The Bing Chat Enterprise FAQ has moved to MS Learn: https://learn.microsoft.com/bing-chat-enterprise/faq To ask questions or provide product feedback, please use the Bing Chat Enterprise discussion...
We have an Edge policy in place and I've been doing some investigation in to what settings block and unblock the Bing Chat. From what I have found, as a minimum you need to disable or set to not configured the "Block all ads on Bing Search results" setting.
Additional options to allow Bing Chat in the sidebar are:
Show Hubs Sidebar
Search in Sidebar enabled
Our Edge policy also blocks people from installing extensions unless they are approved. If you are doing this too, then you need to allow the following Sidebar application ID's to be installed:
Bing Chat - ofefcgjbeghpigppfmkologfjadafddi
Search - jbleckejnaboogigodiafflhkajdmpcl
Discover - nkbndigcebkoaejohleckhekfmcecfja
Microsoft Office 365 - gecfnmoodchdkebjjffmdcmeghkflpib
Outlook - kfihiegbjaloebkmglnjnljoljgkkchm (Optional and not required to make Bing Chat work)
OneNote Feed - gbihlnbpmfkodghomcinpblknjhneknc (Optional and not required to make Bing Chat work)
Teams Chat - piilhopgoheagglmepbmkpodfceclmab (Optional and not required to make Bing Chat work)
The above ID's can all be found by going through the output in edge://sidebar-internals
Whilst you won't be able to turn on or off BCE at an individual level, you will be able to control who has it by Group Policy or InTune policy using the above information.
I also found that users who had been getting the following come up in a loop after pressing Start Chatting.....
....clearing cache and cookies resolved this issue.
With all the above done, we can now access Bing Chat consumer but not Enterprise. Even though we have an E5 licence, it's the Original Microsoft 365 SKU. This means all our components show separately within our tenancy. Whilst there is no difference in functionality between the M365 E5 and what we have, from a ticket I have open with Microsoft, they've said that it needs to specifically say "Microsoft 365 E5" and for that option to be ticket in order for Bing Chat Enterprise to be available.
I realise it's early days with this, but Microsoft, if you say you are going to enable this for all E3 and E5 customers, but then exclude those who are on the original E5 SKU, then you need to clarify this in your comms. We can't change our licences, so I would hope that you allow the original SKU to be part of this preview.
