

-

- > [!NOTE]

- > You can use a different file name, but you must save the file as an ANSI-encoded text file with the extension .ps1.

-

- ```powershell

- #Connect to SharePoint admin center using an admin account

- #Specify the URL to your SharePoint admin center site, e.g. https://contoso-admin.sharepoint.com

-

- $url = 'https://contoso-admin.sharepoint.com'

-

- #Specify a folder path to output the results into

- $path = '.\'

-

- #SMTP details

- $Smtp = '<SmtpServer>'

- $From = '<SenderEmailAddress>'

- $To = '<RecipientEmailAddress>'

- $Subject = 'Site Storage Warning'

- $Body = 'Storage Usage Details'

-

- if($url -eq '') {

- $url = Read-Host -Prompt 'Enter the SharePoint admin center URL'

- }

-

- Connect-SPOService -Url $url

-

- #Local variable to create and store output file

- $filename = (Get-Date -Format o | foreach {$_ -Replace ":", ""})+'.csv'

- $fullpath = $path+$filename

-

- #Enumerating all sites and calculating storage usage

- $sites = Get-SPOSite

- $results = @()

-

- foreach ($site in $sites) {

- $siteStorage = New-Object PSObject

-

- $percent = $site.StorageUsageCurrent / $site.StorageQuota * 100

- $percentage = [math]::Round($percent,2)

-

- $siteStorage | Add-Member -MemberType NoteProperty -Name "Site Title" -Value $site.Title

- $siteStorage | Add-Member -MemberType NoteProperty -Name "Site Url" -Value $site.Url

- $siteStorage | Add-Member -MemberType NoteProperty -Name "Percentage Used" -Value $percentage

- $siteStorage | Add-Member -MemberType NoteProperty -Name "Storage Used (MB)" -Value $site.StorageUsageCurrent

- $siteStorage | Add-Member -MemberType NoteProperty -Name "Storage Quota (MB)" -Value $site.StorageQuota

-

- $results += $siteStorage

- $siteStorage = $null

- }

-

- $results | Export-Csv -Path $fullpath -NoTypeInformation

-

- #Sending email with output file as attachment

- Send-MailMessage -SmtpServer $Smtp -To $To -From $From -Subject $Subject -Attachments $fullpath -Body $Body -Priority high

- ```

-4. Where:

- - **$url** is the URL of your SharePoint admin center. If the `$url` variable is left empty, you will be prompted to enter the URL of your admin center site.

-

- - **$path** is the file system path you want the CSV file to output to.

-

- - **\<SmtpServer\>** is the name of your mail server.

-

- - **\<SenderEmailAddress\>** is the Global Administrator or SharePoint Administrator account that appears in the From line in the warning email.

-

- - **\<RecipientEmailAddress\>** is the admin account that will receive the email warning.

-

-5. In SharePoint Online Management Shell, change to the local directory where you saved the script file.

-

- ```

- ./GetEmailWarning.ps1

- ```

-After the script successfully completes, a text file is created in the location that you specified in the **$path** variable in the script.

-> [!NOTE]

-> If you get an error message about being unable to run scripts, you might need to change your execution policies. For info, see [About Execution Policies](/powershell/module/microsoft.powershell.core/about/about_execution_policies).

-description: "Learn how global and SharePoint admins can change the organization-level sharing settings for SharePoint and OneDrive in Microsoft 365."

-# Manage sharing settings

-This article describes how Global Administrators and SharePoint Administrators in Microsoft 365 can change their organization-level sharing settings for Microsoft SharePoint and Microsoft OneDrive. (If you want to share a file or folder, read [Share SharePoint files or folders](https://support.office.com/article/1fe37332-0f9a-4719-970e-d2578da4941c) or [Share OneDrive files and folders](https://support.office.com/article/9fcc2f7d-de0c-4cec-93b0-a82024800c07).)

-To change the sharing settings for a site after you've set the organization-level sharing settings, see [Change sharing settings for a site](change-external-sharing-site.md). To learn how to change the external sharing setting for a user's OneDrive, see [Change the external sharing setting for a user's OneDrive](/onedrive/user-external-sharing-settings).

-2. Under **External sharing**, specify your sharing level for SharePoint and OneDrive. The default level for both is "Anyone."

- > The SharePoint setting applies to all site types, including those connected to Microsoft 365 groups.

-|**New and existing guests** <br/> | Require people who have received invitations to sign in with their work or school account (if their organization uses Microsoft 365) or a Microsoft account, or to provide a code to verify their identity. Users can share with guests already in your organization's directory, and they can send invitations to people who will be added to the directory if they sign in. For more info about verification codes, see [Secure external sharing in SharePoint](what-s-new-in-sharing-in-targeted-release.md)<br/><br/>Invitations to view content can be redeemed only once. After an invitation has been accepted, it can't be shared or used by others to gain access. <br/> |

-If people who use a verification code have selected to "stay signed in" in the browser, they must prove they can still access the account they used to redeem the sharing invitation.

-Choose the option you want to show by default when a user gets a link.

-> This setting specifies the default for your organization, but site owners can choose a different default link type for a site.

- > If you select "Anyone with the link," but the site or OneDrive is set to allow sharing only with guests who sign in or provide a verification code, the default link is "Only people in your organization." Users need to change the link type to "Specific people" to share files and folders in the site or OneDrive externally.

-### Advanced settings for "Anyone" links

-**Link expiration** - You can require all "Anyone" links to expire, and specify the maximum number of days allowed. If you change the expiration time, existing links will keep their current expiration time if the new setting is longer, or be updated to the new setting if the new setting is shorter.

-**Link permissions** - You can restrict "Anyone" links so that they can only provide view permission for files or folders.

-## Other

-**Display to owners the names of people who viewed their files**

-On the classic Sharing page, you can limit external sharing by security group and shorten sharing links or change their default permission.
