Mail messages missing...

Don't know if this is a Sierra issue or not, but this is the first time it has happened, and within 2 days of upgrading to Sierra.


My main mail IMAP mail account was working fine this morning. About 49,000 messages. I glanced over at the Mail window this afternoon and it was completely blank. No messages. Title bar says "0 filtered messages".


The messages appear on my phone/ipad/webmail, but not in Apple Mail for this particular account. Other accounts are displaying fine.


I have tried rebuilding the mailbox, no change.

I have deleted the IMAP account and re-created it, it re-downloads the 49,000 messages, but doesn't display them.


The messages are still on the IMAP server, I can do an "about this account" and it shows there are 49,000 messages in the inbox.


So, now what?

Mac Pro, macOS Sierra (10.12), 12-Core 64G RAM - 1TB SSD Flash

With Mail quit....

Go to the User's Library folder. This folder is hidden by default. To unhide: Select the Finder in the Dock. Under Go in the Menu bar > hold down the Option key and you’ll see the Library.


• Go to Containers. Drag the com.apple.mail folder to the Desktop

• Go to Mail folder.

Select the V4 > MailData folder.

Delete any files in MailData with envelope in the name. (should be 3)

Open Mail. It will reindex your files.


Let me know if this resolves your issue.
