I am exploring ways to build an editorial calendar within Teams, combining knowledge across my channels into one tab in an ideal world. I was using Asana but I am having issues with the pages appearing, and in any case not all members of my team have or desire an Asana account. I tried Planner but did not like it. Are there any other integrations others have felt work well in the interface?
Without being familiar of- or fully understand your specific use case, I think that if it is a shared calendar you want to display, you can use the group calendar (contained in the Office 365 Group on which the team is based).
The solution is then to create a page in the SharePoint area belonging to the team and in that page, embed the web part that shows the Group calendar. Then you copy the URL to the page and thereafter you can create a tab in the team, choose "Web page" and enter your copied url there.
Please note that the calendar that appears is read only. New calendar events and/or changes to existing calendars events must be done via Outlook.
