        Microsoft has released an early version of a new Office 365 feature that would let  users permit or  block guest access to Office 365 groups.
The idea is to permit guest access to users outside an  organization so that they can communicate via groups. IT pros can run PowerShell  scripts to either block group access for users of specific domains or allow  access, according to the  announcement this week. 
It's an either/or proposition. They can either create a list that  allows guest access or create a list that blocks guest access. It's not  possible to set up both lists, according to Microsoft's  documentation.  
Once configured, it's possible to invite users to most  Office 365 groups. 
"This policy works for all workloads with Guest access  through O365 Groups such as Outlook, Teams & Planner in future,"  Microsoft's announcement explained.
This Office 365 guest access configuration capability also will  be coming to the Office Admin Portal, so it will be available for IT pros in the  more user friendly graphical user interface (GUI) form. It'll be available  "soon" in the Office Admin Portal, Microsoft's announcement  indicated.
However, it seems that the GUI version can't come soon  enough. Readers of Microsoft's announcement, such as Vasil  Michev, a Microsoft MVP, complained that they will have to check through a  long PowerShell script before using it to make a settings change. He requested making  it easier for IT pros to work with JSON functions within PowerShell scripts, plus  Microsoft should provide examples on how to run the cmdlet.
Microsoft MVP Tony  Redmond also noted in the comments that the new PowerShell script isn't signed  by Microsoft. 
"Running unverified scripts is not a habit that we  should encourage, even if the script comes from Microsoft," Redmond wrote.
It turns out that Microsoft has only provided a reference  script at this point, according to Sahil Arora of the Microsoft Tech Community.
"This is a representative script for IT admins to use  as a reference while crafting their own based on their organization  requirements," Arora wrote. "It is not a downloadable script. The  downloadable link will be provided to you in few days, which will be signed by  Microsoft."
The Azure Active Directory Module preview for Windows  PowerShell is required to use the feature. The setup, as described, seemed a bit  crazy. It consists of a series of installs and uninstalls.
