[Setup Microsoft 365 backup](https://help.syscloud.com/microsoft-365?hsLang=en#setup-microsoft-365-backup) # Microsoft is retiring Exchange Web Services (EWS): what it means for your SysCloud backup  *Applies to: SysCloud Backup for Microsoft 365 (Outlook / Exchange Online)* *Last updated: 12/08/2026* **Summary** - **Your backups keep running.** Mailbox, group mailbox, OneDrive, SharePoint, and Teams backup already use Microsoft Graph and are not affected. - **Three things use EWS today:** email restore, In-Place Archive backup, and Public Folder backup. - **We recommend one action:** Enable EWS on your tenant. **Timeline** | **Date** | **What happens** | | --- | --- | | **End of August 2026** | Recommended deadline to allow EWS API | | **October 1, 2026** | Microsoft starts disabling EWS tenant by tenant | | **October 1, 2026** | EWS blocked for Kiosk, F1, and F3 licensed mailboxes, this cannot be extended | | **April 1, 2027** | EWS permanently disabled, no exceptions | **What's affected** Microsoft is retiring Exchange Web Services (EWS), a legacy API that SysCloud uses for part of its Exchange Online protection. Microsoft begins disabling it on **October 1, 2026** and shuts it down permanently on **April 1, 2027**. This applies to **Exchange Online only**. On-premises Exchange is not affected.   | **SysCloud function** | **Status** | | --- | --- | | Mailbox and group mailbox backup | Not affected, already on Microsoft Graph | | OneDrive, SharePoint, Teams, other apps | Not affected | | Email restore | Uses EWS. Moving to Microsoft Graph, in   testing now. | | In-Place Archive backup | Uses EWS. Microsoft has not released a   Graph replacement. | | Public Folder backup | Uses EWS. Microsoft does not plan to   release a Graph replacement. | **Recommended action** **Enable EWS on your tenant** Complete this before the **end of August 2026**. This keeps email restore, In-Place Archive backup, and Public Folder backup working until **April 2027**. 1. Open **PowerShell** and install the Exchange Online module: "Install-Module ExchangeOnlineManagement -Scope CurrentUser" ![](https://help.syscloud.com/hs-fs/hubfs/EWS_02-png-1.png?width=1587&height=507&name=EWS_02-png-1.png) 2. Connect to Exchange Online using the Microsoft 365 admin account: "Connect-ExchangeOnline -UserPrincipalName \" Complete the Microsoft login and authentication when prompted. ![](https://help.syscloud.com/hs-fs/hubfs/EWS_03-png-1.png?width=1589&height=499&name=EWS_03-png-1.png) ![](https://help.syscloud.com/hs-fs/hubfs/EWS_04-png-1.png?width=1597&height=778&name=EWS_04-png-1.png) 3. Once we enter the password, following is the expected output. ![](https://help.syscloud.com/hs-fs/hubfs/EWS_05-png.png?width=1603&height=778&name=EWS_05-png.png) 4. Check the current EWS configuration: "Get-OrganizationConfig | Format-List EwsEnabled,EwsAllowedAppIDs,EwsApplicationAccessPolicy,EwsAllowList,EwsBlockList" and press enter. 1. If EwsEnabled is empty - EWS has been enabled. Move to step 6 to verify the same. 2. If EwsEnabled is False - EWS is yet to be enabled. Proceed to step 5. ![](https://help.syscloud.com/hs-fs/hubfs/EWS_06-png-1.png?width=1652&height=907&name=EWS_06-png-1.png) 5. If EwsEnabled is False, enable EWS: "Set-OrganizationConfig -EwsEnabled $true" ![](https://help.syscloud.com/hs-fs/hubfs/EWS_07-png-1.png?width=1567&height=334&name=EWS_07-png-1.png) 6. Verify the change by running: Get-OrganizationConfig | Format-List EwsEnabled,EwsAllowedAppIDs,EwsApplicationAccessPolicy,EwsAllowList,EwsBlockList Confirm that EwsEnabled now shows True.  ***Note:** Microsoft will populate your tenant's EWS allow list on September 2026, based on the applications using EWS.*   **If you use Kiosk, F1, or F3 licenses** Microsoft blocks EWS for these licenses from **October 1, 2026**, and the allow list will not override it. **No action is needed from you,** backup for these mailboxes already uses Microsoft Graph, and we are releasing a Graph-based restore path for them **before October 1**.  **If you do nothing** - Data already backed up stays fully retained, searchable, and exportable in all cases. - From the point EWS is disabled in your tenant, email restore will fail, and In-Place Archive and Public Folder backup will pause Other Backup service will continue to work. - You can enable EWS at any time up to **April 1, 2027,** including after a failure and normal operation resumes. **What SysCloud is doing** - **Email restore** is moving to Microsoft Graph and will be released **before October 1, 2026**. A Global Administrator will need to reauthorize the SysCloud app when it ships, we will email you with instructions. - **In-Place Archive backup** will resume as soon as Microsoft provides a Graph API. We are tracking their roadmap. - **Public Folders:** Microsoft's guidance is to migrate public folder content to Microsoft 365 Groups, which SysCloud already backs up through Graph. **Need help?** [Contact our support team.](https://www.syscloud.com/support/ticket/) **Microsoft references** -
