Non-owners deleting conversations from Outlook on iOS
I've had a ticket open with Microsoft for a couple of weeks trying to track down why conversations in a group mailbox were mysteriously dissapearing. I was finally able to do some digging in the mailbox audit logs for one of the affected groups, and found some logs showing that the messages were being deleted by some random user, (who is not an owner of the group, just a member) using the Outlook for iOS. Search-MailboxAuditLog -Identity groupname@example.com -GroupMailbox -showdetails -startDate 2019-09-26T08:40-7 -EndDate 2019-09-26T08:57-7 ...truncated... Operation : SoftDelete OperationResult : Succeeded ClientInfoString : Client=OutlookService;Outlook-iOS/2.0; InternalLogonType : Delegated MailboxOwnerUPN : groupname@example.com LogonUserDisplayName : John Smith (User who I was logged in as) SourceItemSubjectsList : Subject of test email ...truncated... I confirmed this is happening, logged in as a non-owner in Outlook 2019 or Outlook on the Web I can't delete messages from that group, but logged in as the same user in Outlook for iOS I can delete anything. Can anyone else confirm whether they can do the same thing in their tenant? I'm worried about whether this is a bug in the iOS app itself or just with our tenant.
'Sender Restrictions' for Office 365 Groups
In our company, as part of our move from Exchange on-prem to Exchange Online, we are considering replacing our current Exchange Distribution Lists with Dynamic Office 365 Groups. Many of these top-level Exchange Distribution Lists have Sender Restrictions imposed in order to limit who can send an email to the DL membership. For example, only certain users can send an email to a Distribution List that contains several thousand staff. We are unsure as to whether Dynamic Office 365 Groups can provide similar functionality. From what I have read, any members of a Dynamic Office 365 Group have the ability to send an email to the entire group membership. There does not appear to be any way to limit this ability. Is this correct ?Group SP Site (Group image/logo Not Updating)
We have several groups we are working with, all have had a group image applied, but the Group Image doesnt seem to propogate to the connected SharePoint site (just get the colored background with two letters). Should the image populate automatically, or is this the expected behavior and SharePoint Site logos have to be manually set?
