I upgraded 2 endpoints from Office 2010 to Office 2016 on the morning of 2/13/21. After the installations completed, I used the Central's Updates | Windows to select the 2 machines and then Check for Updates (after setting the machines to Download Updates for Windows and Other Microsoft software). After the check seemed to complete, there were no updates selectable for Office 2016 on these two units. I checked back a couple times over the weekend (the units were online the entire time), but still no updates were available. Monday morning (2/15/21) when I checked again, then there were something like 175 updates available for these two machines, the vast majority of which were for Office 2016. The updates seemingly installed fine at that point. Has anyone else run into a similar delay in update availability for Other Microsoft (or Windows direct) updates?
