I can also confirm that "C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user updatetoversion=16.0.13901.20462” resolves the issues on my end also with 3 or so different clients. Reminds me of last Spring also this happened! Chris On Tue, May 11, 2021 at 2:40 PM Gregory Strike via Outages < outages@outages.org> wrote:

I do not know if this prevents the affected version from being re-installed. Or, if it prevents a fixed version from being installed once they release an update.

Hi Harris / Others

It is reported on Exchange Online in the admin centre because it affects the apps connected to exchange online.

The issue appears to be a bug in the Outlook App.

Some users have reported a solution is to roll back to the April 23rd release in the current channel:

This may need an elevated command prompt to run

"C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user updatetoversion=16.0.13901.20462

Also that OWA *should* be working.

Does mention it is "Outlook client" as where the issue is seen

"Current status: We're gathering and analyzing data in an effort to isolate the cause of impact.* Initial reports indicate that impact is specific to the Outlook client *and users with access to other protocols, such as Outlook on the web or the Outlook mobile app, can view message content in those platforms as a potential workaround."

Hi all,

Trying to track down some issues that have been reported for O365 but are impacting dedicated exchange.

We are aware of the current incidents that are posted on O365 status page, but are seeing these issues in dedicated exchange as well (no hybrid). The issues are affecting Windows (desktop client) only, not Mac EWS or dedicated OWA.

Symptoms include emails not loading, only loading the first line, flashing loaded and disappearing, only signatures displaying, etc. Throwing a stab in the dark to see if anyone is also seeing these issues on dedicated exchange, and working with engineering to determine what would be a commonality between dedicated exchange and O365.

Thanks,
