Answer

PROBLEM

When Installing GFI MailEssentials, the Post-Installation Wizard does not have the option to specify the name of the sub-folder, if the default anti-spam action is set to “Deliver to Exchange Subfolder”. As a result, the sub-folder within Microsoft Exchange will be created automatically, but under a different, incorrect node.
It will be created with the default value: Inbox/Spam or Inbox/Suspected Spam. This will cause a confusion on non-English environments, where the Inbox has a different name. (e.g. Posteingang).

ENVIRONMENT

• All supported versions of GFI MailEssentials, installed directly on the Microsoft Exchange server
• Microsoft Exchange 2007 and above, non-English versions

SOLUTION

Correct the path of the sub-folder in each filter within the GFI MailEssentials Configuration, to match the locale of Microsoft Exchange.
On a German installation for example, change from Inbox/Suspected Spam to Posteingang/Spam.
After this, the incorrect folder can be deleted manually from Outlook.


Note:
The subfolder will be created automatically, if the first email is blocked by the Anti-Spam filter.
 

CAUSE

This is caused by the Inbox being named something other then "Inbox" in non-English environment.
