  • Hi Mahfuz,

    If your Exchange server is working fine and still getting this error message, Kindly check and verify Microsoft recommended Exchange file,folder and process are excluded in  Antivirus.

  • Hi Mahfuz.rupok,

    Which CU are you using now?

    Please try to enble TLS 1.2 for .Net 4.x:

    Go to Registry and add two dwords in the following location:

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
    "SystemDefaultTlsVersions"=dword:00000001
    [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
    "SystemDefaultTlsVersions"=dword:00000001

    The SystemDefaultTlsVersions registry value defines which security protocol version defaults will be used by .NET Framework 4.x. If the value is set to 1, then .NET Framework 4.x will inherit its defaults from the Windows Schannel DisabledByDefault registry values. If the value is undefined, it will behave as if the value is set to 0. By configuring .NET Framework 4.x to inherit its values from Schannel we gain the ability to use the latest versions of TLS supported by the OS, including TLS 1.2.

    For detailed information, see this doc:https://techcommunity.microsoft.com/t5/exchange-team-blog/exchange-server-tls-guidance-part-2-enabling-tls-1-2-and/ba-p/607761
