Hello,

We have in our organization few mailboxes (Exchange 2010) which are enabled for Litigation Hold for a purpose. Now since we are moving to Exchange 2013, need to understand what happens to those mailboxes after migration.

Neilesh,

Litigation hold will remain enabled and all the restrictions of litigation hold will be there on the mailbox. Hope this answer your question. Tha

Thanks for your reply Riaz Javed Butt.

One more thing.. Could you please tell me how do I search for deleted mails in these mailboxes.

Hi Neilesh,

Below cmdlet would give you the actual mailbox size including the deleted items(changed hold items etc)

Get-MailboxFolderStatistics -Identity contoso\chris | Select Name,FolderSize,ItemsinFolder


Recoverable Items            127.5 KB (130,553 bytes)            54
Deletions                    0 B (0 bytes)                        0
Purges                       0 B (0 bytes)                        0
Versions                     0 B (0 bytes)                        0

Litigation hold is not going to allow user to delete any email. If an email is being deleted then even from deleted items then you can perform eDiscovery to search emails sent and received by abc@domain.com user and export the result into PST. Hope this answers your question.

Kindly mark this as answer if your question is being answered. Thanks.
