Using classic Outlook for Windows in business environments
My solution came from changing the time zone in the highest level of configuration, the microsoft account.
I went here : https://myaccount.microsoft.com/settingsandprivacy/language and noticed that the time zone said " W. European Time", which is UTC +1.
I then changed it to "Madrid/Brussels/Amsterdam/Paris" (which is still UTC + 1 but with a different description)
Restarted everything including outlook and it worked.
My conclusion is that the time zone setting in Outlook is lower in the pecking order than the time zone setting in the MS Account which also seems to make sense from a design standpoint.
Good luck,
Paige
