Under ‘Settings’ in OfficeAdmin, you can select a language for the general organization data. This is not the default language for all end users in the apps. The language you select here is the language for the OfficeAdmin management portal only.
Go to the menu and select ‘Settings.’
Navigate to ‘General’.
Select your organization’s language in the ‘Language’ section.
It’s not possible to change the language setting yourself on the mobile app. The mobile app adjusts the language according to the general language settings of the phone being used. This can therefore differ from the language that is set in the OfficeAdmin for the organization or for the user.
