Outlook’s Groups support is improving with ways to filter Group emails and let you control which emails appear in the Inbox. Admins can manage the names given to new groups, enforcing prefix/suffix and stop specific words from appearing in Group names.
This is new in Outlook 365 for Windows v1912 build 12325.20012. ‘Insiders’ first and later for general release.
Here’s Microsoft’s description:
Advanced Group Email settings
Are you part of too many groups to count? Customize which emails or events to receive or follow in your inbox. In group settings you can select to receive all mail and events, only replies to you, replies and events sent to you, or to keep them out of your inbox altogether.
Groups Naming policy
A group naming policy enables the IT admin to standardize and manage the names of groups created by users in the organization.
The admin can require a specific prefix and suffix be added to the name for a group when it’s created, and can block specific words from being used.
This helps minimize the use of inappropriate words in group names as well as IT manage the representation of groups in their directory.
Naming Policy also helps organizations that deploy team sites to categorize them based on department. ”
