MS Windows 2019, MS Exchange 2019 CU7
MS Windows and MS Exchange are installed with Russian. An attempt was made to switch the Windows interface to English, after which the MSExchangeMailboxAssistants service starts with an error and stops. I tried to return the Windows interface language back to Russian, but the service error remained.
Thanks for any help.
