All my "On My Mac" folders have disappeared in Mac Mail
I keep a lot of emails stored in folders in Mac mail but over the weekend I noticed that all my folders were gone. The mailboxes seem to be working fine but everything I was keep in the folders and the folders themselves have disappeared.
Some of the folders still appear to exist on my hosts webmail client but not on my mac or MacBook.
I have a lot of important information in those folders and I haven't made any changes to either of my macs.
I'm running Ventura on my MacBook and I presume the same on my iMac but can't check at the moment
Can anyone help?
MacBook Air 13″, macOS 13.4
