Old ISA server scheduled for replacement next month decided to (software) croak today, entire company without mail on mobile, owa or app, only Outlook (etc.) works. Everyone blaming me of course, but management didn't want to allocate the funds to replace it any sooner. FML.
Got some specialists in that tech trying to get it back up, hopefully they'll pull it off, or will restore a backup, but still ><
edit: certificate that should've been autodownloaded didn't, grabbed manually and rebooted, peaches, still §!"¤#.
