The latest builds of Microsoft Office for Microsoft 365 do not allow add-ins to work. This can be resolved by applying a patch to the registry — contact support for details. This error can also occur in a hosted environment when Hosted Dimensions Client tries to send an ADM document using the local copy of Outlook. Remote Desktop restrictions prevent the hosted environment from communicating with a local copy of Outlook, so this feature is not available for hosted clients. If you are in a hosted environment, use the following workaround:
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.
