Answer 2

Hi @Johnson, Lora ，

To better understand your scenario, can you provide more details:

1. Did the problem occur suddenly?
2. Did you perform any special operations?
3. What type of account are you using?

In your case, could you confirm that the changes have been synced with Outlook on the web?

If you can find them while using Outlook on the web, you can create a new profile on your desktop and see if the issue can be solved.

Answer 3

I have this issue after switching to the 'new outlook' - all but three categories are gone and my calendar is no longer color coded.

How do I import my categories and all old event categorizations?
