Outlook 2019 and 2021 Stop Opening Email in Different Windows After a Few Emails, and Other Functionality Issues

Daniel Lagerman 0 Reputation points

Multiple Users are reporting an issue with their version of Outlook (2019 and 2021).

The Double-Click to open emails in different windows stops after 1 or 2 emails. Using the preview view on Outlook, the users are unable to reply, forward, or open attachments. If we change the view to Compact or Single the emails open in a side window, and the reply, forward, and attachment work through the built in toolbar on the view window.

This issue only occurred after the most recent Office update, in which some of the toolbar layouts changed.

We are also receiving an error message that too many actionable messages are open, and to close other actionable message to continue. We can bypass this by clicking OK, but it pops up with most/all internal office emails.

Furthermore, one of my users attempted to click the "try new outlook" tab on their Outlook App. The Outlook App crashed, and they received a message stating the new outlook feature could not be enabled.

    The processor is still running at a much higher utilization than it should. I am going to attempt to revert my version of office to an earlier version using the office deployment tool.
