I am not experiencing this issue on either of my Macs running macOS Tahoe 26.0.1. This is the first I have heard of this issue.

This means that when you type a name into the heading it will not give you the most recent one that you previously used. This is a known and reported bug. Here is the fix according to a search: If you have recently upgraded your Mac to macOS 26 (Tahoe), your "Previous Recipients" list may have been cleared or may not have migrated correctly. Here is how to recover or upgrade your previous recipients list, depending on whether you have a backup. If you have a Time Machine or other backup Quit the Mail and Contacts apps completely. Restore the following folder from a recent backup created before your upgrade to Tahoe: ~/Library/Containers/com.apple.corerecents.recentsd/Data/Library/Recents/ Restart your Mac. Open the Mail app. Your previous recipients list should be restored. If you do not have a backup You will need to rebuild your previous recipients list from your sent emails. Method 1: Use the 'Previous Recipients' window Open the Mail app. Go to the Window menu and select Previous Recipients. In the Previous Recipients window, you can view the names and email addresses you have recently sent mail to. Select a recipient and click Add to Contacts to add them to your address book. This will help Mail automatically fill in the address for new emails. Method 2: Manually add senders to contacts Navigate to your Sent mailbox. Select all the emails from the people you want to add to your contacts. Go to the Message menu and select Add Senders to Contacts. This will add all selected addresses to your Contacts app, which Mail uses to populate the auto-complete list. Context: macOS Tahoe and Previous Recipients macOS Tahoe (version 26) introduced major interface changes and updates, and for some users, this resulted in the previous recipients list being reset or having issues. This is not an issue with a program named "Tahoe Mail" but with the Mail app within the macOS Tahoe operating system itself. The auto-complete function relies on data stored in the ~/Library folder, which can be restored from a Time Machine backup.
