Hello Jim, 

We do have this on our radar for a future release. Thank you

I just upvoted this as well, we have clients that would like this feature. I know you won't be able to give an exact time frame on this, do we know if this is on the roadmap for this year?

I just switched a customer who was on M365 to SM and their first question was why is it so complicated to open an attachment when in the webmail interface. It needs to be downloaded, then opened from there. Why can't it just open directly from the server into the viewing app, whichever it may be, including a new tab in the browser (or pop-up). PDF, PNG, JPG, etc., can all be opened directly in the browser. Please add this to a near-future release, or I'll never hear the end of this one.

Hey Tony. I seem to remember an earlier version of SmarterMail did this ? Like version 12 or 14 ?

This would be nice yes !

(ot is there a method on how we can use send to mail -> with webmail ?)

Hello, 

I know it's not exactly what you're looking for, but we recently added the ability to preview attachments with OnlyOffice. We also made the attachment images larger so that they are more useful. 

Kind Regards,
