Enterprise Vault Office Mail App
Hi, Yeasterday, the Enterprise Vault Office Mail App, start showing this error in the following browser Microsoft Edge(Chromium), Chrome and Firefox: [ Spoiler ] Using the Internet Explorer...
I have run into the same problem in Exchange 2016 CU16 / EV 12.4.0
Enterprise Vault requires access to https://appsforoffice.microsoft.com/lib/1.0/hosted/office.js to load the Office Mail App for EV as documented here
Apparently, there has been a change in this file on 13-Oct-20 which causes custom add-ins in OWA to break. A similar scenario has been discussed here
A fix for this has been released as KB4581424 which applies to Exchange 2016 CU17 and CU18. Need to test and verify if this fixes the problem.
This has also been documented in https://www.veritas.com/content/support/en_US/article.100048648.html
