"Addins" Button is missing in office online when using the wopi discovery urls

Question

until recently it was possible to add an addin in the ribbon of Microsoft Word Online via the "Addins" button. This button had disappeared first from the Test/Dogfood environment and then from the production environment.

WOPI discovery URLs

Environment Discovery URL
Production  https://onenote.officeapps.live.com/hosting/discovery
Test/Dogfood    https://ffc-onenote.officeapps.live.com/hosting/discovery

anyone has an idea why it was removed or how we can get it back?

When using office.com, the button is still available

best regards, Martin

Answer 1

Is there anyway to run a program from Edge?

Generally no, Edge used to be able to run epub files but even that feature is now removed.

Basically you can run any file type that is readable within Edge so txt or xml or htm or svg or mp4 etc.

When browsing local system in reader mode you can navigate up and down folders** local or on server and click any readable file type, however LNK files will behave in different ways.

LNK files that invoke an svg or txt or other Edge text safe readable object will open that readable bat cmd wsh ps1 file in a tab if necessary.

LNK files that call an executable such as notepad calc cmd or anything like a .hta runtime file count as not readable and are treated as requiring a security response, so will invoke an extra security step asking if you wish to download a copy.

You can download a copy of notepad.exe or cmd.exe but it will then run raw so runs outside EDGE and thus a copy of CMD.exe will simply open the console or a copy of notepad will open with a blank page. Only a copy of a stub.exe that does not need arguments would be useful.

** A zip folder normally operable in File Explorer counts as a downloadable security risk inside Edge.
