Sorry for the wait.
That’s interesting… does this happen with all groups and email addresses? If not, what’s the differences in between the mail addresses?
Please also update to the latest possible version as this issue may have been solved in the mean time. At least I couldn’t reproduce it on my Windows 11 Edge.
Hi there, thanks for the answer. Our version of zammad is currently on 6.0.0-1689342785.e8796845.bullseye . Yes, it happens with all groups and e-mail addresses, the two e-mail accounts I use are both smtp with basically the same settings. The error occurs in every browser I tried.
