When trying to open the correct Autodiscover/EWS URL manually in a browser from the same server on which GFI Archiver is installed it fails to open (e.g. with a 404 not found error). In the above example, it would be: https://mailserver.domain.com/Autodiscover/Autodiscover.xml

Note: In GFI MailArchiver 2013 or older, the logs mentioned above were found in ..\Core2\DebugLogs.

This article gives a resolution to these errors. 

 

Root Cause

IIS bindings are configured in a way that the required sites (Autodiscovery/EWS) are not reachable from GFI Archiver.

 

Environment

  • GFI Archiver
  • Microsoft Exchange 2007 or later

 

Solution

  1. Open the IIS 7 Manager on the Microsoft Exchange server.
  2. Expand the nodes and mark the Default Web Site.
  3. Open the Bindings.
  4. Check if the following binding exists:
    • Type = https
    • IP address = All Unassigned
    • Port = 443
    • SSL certificate = Microsoft Exchange (or your own certificate)
  5. If this sitebinding is missing, add this binding.
  6. Configure the bindings in a way that the site is reachable for GFI Archiver.
