Scheduling and managing events using Outlook.com calendar
I’m sorry the formatting and note changes are not being retained.
Could you confirm whether this is an event you created yourself or a meeting invitation created by someone else? If another person is the organizer, an update from the organizer may overwrite changes that you made to the meeting notes.
Also, if this is a recurring event, please check whether you are editing only one occurrence or the entire series. Open the event, select Edit, and choose Edit series before updating the notes. After saving, reopen another occurrence in the series to verify whether the change was applied.
As an additional check, try creating the list directly in the event editor rather than pasting it from Word, OneNote, or another application. Pasted content may contain unsupported formatting that Outlook.com converts when the event is saved.
Please let us know whether the affected item is:
- An event you created or an invitation from another organizer
- A single event or recurring series
- Stored in your main Outlook.com calendar or a shared/subscribed calendar
These details will help narrow down whether the issue is related to editing permissions, synchronization, or the event type.
