What happens if the Office 365 groups’ storage becomes full?

Office 365 groups' storage allocation empowers users to securely store and share files, fostering seamless collaboration and information exchange. You may face the following issues if the Microsoft 365 groups’ storage is not managed properly.

  • Users will encounter a restriction where they are unable to upload files into the Microsoft 365 groups.
  • Reaching Microsoft 365 group storage limit will make files read-only in SharePoint Online, restricting any further modifications or edits.
  • Users may use personal or unsecured storage locations, which results in potential data breaches and unauthorized access.
  • If it is a mail-enabled group, reaching the Office 365 group storage limit may prevent new emails from being received. Senders will likely receive a notification stating that the “recipient's mailbox is full”.

With AdminDroid, you can check and modify Microsoft 365 group mailbox size, ensuring it aligns with your group’s requirements.

  • Make use of the easy filters functionality to view various storage quotas configured for group mailboxes.
  • Here you can get the entire details of the mailbox size such as prohibit send quota, prohibit send receive quota, archive quota, archive warning quota, issue warning quota, etc.

When will an Microsoft 365 group face storage issues?

Microsoft 365 groups may face storage issues under the following conditions,

  • Modifying documents frequently may increase the SharePoint Online version history, which can consume significant storage space over time.
  • If you set up data retention policies for a longer duration, the Office 365 group storage may pile up faster.
  • Not configuring Exchange Online attachment size limit can contribute to a significant increase in Microsoft 365 group mailbox storage.
  • Uploading larger files without compressing can quickly consume the available storage space.
  • If you have auto-archive settings enabled, emails and other content may be moved to an archive mailbox, increasing the overall storage of Office 365 groups.

What is the storage allocated for Office 365 groups?

Office 365 groups' files utilize the storage allocated to their corresponding SharePoint Online site collections. The overall SharePoint storage capacity depends on the number of licensed users within your organization.

  • By default, each Microsoft 365 organization is provided with 1 TB of storage space. Additionally, there is an additional 10 GB of storage allocated per licensed user.
  • You can add more SharePoint storage to your subscription by purchasing the Office 365 extra file storage add-on.
  • The maximum storage capacity you can configure for a site collection is 25 TB.

How to check the available storage space in SharePoint Online?

  • Login to the SharePoint Online admin center.
  • In the upper right corner of the page, you will find the total SharePoint storage space available in your Microsoft 365 environment.

How to set storage quotas for Microsoft 365 groups?

To prevent the issues faced by storage-exceeded groups in Office 365, you can set up storage quotas for SharePoint sites based on their requirements. To enable manual storage limits,

  • Login to the SharePoint online admin center.
  • Under the Settings tab, select site storage limits and click the Manual option.

Now, you can set up storage quotas for SharePoint sites in the below ways,

  • Using Microsoft 365 Admin Center Navigate to Active teams & groups under Teams & groups. Select the group and click on Edit in Storage Limit option. Enter the desired value in the Maximum storage for this site box and click Save.
  • Using Windows PowerShell Run the below cmdlet to set storage quota in SharePoint Online.
Set-SPOSite -Identity <Site URL> -StorageQuota <value> –StorageQuotaWarningLevel <value>

Here, you can also specify the storage warning quota for the SharePoint sites. You must enter the value in MB.


For Microsoft 365 group mailbox management, run the following PowerShell cmdlet to configure storage quotas for a group mailbox in Exchange Online.

Set-Mailbox -GroupMailbox <Group Display Name> -IssueWarningQuota <value> -ProhibitSendQuota <value> -ProhibitSendReceiveQuota <value> -UseDatabaseQuotaDefaults $false

With AdminDroid, you can create an alert when a SharePoint site storage limit is modified.

  • Follow the steps to create an "Alert" by applying easy filters for the "Site URL" attribute.
  • Pro Tip: By reviewing the Modified Quota Info property, you can determine if the storage quota has been adjusted appropriately based on the requirement of the Microsoft 365 group site.
