We were down from 17 admin go only 5 because of vacations, sickness and trainings. Had some issues with logins after renewing citrix certificates, mail sync to mobile devices and missing calendars in MS Teams. And that was just today.

It's been a hellish week, with customers writing more tickets than ever for the last 2 - 3 weeks. The few people that were there worked well together though, so we managed to get a lot of work done. But at that rate, people will burn out within a few months.
