(I have at least a couple hundred filters.)Īfter a back and forth with IT at the University, they pointed me to a possible solution at this website: Fortunately, they were all messages I didn’t care about, and I think they all were targeted for deletion by my Mail filters. None of the messages showed up anywhere after clicking “OK”, either in Mail, or if I opened my email in Outlook on Safari. The error needed to be cleared before any additional emails could be downloaded from the Exchange server, and sometimes there were quite a few of them. The specified object was not found in the store., The process failed to get the correct properties. The message “” could not be moved to the mailbox “Exchange” They utilize an Exchange server, and I started getting error messages for some of my incoming emails.

I’m now retired from the University of Illinois, but still use their email service. When I updated to Catalina, I started having problems with Apple Mail on my MacBook Pro. To reiterate our advice in “ macOS 10.15 Catalina Ships, Upgrade with Caution” (7 October 2019), hold off on upgrading to Catalina for a while, particularly if you use Mail. If you moved the message to a mailbox on the IMAP server, other devices see it as deleted, and that deletion status eventually syncs back to the original Mac, where the message disappears as well.Īs Michael Tsai points out, these problems can be difficult to notice (if you’ve already updated to Catalina, run through your mail to see if it has been affected), the problems can propagate to other devices, it’s difficult to make a complete backup, and even if you have a backup, it’s hard to restore. Plus, moving messages between mailboxes on the Mac can delete message bodies, leaving only headers. In particular, he’s hearing from numerous customers that updating Mail’s data store from Mojave to Catalina sometimes says that it succeeded, when in fact, large numbers of messages turn out to be incomplete or missing entirely. Michael Tsai, the developer of the long-standing SpamSieve plug-in for Mail on the Mac, has written a blog post warning about potential Mail-related data loss when upgrading to macOS 10.15 Catalina. #1644: Explaining Mastodon and the Fediverse, HomePod Software 16.3 and tvOS 16.3, GoTo breach.#1645: AirPlay iPhone to Mac for remote video, Siri learns to restart iPhones, Apple's Q1 2023 financials.1646: Security-focused OS updates, Photos Workbench review, Mastodon client wishlist, Apple-related conferences.1647: Focus-caused notification issues, site-specific browser examples, virtualizing Windows on M-series Macs.#1648: iPhone passcode thefts, Center Cam improves webcam eye contact, APFS Uncertainty Principle.
