Why are migrated Skype meeting links not clickable within Amazon WorkMail webapp?
This is a limitation of Amazon WorkMail webapp.
Skype meeting contents and links will be migrated with MigrationWiz. However, the links for Skype meetings will only be available from within Microsoft Outlook client.
To connect Microsoft Outlook client to Amazon WorkMail, refer to Connect Microsoft Outlook to Your Amazon WorkMail Account. Note: Users must create new Outlook profiles, and set up their signatures again, and reattach any PST files that were attached to their previous profile.
