Thanks to everyone who volunteered for testing the Office 365 group calendar. The TAP team will be reaching out as we are closer to being ready.
Thanks for following our suggestion to vote this up on SharePoint. It worked! SharePoint has confirmed that they have already started working on this and I’ll be getting an ETA from them after the holidays. -Suphatrajane commented
PLEASE FIX! Any ETA on this? This is a huge issue. I've spent 4+ hours investigating this issue and try to use workarounds to fix before finding this thread.
