Classic Outlook jumps in the message list when clicking an email or scrolling

Last Updated: September 10, 2025

ISSUE

In recent builds of Outlook, users have reported issues with the message list jumping to a different place when clicking an email or scrolling through emails. Some examples of what users have reported include:

When selecting an unread email, Outlook will automatically scroll down in the Inbox to older emails even though the original message is still selected.
The cursor jumps after deleting or changing an email to Mark as Read/Unread with the Inbox in single-line view.
While viewing the Inbox list, selecting the trash can button on an email row, the list scrolls to a random item further down in the list.
Outlook jumps down to old emails when you select an email at the top of the Inbox.
