Error saving event when participant has an apostrophe in login name
PaulL Seems like a bug in Microsoft functionality (APIs used behind the scene to create events).
Raise a support ticket with Microsoft directly and report this issue: Get M365 support - online support
Also, curious to know what is the error message in browser console? What is the API URL generated and shown in console?

ganeshsanap the error is generated by a batch call to web.ensureuser. The apostrophe is clearly not being escaped correctly in the request url. I've submitted a ticket to MS support.
As a test, I doubled the single apostrophe and the api call does work in that case, so should be simple enough to fix I would think.
