Wanted to let you know I was finally able to get it working. I went back through after deleting the entire email account (in osticket only) that was used for support emails. Recreated it and deleted the App Registration in Azure and recreated that as well.
I had deleted and recreated the App Registration several times and each time it hadn't worked in the past. However I found out what the issue was. During the steps when getting to add a client secret, I kept looking at the image in the tutorial and kept getting the "Secret ID" vs the "Value". I think that was because I tend to be a visual person and also kept associating the ID with the "Secret" one.
Regardless, I got it working and maybe as a point of reference if the tutorial is ever updated, maybe highlighting or circling the one for us visual folks could be a help, but certainly not a fault of osTicket by any means. š
I have confirmed tickets are flowing through and everything is working perfectly with staff.
