Texts showing in outlook(PC) even though SMS sync is not selected on phone

[AC Question]

My texts are showing in my outlook inbox on PC only. On my phone, the box to sync SMS is not checked and I do not see texts on my device only my exchange account when I use my work pc or access via OWA. I have deleted phone partnerships via OWA, deleted my account on my phone and set up new and continue to have this issue. Any help would be appreciated.
Thank you
