This feature is still on the backlog.
As an international user I really hope this is fixed soon. I just had a call scheduled wrong by 12 hours due to me using the Enligsh US language UI, which forces me to use AM/PM time formats.
I suggest that you enable users to choose for them selves the time format, regardless of the UI language. Copying WIndows locale settings is nice, but please also let these settings to be set individually, as there might be scenarios where you want to keep separate settings.
We know you are patiently waiting for this feature. This feature is being implemented in stages. Fast tenant switching is currently in testing both internally and with early customers. We expect to release to the public in the Fall. I’ll post an update once it’s rolling out.
Full multi-tenant, multi-user support will be added after fast tenant switching.
Students might use this, as they might have Teams service from both their university and workplace. Currently you are forced to use one or the other browser-only.
We acknowledge the demand for this capability and are exploring the best possible solutions to enable this.
