|Message:||There is an error in your Outlook Web Access configuration.The character “%5” is not valid for file extensions. It was found in character “%4” of “%3” in element “%2” of the “%1” array in the Outlook Web Access attachment policy for the “%6” virtual directory. This can be corrected by using the Exchange Management Console.|
Outlook Web Access lets you control access to attached documents through the Allow, Block, and Force Save lists. This Error event will occur if a character in a file name extension in one of the attachment policy file name extension arrays is not valid.
Remove the character that is not valid from the file name extension in the affected policy file name extension array.
For information about how to edit the file access policy file name extensions, see How to Manage Public and Private Computer File Access.
