When it comes to collaboration, Outlook is still the most in common tool. It’s not only an e-mail client, it allows you also managing your appointments, tasks etc.
Especially the manager-delegate scenario, Outlook is THE tool to be used. But even we have great features, supporting our daily work and many scenarios, there are always limits. And these limits can cause a lot of trouble.
