Outlook web

Empty white page, 1 line of text:
"The custom module does not recognize this error"

Refresh, all good. Exit, enter again in an hour:
"The custom module does not recognize this error"

Then why the hell is there a custom module for errors for fuck's sake? Microsoft, just let the error pass through in that case, so we can read it.

Some self-disrespecting dev wrote that with a gun to their temple.

P.S. Don't ask why I use Outlook web
