This just happened a month or so ago at my place of employment… except there were no invites. No meetings. It went more like

9am: Hey, where did my chat with so and so go? Friggin teams…

11am: Now the other one is missing? Wtf?

1pm: Outside TM: Hey… dumb question, but do you have as many people on your team as you did yesterday?

Email Invite for 1:30PM has entered the chat
