I have a client that is having a problem with outlook attachment previewer for word or excel documents. When you click on a document to do the previewer in outlook it comes up saying this file cannot be previewed because there is no previewer intstalled for it. I have checked the settings and attachment previewer is not disabled and the word and excel previewers are selected. I have tried to disable and reenable both the attachment previewer and the word and excel previewers individually. I also have it updated fully and I have done the registry key fixes that you find when you look for this problem on google. Also it is not the files themselves because if you double click the file it will open in word or excel without a problem. But the client wants the previewer to work also. Anybody have any idea of a fix for this.
