Allow There emails in Microsoft 365

This page is for Microsoft 365, Exchange Online, and Microsoft Defender for Office 365 administrators. It explains how to allow There emails and links when sharing messages do not arrive or are classified as junk mail.

​

Symptoms

Microsoft filtering may be involved when:

• the user does not receive the sharing email;
• the email lands in junk mail;
• There shows that the email was sent;
• SMTP logs show that Microsoft accepted the delivery;
• no explicit bounce is returned to the sender.

In this case, allow the sending domain first, then the URLs used in sharing links.

​

Items to allow

Allow the following items in your tenant security policies:

​

Allow the sending domain

1. Open the Tenant Allow/Block List in Microsoft Defender.
2. If needed, the full path is Email & collaboration > Policies & rules > Threat policies > Tenant Allow/Block List.
3. Open the Domains and addresses tab.
4. Click Add.
5. Add there.do.
6. Save.

​

Allow sharing URLs

After allowing the sending domain, add the domains used in sharing links.

1. In Tenant Allow/Block List, open the URL tab.
2. Click Add.
3. Add app.there.do/*.
4. Add share.there.do/*.
5. Save.
6. Send a new share from There to confirm delivery.
