This error has two possible causes: Microsoft 365 builds: Recent builds of Microsoft Office for Microsoft 365 may prevent add-ins from working. A registry patch can resolve this — contact support for details. Hosted environment: Hosted Dimensions clients cannot use a local copy of Outlook to send ADM documents. Remote Desktop restrictions prevent the hosted environment from communicating with local applications. Use the workaround below instead:
In Dimensions, open the required document.
In the Document Management window, click Print.
If no PDF printer is selected, use the Name drop-down to select one. Several free PDF printers are available online if needed.
In the Save As window, select a location to save the document.
Use your local email client, attach the document, and send to the desired customer or supplier.
