Unable to change or add Individual Sharing Policy

Hi everyone

 

I've got a new Exchange tenant that I'm managing and I want to disable the ability for users to share their calendars with external users as per the recommendation in Microsoft Secure Score.  However, if I go to Organization > Sharing > Individual sharing and edit the Default Sharing Policy it doesn't save and just sticks at the screen below permanently with no error:

 

 

I also tried creating a new policy but this also fails with the error below:

 

I've got the Global Admin role so I don't think it's permisson related but I've never seen this issue before and can't seem to find any documentation that mentions anything?  Any advice from anyone who has run into this before or may know what could be causing it would be gratefully received.

 

Thanks in advance.

    Sharing in Exchange Online is not enabled by default, so you shouldn't need to change anything. And creating a new policy will not affect the default configuration, so if you are trying to prevent users from sharing externally, do that instead. Under Individual sharing select the Default sharing policy > Manage domains > select the Sharing with everyone entry if present and remove it. If you also want to disable Calendar publishing, remove the Anonymous entry as well. Alternatively, instead of deleting you can Edit the entry and toggle the Share your calendar folder checkbox.

    If for some reason the process fails in the UI, use PowerShell as detailed here: https://learn.microsoft.com/en-us/exchange/sharing/sharing-policies/modify-a-sharing-policy
