Occasional Visitor

I am wicked sick and no longer able to send Outlook meeting invites from the desktop app or Office Online. When I send out a meeting invite, I receive the message "unexpected data was encountered. Mail could not be sent. Error code: -17997." When I log into Office Online, the meeting invite is there, but it says "You haven't sent this meeting invitation yet." But then I can't even get it to send from online, nor create a new meeting and send it.

Does this happen only with meeting invites? I would suggest opening a support case as there's not much information available to troubleshoot this.
