    When mailboxes are moved, the original mailbox is soft-deleted on the origin database. This is by design

    • When a mailbox is moved to a different mailbox database, Exchange doesn't fully delete the mailbox from the source mailbox database when the move is complete. Instead, the mailbox in the source mailbox database is switched to a soft-deleted state. Like disabled mailboxes, soft-deleted mailboxes are retained in the source database either until the deleted mailbox retention period expires or until the Remove-StoreMailbox cmdlet is used to purge the mailbox.

  • Hi,

    Can the migrated user connect to Outlook or OWA normally?

    As above mentioned,the original mailbox is soft-deleted on the origin database. 

    Please run the following command to identify soft-deleted mailboxes in your organization. Get-MailboxDatabase | Get-MailboxStatistics | Where { $_.DisconnectReason -eq "SoftDeleted" } | ft DisplayName,Database,DisconnectDate

    I suggest you also have a look at the following thread:

  • Ok, my ideda was optimalization one big db to more smaler db for beter replication DAG on dedicated place... Now I have more big db and must wait a time for deleted soft-deleted state.. I hope so for shrink size db after retention period.. Maybe is not a problem becouse replication copy only changes.. It is right?

    The database will not shrink on disk. If you moved all the mailboxes from it and do not need it, you can simply delete it. 

    You can purge soft-deleted mailboxes otherwise or wait till the deleted mailbox retention time expires.

  • replication is really log shipping. So whatever makes log on original will ship the transaction log to the copy.
