Additional team and channel-related features and issues within Microsoft Teams for Education
Good afternoon,
I am the owner of the team. I created the announcement and posted it to multiple teams general page at the same time. I have been able to delete some announcements. However, I have several that I cannot delete. Below are two screenshots taken from the same team. One without the option to delete the other with. They were both created by me and I used the same technique for both.
