anything in the browser logs? are requests sent?
Hi, same problem here. I used the edge developertools to see what happend.
After "show pictures" I've got many request to /apps/mail/proxy. But in my browser I can't see the pictures. If I copy one oft the https://xxxx/apps/mail/proxy?src=.... links into the adressfeld from the browser, I can see the picture.
I hope it helps. You can see details from the developertolls at the attachement.
