Outlook plug in not syncing calendar items into Sugar

I have the Outlook plug in installed. When I add an appointment and mark it to Save, Sync and Relate it does not sync into Sugar. My emails are syncing correctly.

We have a few users with this issue.

I've uninstalled and reinstalled the plug in. We have Sugar 8.1 and I installed the plug in from the downloads section.

Any help is appreciated!
