How To: Add Universal Mailboxes Back To Mail v14
Sometimes I wonder how often Apple really plans updates or upgrades. It also amazes me how often they shoot themselves in the virtual foot when they make huge interface changes for no apparent reason or benefit to the every day user. This is the case with the latest and greatest(?)version of Mac Mail.app v 14.0 on Apple’s new macOS 11—Big Sur.
After adding more than one mail account to Mail.app directly or via System Prefs > Internet Account, in old versions of Apple Mail you’d have the default Universal Mailboxes: Inboxes, Drafts, Sent, Junk, Trash, Archive. But in Mail v14 in Big Sur that’s not the case. For every mail account, there are now separate listings for each mail account with individual Inbox, Drafts, Trash, etc. You can no longer just click on the Universal Inbox & see all you accounts mail in one place. To restore a semblance of the old Universal Mailboxes, you now have to add them to the Favorites section of the sidebar manually.
So there you have it! The workaround to this version of Apple Mail to make it more like Apple Mail of old.
Hopefully down the line Apple comes up with an easier way to add multiple mailboxes to Favorites rather than the frustrating one at a time.
Hope that helps you out!
