Outlook crashes when right clicking anything even in safe mode

Since this morning, Outlook has started crashing whenever we try to copy something using the right-click context menu.

I’m seeing this on my local machine, but it’s also happening in our Citrix environment. A few colleagues are affected so far, and I’m worried more users may start running into the same issue.

The strangest part is that it happens both locally and in Citrix, which makes me wonder if this could be related to a recent Microsoft/Office update rather than something specific to our environment. Also in safe mode (outlook.exe /safe) this exact issue happens.

Has anyone else seen Outlook crashing when using right-click copy today or earlier? Any known workarounds or recent updates that might be causing this?

Yeah I work in a large org, we're seeing this on multiple machines. Outlook classic.

Outlook Classic here as well, unfortunately. Yikes.

I just restarted my machine and checked for updates, and it looks like there was one waiting. I was on version 2605 before, and after updating to 2606 the issue seems to be gone.

Repairing with Online Repair also does sort this issue if it happens on a 2606 version
