When you are starting the Outlook client, the following error occurs:
'.', hex value 0x00, is an invalid character. Line 1, position 1
If this message comes up, please rename the file "CONNECTtoOutlookApplicationConfiguration.xml", you will find this file in the path "%APPDATA%\DocuWare\Connect to Outlook".
Restarting your outlook client afterwards, will recreate the file. Now the message should not occur anymore and you can delete the original file.
This message occurs, because there are invisible hexvalues in the file.
