+## MABS V4 UR1 known issues and workarounds
+
+Microsoft is recalling the release of Update Rollup 1 for Microsoft Azure Backup Server V4 due to the following known issues:
+
+- Hyper-V scheduled backups take a long time to complete because each backup job triggers a consistency check. 
+
+  **Error Message**: The replica of Microsoft Hyper-V RCT on `<Machine Name>` is not consistent with the protected data source. MABS has detected changes in file locations or volume configurations of protected objects since the data source was configured for protection. (ID 30135)
+
+- MABS console occasionally crashes when SMTP alerts or reports are configured.
+
+  The updated build **Update Rollup 1 Refresh for MABS V4** is released that fixes these known issues. 
+
+>[!Important]
+>If you had installed Update Rollup 1 for MABS V4 (14.0.42.0), we recommend that you install **Update Rollup1 Refresh (14.0.46.0)** on your MABS server and update the protection agents from *KB 5033756*.
+>
+>For any queries or additional information, contact **Microsoft Support**.
+
 ## MABS V4 known issues and workarounds 
 
 If you're protecting Windows Server 2012 and 2012 R2, you need to install Visual C++ redistributable 2015 manually on the protected server. You can download [Visual C++ Redistributable for Visual Studio 2015 from Official Microsoft Download Center](https://www.microsoft.com/en-in/download/details.aspx?id=48145).

For information about the bugs fixed and the installation instructions of MABS V4 UR1 Refresh, see [KB article 5033756](https://support.microsoft.com/home/contact?SourceApp=smcivr2).
+

+
+The following table lists the new features added in MABS V4 UR1:
+
+| Feature | Supportability |
+| --- | --- |
+| Item-level recovery for VMware VMs running Windows directly from online recovery points.    |   Use MARS version *2.0.9251.0* or above for this feature. |
+| Windows and Basic SMTP Authentication for MABS email reports and alerts.      |   This enables MABS to send reports and alerts using any vendor supporting SMTP Basic Authentication. [Learn more](/system-center/dpm/monitor-dpm?view=sc-dpm-2022&preserve-view=true#configure-email-for-dpm). <br><br>   Note that if you're using Microsoft 365 SMTP with a MABS V4 private fix, re-enter the credential using Basic Authentication. |
+| Fall back to crash-consistent backups for VMware VMs.     |     Use a registry key for VMware VMs when backups fail with ApplicationQuiesceFault. [Learn more](backup-azure-backup-server-vmware.md#applicationquiescefault).   |
+| Experience improvements for MABS backups to Azure. |  |
+| List online recovery points for a data source along with the expiry time and soft-delete status.  |  To view the list of recovery points along with their expiration dates, right-click a data source and select **List recovery points**. |
+| Stop protection and retaining data using the policy duration for immutable vaults directly from the console.    |    This helps you save the backup costs when stopping protection for a data source backed up to an immutable vault.

 ### 32-Bit protection agent deprecation
 
-With MABS v3 UR1, support for 32-bit protection agent is no longer supported. You won't be able to protect 32-bit workloads after upgrading the MABS v3 server to UR1. Any existing 32-bit protection agents will be in a disabled state and scheduled backups will fail with the **agent is disabled** error. If you want to retain backup data for these agents, you can stop the protection with the retain data option. Otherwise, the protection agent can be removed.
