How to fix error when sending a calendar invite on behalf of someone as their delegate?

Question

I manage multiple of my colleagues calendar's and am therefore a "delegate" for them in the calendar part of outlook. For some reason, a few of my colleague's calendar's have not been letting me send calendar invites - for example I will go to their calendar and create the invite, add the invitees, and then when I go to hit "Send," an error will come up that says "Something went wrong - we cannot save your update.." I have tried countless things, including having them take me off as a delegate, and then re-add me, and nothing has been able to fix this issue. Does anyone have a solution or know how I could fix this?

Hi @Kaylee Johnson ,

Welcome to our forum!

Does this issue occur in Outlook desktop client?

And have you done any specific operations before that?

For our better research, please provide a screenshot of the error. (In order to avoid privacy leakage, please remember to hide your personal information).

It's suggested that you could remove the shared mailbox or shared calendar and re-add it to check if the issue persists.
