Sending accounts are used to create automatic tests and email tests via proxy email addresses. You can use the SMTP settings of most popular mailbox providers such as Gmail, Google Workspace, Outlook, and Office 365 and the SMTP settings of email service providers and delivery services that allow to use their SMTP servers in third party applications.<\/p>\n\n\n\n

Below are the steps to create a sending account with the Office 365\/Exchange SMTP settings:<\/p>\n\n\n\n

In your account, go to Inbox Insight -> Sending Accounts<\/strong>.<\/p>\n\n\n\n

Click Create Sending Account<\/strong> and enter the information:<\/p>\n\n\n\n

Sending account name:<\/strong> any name that you want to appear in the From field if your emails<\/p>\n\n\n\n

From email:<\/strong> your email address set up with Office 365.<\/p>\n\n\n\n

SMTP server:<\/strong> smtp.office365.com<\/p>\n\n\n\n

Port:<\/strong> 587<\/p>\n\n\n\n

Security protocol:<\/strong> none (works as STARTTLS)<\/p>\n\n\n\n

SMTP username:<\/strong> your email address set up with Office 365<\/p>\n\n\n\n

SMTP password:<\/strong> the App password created in your email account set up with Office 365.<\/p>\n\n\n\n

Important: To create an App password, you need Two-Step Verification on your Office 365 account to be turned On.<\/p>\n\n\n\n

Sign-in to your My Microsoft Account<\/a> homepage.<\/p>\n\n\n\n

Click the Security info<\/strong> option in the left panel.<\/p>\n\n\n\n

Click Add Method<\/strong>, then click the Drop Down, select App Password<\/strong> and click Add<\/strong>.<\/p>\n\n\n\n

Enter a unique name for this App Password (something to identify which specific application will be using this password), for example, GlockApps, and click Next<\/strong>.<\/p>\n\n\n\n

Copy the generated App Password and then click Done<\/strong>.<\/p>\n\n\n\n

Paste the App password in the SMTP Password field in the sending account settings.<\/p>\n\n\n\n

You may want to save this App password to a safe place in order you can use it again in the future. If you lose your App password, you can always create a new one following the above steps.<\/p>\n\n\n\n

Choose a folder to create tests made via this sending account in.<\/p>\n\n\n\n

Select the spam filters and email providers to be used for the tests made via this sending account.<\/p>\n\n\n\n

Click Check & Create<\/strong>.<\/p>\n\n\n\n

Common Errors and Troubleshooting Tips<\/h2>\n\n\n\n

If the SMTP settings you entered are not correct or something is blocking the connection to the SMTP server, you may see an error after saving the sending account settings. Check the list of the the most common errors and troubleshooting tips below:<\/p>\n\n\n\n

By default, users can’t create App passwords. The App passwords feature must be enabled before users can use them. To give users the ability to create app passwords, admin needs<\/strong> to complete the following steps:<\/p>\n\n\n\n

2. Browse to Conditional Access > Named locations<\/strong>.<\/p>\n\n\n\n
3. Click on “Configure MFA trusted IPs”<\/strong> in the bar across the top of the Conditional Access | Named Locations<\/strong> window.<\/p>\n\n\n\n
4. On the Multifactor authentication<\/strong> page, select the Allow users to create app passwords to sign in to non-browser apps<\/strong> option.<\/p>\n\n\n
