Like everyone else on here, I've been struggling with M365 unified groups, after promoting it within our company.

I'm the admin, and made myself a member of 8 groups. I'm the owner of none of them. In 4 groups I have the same issue as everyone else here in regards to the categories. In the other 4 groups, the categories work fine.

I have scripted all 8 groups to dump all attribute to an Excel file, sanitized it and uploaded it to ChatGPT for analysis. It found no pattern that would explain the differences.

On prem in Outlook 2019 and 2021 categories work flawlessly across all 8.

I started off by scripting the extraction of events from Exch 2016 public folder calendars via EWS, then importing them into their respective M365 Group calendars via Graph API. This included the categories.

On all 8 group calendars the categories imported correctly, but on the problematic 4, I'm unable to edit or create categories online. In the Outlook classic app, I'm able to change anything, and it is reflected online.
