Editing meeting invites others have sent

JAGH888 I am experiencing the same issue but would like to add more details as I am curious if my experience is unique. In the longer past, I can edit everything of an invite I received for myself, and for the calendar I have delegation access (including changing the time to the exact time I want, editing the subject line and notes section, and attaching documents). I am not 100% sure but I think it's when we moved to O365 or at some point after we moved to O365 (even though I continue to access using desktop Outlook), I can still edit the subject line, notes, and add attachments but I can no longer change the time. Then, just recently, I can no longer edit the notes and attach documents but I can still edit the subject line. I now can also change the time again but only by dragging the invite and it needs to stick with the hour or 30 min. For example, I cannot change an invite from 1- 2 pm to 1 - 1:15 pm but I can shrink it to 1 - 1:30 pm.
