Unable to send a document from Adobe Reader.

First of all make sure GroupWise is set as default mail application.

Click on Windows icon -> Settings -> Apps -> Default Apps. Here set a default Email to GroupWise MAILTO Protocol Handler.

Next open Registry Editor and go into HK_CU -> Software -> Adobe -> Adobe Reader -> DC -> Sendmail.

There is the DWORD item "bDefaultSet" which shall be set to 1 if it was set to 0.

Open now any PDF document and click on Emil icon -> Attach to Email and that shall open a new email with PDF document attached. If you have not stated GroupWise client, then it will start it and you shall login into your mailbox.
