@jon @rob I'll give it a spin again, also because sooner or later the new Outlook will come.
I never used folders, my complains are more about the UI, I find the Outlook UI more comfortable.
Can I open the mail client always in a new window? With lot of tabs and workspaces I can't find it. 🥴

@jon For me on Windows performance is more or less the same for all the above browsers. Edge is decent and do all what the average user needs. I like Vivaldi because is tweakable (I like the idea of the mail client but something on the UI doesn't work for me, maybe I'm only used with Outlook). Firefox because I use it since it was Phoenix and I'm so sorry it is dieing.

@Vivaldi Hi, I'm having issues with sync, both mobile and desktop say "Sync has failed: server error". Using Windows and Android. #vivaldi #vivaldibrowser
