Missing Mail Junk Mailbox
I have several email accounts and in Preferences, Mailbox Behaviors, all but one account show "Bulk" mail as a designated server option. There is a Junk mail option under On my Mac. Device: MBP, OS High Sierra (v10.13.6), Mail (v11.5).
All but one account open like this:
These are my options when I click on the tab: I've erased identifying information.
In the side bar, there is a Junk mailbox showing on the server for every account. Only one "On My Mac" account in the sidebar has a Bulk mailbox. I've tried to delete this mailbox but I get this response:
I also have an IMac running OS SL with an older mail program (v4.6) that has access to the same accounts. Every account on the Imac on the On My Mac sidebar has both a Bulk and a Trash Mailbox. It has a Trash and Junk box showing on the server. The only Junk mailbox behavior option is to store junk on the server. No accounts have this option checked. I'm not sure if this is creating a conflict.
Any insightful response is greatly appreciated. I still can't find a designated "mail" forum. Thank you.
