IMAP Email account folders not loading into Mac Mail correctly.
Have an unusual problem, hoping it has a straight forward solution. I just Migrated from a Mac Pro to an iMac Pro. I have multiple active email accounts, and previously, in my Mail app, I would see the main inbox for each of those accounts at the top, and then all the associated subfolder / mailboxes for each of those accounts (the hierarchy of organized folders) would appear further down the sidebar, starting under "Smart Mailboxes". First account, then the subfolders, next account, subfolders and so on...
On my new machine, one of my IMAP accounts has all these subfolders listed directly under it's Inbox only. So it's become a bit of mess. If I twirl that down, it pushes all the other inboxes farther down the sidebar, which doesn't help for new, un-sorted mail.
I thought I could solve this simply by dragging a folder down the sidebar, but only creates a copy.
What is also confusing is that a non-standard IMAP account (Google based), is showing up exactly as it's supposed to in the side bar. Inbox folder at the top, and then all the related subfolders under it's mailboxes header further down the sidebar.
Hopefully this makes sense, but looking to see if there is anything that can be done to resolve??
Thanks!
