Can someone please tell me what these little blue dots and lines are on my folders?

I would guess that they are included in some type of sync if I didn't have so many sync issues to begin with. The idea that all of these folders are syncing is highly improbable with my Outlook experience. I don't know what happened, I think I clicked a function key, and none of them switch the folders back, or hide what was already hidden.

Bonus: If anyone knows how to hide the folders not--without the use of coding--, I would greatly appreciate that!

Thank you in advance!

Thanks, Moonshine! Now I can at least know what to call it! I'll do some more digging!

I have the same problem, they are not public folders, they are my folders, I can use them and see the content, but it's at least weird, and account behavior is not perfect.

Does someone find a fix for this?
