Exchange Object Recovery Failing


Bedders

Recommended Posts

We are seeing the issue described in https://helpcenter.nakivo.com/display/KB/Cannot+Open+Database+During+Microsoft+Exchange+Mailbox+Recovery, that is when I go to Exchange Recovery, I select a server & a date to restore from, expand the database and click on a user - I see this error:

Database cannot be opened.
Generic error happened while opening.
Failed to complete recovery. Exception calling 'AutodiscoverUrl' with '2' argument(s): 'The Autodiscover service couldn't be located.'
Export Exchange certificates from the Exchange admin center and add them to Trusted Root Certification Authorities Store via MMC.

I have tried the first recommended fix on the other page (https://helpcenter.nakivo.com/display/KB/Mailbox+Processing+Failed+Because+Autodiscover+Service+Could+Not+Be+Located), adding the security certificates to the certificate store, and it still isn't working.

I'm hoping to avoid entering the registry key suggested because I understand it opens up additional vulnerabilities on our Exchange server (see https://msrc.microsoft.com/update-guide/vulnerability/CVE-2018-8581)

Is there any other possible way to allow us to restore specific Exchange objects?

@BeddersThank you for your interest in NAKIVO!

There is another solution called "BackConnectionHostNames" (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0)

Simply add this Key with your Exchange-Hostname (e.g., mail.domain.com) via Powershell:

New-ItemProperty HKLM:\System\CurrentControlSet\Control\Lsa\MSV1_0 -Name "BackConnectionHostNames" -value "mail.domain.com" -PropertyType MultiString

No IISReset is required.

We are looking forward to hearing from you.
