Exchange Mailbox Poisoned

You are seeing this error because the mailbox that has failed to migrate is in a poisoned state and has been quarantined. A mailbox may be tagged as poisoned for numerous reasons such as corrupt attachments and emails or a virus or malware has been found in the mailbox. You have two options, you can either delete the mailbox or remove the poisoned state of the mailbox.

Removing a Mailbox From Quarantine

To remove a mailbox from quarantine in Exchange 2010 and Exchange 2013 we first need to get its GUID. To do so run the following command. Replacing username with the username of the mailbox that has been quarantined. Then make a note of the GUID of the mailbox.

get-mailbox statistics -identity  | fl

Now that you have the GUID of the mailbox we need to browse to the following key in the registry and remove the key that mentiones the GUID.

HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\\Private-{db guid}\QuarantinedMailboxes\{the mailbox guid}

One you have removed the offending GUID then you need to restart IIS with the following comand.

iisreset

Once done you will be able to migrate the mailbox as it is no longer quarantined.

    Hey,

    Thank you so much for your info. The only think I would add would be that after deleting the registry key, the only way you can get the mailbox out quarantined status is by restarting the information store service.

    Thanks again, it helped me a lot!!!

    Solution:
    Step 1: check for database location run eseutil.exe

    in my case:

    “C:\Program Files\Microsoft\Exchange Server\V15\Bin\eseutil.exe” /mh “c:\db\Mailbox Database xxxxxxxxxx.edb”

    “C:\Program Files\Microsoft\Exchange Server\V15\Bin\eseutil.exe” /p “c:\db\Mailbox Database xxxxxxxxxx.edb”

    step 2: Space and log file: Make sure you have enough space on your hard drive which is holding your database and log files. Move log files which are older then six month to another drive.

    Step 3: Mount database again. (At this stage my problem is solved, hope the same for you as well.)

    Regards,
