Hi, you can preview some of them only like .eml files or imagines in right side panel under “Contact details” if you hover over email which contains attachments and then after preview will become visible then hover over attachment.
I apologize for not being specific, but does emclient support previews of pdf, tiff, docs, xls, etc?
No, we do not support it.
Is it going to be implemented in future versions?
At this moment we do not plan to implement it.
