Managing presence indicators such as Available, Busy, or Away to reflect user availability
@Indhu_Rani your article was helpful.
In my case I turned on the option to block my calendar when I was setting up the auto reply. I then returned to work a day earlier than planned. Even though I turned off the automatic reply, MS Teams appended "Out of Office" - using MS Teams calendar, I deleted the blocker that was created when I blocked my calendar, and the issue was resolved.
