Microsoft Reference: TM1055900

Issue Status: RESOLVED

Issue Description: Users may be unable to share new files or view previously shared files within Microsoft Teams.

More info:- Users attempting to share new files may receive the errors ”Oops, something happened with the editor. Reload”.
– Users attempting to view previous Teams Chat/Channel messages that contained a shared file may receive the error ”Error encountered while rendering this message” for that specific message.

As a workaround, users are able to view/access previously uploaded files when accessing from the ”Shared” tab within all Teams clients.
Additionally, users are able to upload new files directly into Chats/Channels, or view previously uploaded Files directly from Chats/Channels when using the Teams iOS app.

Final Update: 24/04/2025 08:52:00 AM – After reverting the configuration change, Microsoft have received multiple reports from previously impacted users that the issue is no longer occurring. Additionally, monitoring telemetry shows error rates have fallen to expected levels.

Scope of impact:  Impact is specific to users who are currently configured on public preview or part of the Technology Adoption Program (TAP).

Next Steps: Microsoft are reviewing their change management processes to identify why this issue was not detected prior to deployment and reviewing their monitoring telemetry systems to better detect this type of issue sooner.
