Why is the conditional formatting I set up for Outlook Classic calendar disappearing?

Question

When I set up conditional formatting rules for my calendar they disappear after a short while. I have tried creating a custom view with the rules in place but they still vanish.
I love what it does but i can't be setting them up again all the time

Hi @Mary O'Connor

Thank you for posting your question in the Microsoft Q&A forum.

May I ask did it disappear when you close the app or it just disappeared after a while?

Did you perform this on your calendar or on another shared calendar?

I tested on my own and I will see the same behavior when I open another shared calendar.

After I close Outlook, the rules will disappear. And if I close and open again, the rules are back.

There must be something with the shared calendar work.

However, if I create a new view first and then use condition formatting, the rules won't go away even with shared calendar.

Did you create a custom view here? If not, please go choose Manage Views > New > Choose Day/Week/Month then apply your rules in Conditional Formatting.

Please try and let me know if this works for you.

If not, please answer my questions above so I can reproduce your case and help you better.

I look forward for your reply.

This is happening on a single account. And they are disappearing a while later, not immediately. Overnight only some disappeared!
