Mail Inbox disappeared

In case they are hidden:

Move the mouse pointer to the far right of Favorites.

Click the arrow button to show inboxes.

I had an inbox on my mac (MacBook Pro, ver. 11.5.1). I reactivated the Exchange Inbox. I saw a message that messages were being downloaded. I also saw that there was no longer an inbox on my Mac. Suggestions?

I lost numerous emails last night out of my inbox. They just vanished. They were old and already “read”. AND my entire VIP folder content disappeared. Folder still there but no emails left. There were a lot of emails in that folder.

most of the lost Inbox emails were VIP or Flagged emails.

very confused….

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

Open Terminal and run each of these...

sudo mdutil -E /

This basically asks for temporary super user status, which is why Terminal may ask you for your password (it may not if you’ve used a sudo command recently or are already logged in as a super user or root. The command asks the unix tool mdutil to reindex the spotlight database for everything on the computer, including external drives, mounted disk images, etc. To re-index only for a specific drive, use the /Volumes path. For example, for an external drive named “MiniMe,” the command would look like this:

sudo mdutil -i on /

Rebuilding a drive index can take a long time, so be prepared to wait whether you do it through the System Preference panel or the command line. A few minutes normally.
