Hey there @ian57202 - so sorry this is happening, but I am here to help!

Firstly - You can use our Troubleshooting availability tool on your scheduling page in order to understand what's causing the conflict. I find it to be super helpful and it resolves most availability issues.  

If you’ve already done this and that’s how you figured out that there’s a “busy” event on one of your O365 calendars - ignore that part! 

It sounds like you have multiple sub-calendars and calendars on O365. Have you carefully checked each of these to ensure there is no “busy” event on any of them? 

If not - then let’s move on! Head to your Calendar Connection page and click “edit” next to “check for conflicts.” Have you also selected for “tentative” “away/out of office” and “working elsewhere” to be read as conflicts? If so - go check for events on that date/time with any of those statuses, next.

If this does not resolve your issue, try disconnecting your O365 Calendar from your Calendar Connection page and then reconnecting it. This often “resets” the connection and can clear out whatever “ghost” event might be marking you as busy.

Let me know if you are still stuck after all of that, and I’ll be here to assist! If you do need further help - including a screenshot of your O365 calendar with the sidebar in view displaying your sub-calendars as well as the date/time that you should be free but aren’t would help a lot (you can blur out all identifying info!). 

Looking forward to hearing back from you!

did all that, unfortunately hasn’t solved the issue, even removing and re-adding the account. It’s getting some sort of ghost reading from 365 that isn’t clearing out
