UPDATE: We are slowly phasing out usage of the Office 365 groups and converting them to full resource accounts, which will show up as secondary mailboxes in Outlook if you scroll past your own. With these full resource accounts, you'll be able to delete items and create subfolders for organization.
A common scenario: Someone calls your office's main line and, through a series of key presses, they finally land at a shared voicemail box and leave a message. Several staff members at your organization may have access to this shared voicemail box in order to check and respond to messages, but there has to be a method to this madness. We're here to help.
Navigating a shared voicemail box, otherwise known as an Office 365 group
NOTE: If you do not have access to the Outlook desktop app, please access Webmail to see the options detailed below.
You may notice that your shared voicemail box looks different than before. It still shows up as a secondary mailbox in Outlook if you scroll past your own mailbox, but it'll be nested under a "Groups" heading:
Once you click on the group mailbox, you'll see a single inbox. If you right-click on a message, you'll notice that while you now have the option to Delete messages, there is still no option to move them to another folder within the shared group mailbox (NOTE: you will not be able to retrieve deleted messages, so we don't recommend using that option for now. ADDITIONAL NOTE: Only Owners of these group mailboxes can actually delete messages - the option is available to you, but it won't actually delete unless you are an Owner). In some cases, you may wonder, "How am I going to know if someone else on my team has already responded to this message?"
The solution to your question is using the "Like" feature. Each message has a Like icon towards the top right of the message window (it looks like a thumbs up). Next to the Like icon is a dropdown arrow that will give you message actions, such as Replying to the message or Forwarding it.
After you have taken action on a message, you can simply click the Like icon.
Other staff will see a blue thumbs up on messages that have been "Liked". If they click on the message, they can click on the number next to the Like icon to see exactly which staff member Liked it (multiple staff can Like a message).
Now you can work with your fellow staff members to standardize the new workflow to your "Liking".
