Error screenshot :
IE browser :
Environment : Windows Server 2012 R2
We have tried all the solution given from the reference article but still IE is not able to access office 365 website.
In the Internet Properties panel, select the tab "Advanced", and in the Settings, Security section mark to activate the boxes ["Use TLS 1.1", "Use TLS 1.2"]
Added TLS 1.2 Registry - Right-click Windows button and select Run Type "regedit", and click OK Then go to "Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols", and create one key and two DWORD(32-bit) values, as the image below shows.
beside enabling TLS 1.0, 1.1 and 1.2 on the Browser I enabled TSL 1.0 for Client and server on the registry.
HKLM\System\CurrentControlSet\Control\SecurityProviders\Schannel\Protocols\TLS 1.0\Client and \Server.
The Easy Fix Tool is out dated
we cannot run below command on windows server 2012
Enable-TlsCipherSuite -Name "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384" -Position 0
unable to check Check cipher suites settings on windows server 2012
We can reproduce the behavior on lab windows server 2012 R2
Similar to below issue:

Download IIS Crypto (https://www.nartac.com/Products/IISCrypto/
Add the following Keys to the 1st and 2nd position respectively (they weren't there on 2 servers I've tested so far)
Find and move the following keys to the 3rd and 4th position respectively (they are there but not in the right order)
Make sure all of the check boxes are selected, press Apply, reboot the server.
