AttachmentExtractor fails to upload large files


AttachmentExtractor fails to upload files exeeding two megabytes of size (The actual size being blockes depends on various parameters and might actually be lower than the set value).

Check, if you see a message similar to the following in the event log or the log overview of the service configuration:

The request message is to big. The server does not allow messages larger than 2097152 bytes.

This is indicating, that the default upload method is not working due to server side message size restrictions.


  • Note your servicename, as you have entered it, when creating the service. (e.g. MyService)
  • Open the registry editor on the machine, where the AttachmentExtractor service is installed.
  • Open the following key : HKEY_LOCAL_MACHINE\SOFTWARE\PTM EDV-Systeme\AttachmentExtractorserver\Configurations
  • Find the key, named euqal to your servicename (e.g. HKEY_LOCAL_MACHINE\SOFTWARE\PTM EDV-Systeme\AttachmentExtractorserver\Configurations\MyService)
  • Find the following StringValue UseSP15Upload
  • Change the value to true (Do NOT include the quotes)
  • Stop and Restart the service
