Enable TLS 1.1 & 1.2 as Default Secure Protocols in WinHTTP

Reference Link: https://www.admin-enclave.com/en/articles/windows/402-enable-tls-1-1-and-tls-1-2-as-a-default-secure-protocols-in-winhttp.html


The setting in the graphic is INCORRECT (this setting enables TLS 1.0, 1.1, and 1.2).  The CORRECT setting is 0x00000a00 (2560), which is Hex 0200 + Hex 0800 to enable TLS 1.1 & 1.2.

OneNote Desktop Client Unable to Open Notebooks Stored on O365 SharePoint/OneDrive for Business

Issue: On a Mac where previously notebooks were opened simultaneously from multiple sources (OneDrive (Personal), OneDrive for Business, SharePoint (multiple tenants)) was reset to default and now not able to open notebooks stored in different O365 tenant subscriptions.

Root Cause: Cached ADAL credentials need to be removed.

Resolution: Perform the following steps:

  1. Go to applications -> utilities -> keychain access -> search and delete cache/identity and ADAL.
  2. During above steps, please check to have all the Office applications closed.
  3. Once all those deleted, please check the behavior again.

   

If notebook fails to open after following the preceding steps, please try to reinstall the Office package:

Accessing Website on the Actual Hosting Windows IIS (Web) Server Does Not Work

As a safeguard for reflection attacks, Microsoft has disabled loopback access to websites on the actual server that is hosting the site when attempting to access with something other than the DNS FQDN (i.e. "localhost" or "hostname of server"). However, it works when the site is accessed externally from another computer. To fix this so that you may access the site from the server, do the following:

  1. Configure the registry settings as prescribed in the following reference links:

  2. Ensure that the Internet Options settings of Internet Explorer are using the same protocols as are enabled or disabled on the server. For instance, if the server has TLS 1.0, SSL 2.0, and SSL 3.0 disabled, uncheck TLS 1.0, SSL 2.0 and SSL 3.0 in the Internet Options settings of Internet Explorer. Close the browser and then re-open. Attempt again.

Using “?” Rather Than “Where-Object” in PowerShell Query

In a PowerShell (PS) query, "?" and "where-object" are aliases. The following is an example of how to use this in a PS command.

 

The following command will list the users who are not Exchange UM enabled when ran from a Lync / Skype for Business Management Shell:

 

Get-CsUser | ? {$_.ExUmEnabled -eq "False"} | select DisplayName, ExUmEnabled | sort-object DisplayName
