Applies to: Exchange Server SE / 2019 / 2016 / 2013 / 2010 Dial tone recovery is an Exchange Server recovery method that gives users temporary mailboxes so they can continue sending and receiving email while the original mailbox database is being restored. The original version of this article was written for Exchange Server 2010 with Windows Server Backup. Microsoft still documents dial tone recovery for Exchange Server Subscription Edition, Exchange Server 2019, and Exchange Server 2016.

Archive / Legacy Topics, VMware, vSphere
Applies to: VMware vCenter Server 5.1 → 5.1 Update 1 Historical: This article covers the Windows-based vCenter Server 5.1 architecture and its upgrade to vCenter Server 5.1 Update 1.

Restore an Exchange Server Mailbox to a Different Mailbox Using a Recovery Database

Restore an Exchange Server Mailbox to a Different Mailbox Using a Recovery Database

Exchange, Exchange Server SE / 2019 / 2016, High Availability
Applies to: Exchange Server SE / 2019 / 2016 / 2013 / 2010 Exchange Server supports Recovery Databases (RDBs) for restoring mailbox data from a recovered database without interrupting access to the active mailbox database. This applies to Exchange Server Subscription Edition, Exchange Server 2019, and Exchange Server 2016. One useful scenario is restoring the contents of an old mailbox into a different existing mailbox. The recovered database is mounted as an RDB, the source mailbox is identified by its mailbox GUID, and New-MailboxRestoreRequest copies the data into the target mailbox. In This Article 1. What Is a Recovery Database? 2. Prepare the Restored Database 3. Create the Recovery Database 4. Mount and Check the Recovery Database 5. Restore the Mailbox to a Different Mailbox 6.

How to Restore Mailbox Data from an Exchange Recovery Database

Exchange, Exchange Server SE / 2019 / 2016, High Availability

Troubleshoot Exchange Replica Inconsistent Error 30146 in DPM

Troubleshoot Exchange Replica Inconsistent Error 30146 in DPM

Exchange, Exchange Server SE / 2019 / 2016, System Center
Applies to: System Center Data Protection Manager 2025 / 2022 / 2019 | Exchange Server 2019 / 2016 / 2013 Data Protection Manager (DPM) can report an Exchange mailbox database replica as inconsistent when a consistency check fails. One common cause is a version mismatch between eseutil.exe and ese.dll on the Exchange server and the DPM server, especially after an Exchange update. Error ID 30146 is a general data consistency verification failure, so it should not automatically be treated as an Eseutil mismatch. Check the accompanying error details and event logs before applying the fix. In This Article 1. Symptom 2. Why the Eseutil Version Matters 3. Compare the File Versions 4. Update the Files on the DPM Server 5. Run the Consistency Check Again 6. Other Causes of Error…

Moved Mailboxes Appear as Soft-Deleted After a Database Move in Exchange Server

Moved Mailboxes Appear as Soft-Deleted After a Database Move in Exchange Server

Exchange, Exchange Server SE / 2019 / 2016, Migration & Upgrade
Applies to: Exchange Server SE / 2019 / 2016 After moving a mailbox to another mailbox database, you may still see the old mailbox on the source database with a SoftDeleted disconnect reason. This is expected behavior in Exchange Server, including Exchange Server Subscription Edition, Exchange Server 2019, and Exchange Server 2016. The mailbox on the source database is not another active copy of the user mailbox. Exchange keeps the source mailbox temporarily so that its data can still be used for recovery if something goes wrong after the move. In This Article 1. Why This Happens 2. Check Soft-Deleted Mailboxes 3. Check Mailbox Retention 4. Should You Delete It? 5. Permanently Purge a Soft-Deleted Mailbox 6. Key Takeaways 1.

How to Force DFSR SYSVOL Replication in Windows Server

Active Directory, Identity, Windows Server
Applies to: Windows Server 2025 / 2022 / 2019 / 2016 / 2012 R2 / 2012 / 2008 R2 / 2008 Sometimes SYSVOL changes need to replicate immediately between domain controllers instead of waiting for the normal DFS Replication schedule. The original version of this post used dfsrdiag SyncNow to trigger replication for the Domain System Volume replication group. The original method is worth preserving as an operational troubleshooting step, but it is important to separate a normal replication delay from a broken SYSVOL replication state. If SYSVOL or NETLOGON is missing, or DFSR is stopped by an error such as Event ID 2213 or 4012, forcing a connection is not the same as repairing SYSVOL. In This Article 1. Check SYSVOL Before Forcing Replication 2. Trigger DFSR SYSVOL Replication…
