My client (nonprofit) organization is using Office365 to host their email. One, and only one, individual is having problems sharing a calendar with her supervisor. Supervisor receives "Error while preparing to send sharing message." when sending sharing message to worker. Supervisor is able to share Calendar with other staff. All staff are using Outlook 2010.
If I delete and recreate worker's email account - to try and troubleshoot this issue - will she lose email that has been sent/received in Outlook?
Any other troubleshooting suggestions? Again, this is a singular issue - not a Policy issue.
