Bedders Posted September 29, 2022 Posted September 29, 2022 (edited) 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?

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. Quote
luis sanchez2 Posted July 11, 2025 Posted July 11, 2025 Hi, I have the same problem, but I have a Nakivo appliance. How can I upload the certificate to the Linux appliance? Where should I add "BackConnectionHostName" in the Exchange Server or my local computer? Quote

You need to import the certificates to the Exchange server as described in the following article: https://helpcenter.nakivo.com/Knowledge-Base/Content/Recovery-Issues/Mailbox-Processing-Failed-Because-Autodiscover-Service-Could-Not-Be-Located.htm Quote
