Teams Tidbit - Where is my data stored
My customer had a question about where do the messages between users get stored so that admins can perform eDiscovery and compliance. Here is what I found
- 1:1 Chat
- Messages – Are stored in the Conversation History folder in the individuals users mailbox (This would be all users in the conversation)
- Attachments – Stored in the OneDrive of the user that starts the conversation
- Channel Conversations
This article covers how to configure Teams with On-Prem Exchange environments.
Note: This would be considered a Hybrid implementation.
Make sure you read the “Known Issues” section in the article as there are some limitations to this configuration
- Groups don't appear for mailboxes moved to Office 365 When a user is moved from your on-premises Exchange organization to Office 365, groups won't appear in the left navigation pane in Outlook or Outlook on the web. To fix the issue, remove the mailbox from any groups of which it is a member, and re-add it to each group.
- New groups don't appear in the on-premises Exchange global address list (GAL) When a new group is created in Office 365, it won't appear in the on-premises GAL automatically. To fix this issue, open the Exchange Management Shell on an on-premises Exchange server and run the following command.
Update-Recipient "<group name>"
- Groups don't receive messages from on-premises users An on-premises user won't be able to send mail to an Office 365 Group when the following conditions are true:
- o The group domain is configured as an authoritative domain in your on-premises Exchange organization.
- o The group was recently created and its information hasn't been written back to your on-premises Active Directory yet.
This issue will resolve itself when Azure AD Connect performs its next synchronization between Office 365 and your on-premises organization. Azure AD Connect synchronization occurs every thirty minutes.
- On-premises users can't use links included in group message footers On-premises users can't use the View group conversations or Unsubscribe links that are included in the footer of each group message sent to them. To unsubscribe from a group, on-premises users need to contact a group administrator.
- Mail sent to a group's secondary SMTP address fails to be delivered When multiple email addresses are added to a group, only the primary SMTP address is written back to your on-premises Active Directory. If an on-premises user tries to send a message to the secondary SMTP address of a group, the message will fail to be delivered. To prevent this issue, configure only one SMTP address on each group.
- On-premises users can't become an administrator of a group On-premises users can't access the group space directly. Because of this, they can't be added as an administrator of a group.
- Delivery of external mail to a group can fail if you've enabled centralized mail flow If centralized mail flow is enabled, mail sent by an external user to a group fails to be delivered, even though the group allows mails from external senders.
- On-premises users can't send mail as a group An on-premises user who tries to send a message as an Office 365 Group will receive a permission denied error even if they're given Send As permissions on the group. Send As permissions on a group work only for Exchange Online mailbox users.
- Selecting a group from Outlook's left navigation pane doesn't open the group’s mailbox Outlook uses the AutoDiscover URL to open a group mailbox. If a group’s primary email address is in a domain that doesn't point to Office 365's AutoDiscover URL (autodiscover.outlook.com), Outlook won't be able to open the group's mailbox. To fix the issue, groups can be provisioned with a primary address in a domain that points to Office 365's AutoDiscover URL. You can configure an email address policy to add a primary email address on each group mailbox that points to Office 365's AutoDiscover URL. Check out Multi-domain support for Office 365 Groups for more details.
