Commenters on Tsai’s blog suggest similar problems appeared after upgrading to iOS 13. The problem may not be locked to macOS Catalina, however. After that, use File > Import Mailboxes to import specific folders into the Mail app running on Catalina. Tsai says that’s incorrect, as Mac owners can retrieve previous versions of folders packed into a Mojave-based backup of Mail’s data store. Agents state that Mail data cannot be recovered using Time Machine if customers previously created a backup on macOS Mojave. “I would not have noticed except that some of my email accounts - which, apart from my Apple ID accounts are all POP accounts so are not on any remote servers - seemed to have a surprisingly small number of messages after upgrading.”Ĭustomers flocking to Apple Support reportedly receive bad information. “I lost a lot of email messages when upgrading to Catalina,” reports one commenter. POP accounts aren’t immune from Catalina’s email deletion issue either. Mail data constantly changes too, Tsai points out, thus restoring from a backup is difficult.

Users can’t make a full backup prior to the upgrade given Mail doesn’t automatically download all messages in their entirety. Once Mac owners upgrade to Catalina, they may not see anything wrong until they access the affected mailbox or message. Eventually, the Mac will see these messages as deleted too as all devices synchronize with the server mailbox. Moreover, if they move messages to a server mailbox using one of those methods, all devices accessing that mailbox will see the messages as deleted. Users report that emails become blank - showing only headers - when using AppleScript or the drag-and-drop method. But when they open the app after the transition, messages appear incomplete or gone altogether.Īnother problem stems from moving emails from one mailbox to another.

“Nevertheless, people contact me because it’s not unreasonable to wonder if third-party software is to blame, and I also hear from people who want a second opinion because what Apple support told them didn’t make sense.”Īccording to Tsai, Mac owners appear to see a successful update to the Mail app’s data store when moving from macOS Mojave to Catalina.

“Most of the damage has occurred without my Mail plug-in even being installed,” Tsai said. Michael Tsai, vývojá doplku SpamSieve pro aplikaci Mail pro macOS, napsal na blogu, e po aktualizaci macOS Catalina se mohou uivatelm vymazat nkteré emaily.

His post is based on feedback provided by customers, though the Mail problems aren’t related to his apps. The warning arrives by way of SpamSieve plug-in developer Michael Tsai. Others claim moving emails between mailboxes results in blank messages. Many users are reporting of missing or incomplete messages after the upgrade. Mac owners who depend on the Mail app to read and manager emails may need to hold off on the macOS Catalina upgrade.
