Use of WIKI to share approved or static text with team members - admin role for text management would be a HUGE advantage to enable adoption of TEAMS for corporate use.

Add moderation of delivery to and from O365 groups.

Please introduce a SEARCH field in the Distribution Lists (Contact Groups). It would be vital, if you would have a DL of 1000 members and you want to search for one without scrolling down the list!

When a user sends email to a moderated list, he can expand the list and bypass the moderator, since he is sending to a series of individual emails.

Also, we generate lists for classes, faculty, etc. what classes a student is taking is personal information, but anybody on campus would be able to see this. We had this issue pre-exchange 2003, but the ‘hideDLmembership’ attribute fixed it on prem, and FIM is syncing this info with O365, would be great to have it working online so we don’t have to use 3rd party mail servers.

IN order to accept emails from outside organization and having multiple tenants, option to rename email address or add another SMTP address as primary SMTP should be there. We cannot encourage users to use Office 365 Groups unless the email address is organization friendly.

The same way we can export a list of all of our distribution lists, I would like the ability to export the members of a group distribution list to a CSV or Excel file without using Power Shell.

Add a feature to filter tasks based on attributes of the tasks, such as color codes, completion status, and date ranges. This could be displayed in a manner similar to Excel pivot-table slicers or SharePoint Content filters. This filter should allow multiple selections.

In classic SharePoint Sites we have the ability to whitelist/blacklist specific domains for external sharing for a specific ite. In Office 365 Groups this ability is not available. You can whitelist/blacklist across all the Office 365 groups, but not each group that is create. We want to move over to Office 365 groups, but this is the one functionality that is blocking us from replacing classic SharePoint sites with Office 365 groups.

As of now, we have option to connect existing SharePoint team sites to new Office 365 groups. But if there is an option to connect existing SharePoint sites to existing Office 365 groups, it will be good.

Right now there is no way to archive the message thread of a Group. It would be nice to be able to convert a Group to a Shared Mailbox, or easily export contents to a PST. You can't copy messages to another folder in Outlook, all you can do is forward individual messages. When we're done with a group, we often want to archive the messages. It would be nice to be able to take all the messages and dump them into a folder in a Shared Mailbox, or even convert a group to a Shared Mailbox.

Previous to Office 365 version 1803 mailmerge executed from from a macro (using a text data source) worked properly. Now, data field delimiters from the text datasource get pulled in as part of the merged data. This seems to be related to a zoom setting, because changing the zoom setting will intermittently fix the issue. Microsoft support recommended I create this post here as the next step in getting this resolved. Reference Office 365 support ticket #12843700 for details.

e.g. I would like add Stream, youtube or URL, I can add multiple videos in one tab like a dropdown menu instead of adding a new tab.

At present the spam filter default policy is not applied to Office 365 Groups or distribution Group mailboxes. If you attempt to add a new policy and define the "Applied to" as a Group mailbox the new policy will not save. We need to be able to filter mail sent to Group mailboxes.

I need to hide Office 365 groups from Skype for Business searches. We have already hidden Office 365 groups from our GAL, and they don't show up in our on premise Skype users' searches (we're hybrid SFB, currently migrating to SFB onine), however users that are migrated to Skype for business online show all the Office 365 groups in their Skype searches.

Office 365 support has agreed this is a bug, but do not have an ETA on resolution. It would appear that this has been on a user voice request for quite some time, time for a fix!

Every time I create a new group I only have the option to click check boxes for individual users to add them to the group. I would like to be able to add groups as members. We have state, office, department groups. It would be nice to just add them as a member of a new group/team...

when set up a DDG in cloud-based environments, we can't use a wildcard as the first character as we did on-premise. For example, Sales is allowed, but Sales isn't allowed. Wildcards are valid only at the end for cloud-based environments and only at the front or back of words for on-prem environments, this is very in-user-friendly

I know that through powershell I can hide the groups from address lists but that is only after they are created. I can setup a task that runs this "Get-UnifiedGroup | Set-UnifiedGroup -HiddenFromAddressListsEnabled $true" but I would prefer if I could set it up so that when a user creates a new group that by default the -HiddenFromAddressListsEnabled is set to $true instead of $false.
