Using Outlook for iOS for personal email and calendar management
InTune policies may be a contributing factor, but our organization has not engaged/deployed InTune. :-(
Agree with Evan Liu that this seemed to become an issue after an update was applied. Possibly explains why some experience the issue, and other don't, depending upon their update level, iOS version, etc?
Yet again, a simple (but much needed) feature rendered inoperable for no apparent reasoning? It seems apparent that Microsoft development has their collective heads firmly inserted into their rectums.
They just don't get it... I'm shocked, but I'm not surprised. :-/
