Browse your groups

You'll find a Groups node in your folder list. Tap that node to see all the groups you're a member of. Here's an example from iOS.

Frequently asked questions

Where do I get the Outlook mobile app?

You can find the Outlook mobile app in your device's app store.

How do I delete a conversation?

You can't delete a conversation from the group mailbox unless you're the owner of the group or the conversation. Deleting conversations from the group mailbox is possible in Outlook 2016 and Outlook on the web. If a copy of the conversation went to your personal inbox, you can delete the copy. The owner of the group determines whether copies are delivered to member inboxes.
