Step 1: Go to Admin Portal, Then Azure Active Directory
To do this you will need to:
1. Click Settings within the inbox
2. Click Admin Center
3. Click show all within the admin center
4. Click Azure Active Directory
5. Then scroll down find the properties tab
Here's a recording of how to do this.
Step 2: Adjust Admin Properties
Within the admin properties section you will need to Enable Security defaults to No.
To do this click "Manage Security Defaults" then click No within the right hand slider window.
Step 3: Allow The Inbox To Use SMTP & IMAP
A. First go back to the Admin Center and select Users > Active Users
B. Select the inbox that you want to add to Warmup Inbox. By doing this a slider will come out like this:
C. Select the Mail tab within the slide and click Manage email apps
D. Make sure IMAP and Authenticated SMTP is checked.
Step 4: Wait 1 hour, then connect to Warmup Inbox
Once you've completed steps 1-3, you will be able to connect your account to Warmup Inbox! We suggest waiting for 1 hour so that the setting changes have time to propagate.
At times it takes a few hours for your newly adjusted inbox settings to propagate. If you're still getting an error within Warmup Inbox, then wait 24 hours and then try again. If you get stuck, please let us know at firstname.lastname@example.org.
