We recently updated our event sharing options to support sharing events to all three versions of Microsoft Outlook Calendar:
Outlook: A installed desktop application, part of the Office 365 suite.
Outlook on the web: The web client for the above, also part of Office 365.
Outlook.com: The free Outlook offering of Microsoft.
Previously, Teamup only supported the event sharing to Outlook, the installed Windows application. Now you can share events from Teamup to all three versions of Outlook.
We also updated the event sharing menu, as shown here:
event sharing, sharing options, sharing menu, working with events, share events, outlook, microsoft
So far, we supported the sharing of events only to number 1. above. The latest version now adds support for sharing events to 2. and 3.
