2398186 - Visit check box greyed out in Outlook / Can't synchronize visits from Outlook to C4C

Symptom

You are trying to create an Visit in Outlook via synchronisation from Outlook to C4C, but the check box is greyed out.

Reproducing the Issue

- Open Outlook
- Create an appointment
- you want to click on "Visit" but the option is greyed-out

Cause

The visit check box is enabled only if the following conditions are met

User is the organizer for the appointment. This is usually the case for new appointments
The email ID of the organizer matches with the mail ID of the Outlook profile (default email ID).
The second point above is usually the culprit in such cases and this can happen due to many reasons. Some examples are given below.

In one instance, the name of an end user had changed and consequently the email ID had also changed. Though the user was able to receive emails with both old and new email IDs and all synchornization worked fine, the visit check box alone was disabled
A user may have multiple email IDs configured and chooses a calendar with a different default email ID! This is a complex case and usually not noticed with business users.

The add-in tries to resolve the primary email ID of the user and checks this against the default email ID. When this check fails, the check box is disabled.
