The Day the Software Died

Two applications died this week: The OneNote for Windows app and legacy Outlook for Mac. Both applications stopped working. Users need to use the OneNote Win32 application that is part of Office or available from the Microsoft store if you don't have a license for Office.

If you don't have Office, you can still use OneNote but need to download it from OneNote - Download and install on Windows. (It’s free.)

If you missed the warnings from Microsoft and did not switch over to OneNote yet, no worries. All notebooks are in your OneDrive account. Open OneNote and sign in to your account and open the notebooks.

In additional those apps, Windows 10 and Exchange 2016 / 2019 also reached their “end of life” this week but were not killed off. They still work but won’t get security updates after this week.

If you purchased Consumer Extended Security Updates (ESU) option for Windows 10, you’ll get security updates for one year. This option was made available for consumers but many users (including many of my clients) were not offered the extended support option.

If you do not have ESU, Windows will continue to work but will not receive security updates. If your computer cannot upgrade to Windows 11, there is no rush to upgrade your hardware, but I expect some good sales this holiday season.

Support for Exchange Server 2016 and Exchange Server 2019 ends today | Microsoft Community Hub

End of support for legacy Outlook for Mac

Display Meeting Details in the Calendar?

A Microsoft 365 user wanted to know if it was possible to show the meeting details in the calendar view, to eliminate the need to open the meeting to check.

It depends on which Outlook. Classic Outlook will show the location and organizer in the day / week views, provided the meeting spans enough time slots. For one hour meetings, you need to use the 30-minute time scale; for 30-minute meetings, use 15-minute scale. The monthly calendar doesn't have enough room to show more than the subject and start and end times.

New Outlook and Outlook on the web will show the subject and organizer in the day and week views (depends on the time scale), but not the location.

In all versions of Outlook:

If you click on the meeting, you’ll see more information in the meeting card that pops up.

If you want to see who was invited, you’ll need to open the meeting,

If you’re viewing a shared calendar, your permissions will determine how much information you see, even in an opened meeting form.

New Office Icons

Microsoft is rolling new icons for Office applications. Microsoft 365 icons on my MacBook updated this week but my Windows desktop still has the old icons. New Outlook’s icon is not changing, and I believe classic Outlook will keep its current icon.

I haven't seen too many people who like the new icons. I’m not sure why, they aren’t that much different – just rounded corners.

The new icons will be in Microsoft 365 subscriptions and may eventually make it into Office 2024 and 2021.
