Our Exchange environment is Office 365 (Exchange Online). One of our user is unable to send calendar invite from within Outlook 2013.Error message: "Error while preparing to send share message"
I have done below troubleshooting steps, but all in vain.
1) Ensure no duplicate permission entries.
2) Account setup type - Exchange Account. Recreated outlook profile but same issue.
3) Ran outlook with cleansharing switch.
User able to successfully send share invite via OWA but not within Outlook 2013. Please advise. Thanks
