Unable to connect to ExchangeOnline macOS

Brass Contributor

When attempting to connect to ExchangeOnline via powershell on macOS i get the following error. 


Exception: Connecting to remote server outlook.office365.com failed with the following

error message : error:1416F086:SSL

routines:tls_process_server_certificate:certificate verify failed


Managed to resolve my WSMan errors and then get this far. Tried in both stable and preview releases. Running macOS BigSur on M1.


Any ideas?

For PowerShell on Windows I would say "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls -bor [Net.SecurityProtocolType]::Tls11 -bor [Net.SecurityProtocolType]::Tls12" but I'm not sure if that's a thing on macOS :)
Did this make any difference?
