Troubleshooting email delivery issues

If users aren’t receiving email notifications (e.g., for absence requests, calendar invites, or activation links), this guide will help identify potential issues and provide solutions.

​

Common causes of undelivered emails

1. Outlook calendar synchronization is enabled: This bypasses email invitations by directly updating users’ calendars.
2. Invitation emails were not sent: The invitation setting might have been disabled.
3. User accounts are inactive: Notifications are not sent to inactive accounts.
4. Email filters or spam rules are blocking absentify notifications: Emails might be routed to spam or blocked by IT policies.
5. Delivery errors are logged in email history: Check absentify’s email history for specific issues.

​

Checking email history in absentify

absentify provides an Email History tab to help diagnose delivery issues.

​

Steps to check email history:

1. Navigate to Settings > Users.
2. Select the user experiencing the issue and open their profile.
3. Click on the Email History tab.

Here, you’ll see:

• Status: Sent, Bounced, or Failed.
• Timestamp: When the email was sent.
• Reason for failure: For example, an invalid email address or a blocked domain.

Address any issues based on the logged reason (e.g., update the email address or whitelist absentify’s domain).

​

Outlook calendar synchronization

When Outlook calendar synchronization is enabled, absences are automatically added to users’ calendars, skipping email invitations.

​

How to check and adjust:

1. Navigate to Settings > Microsoft.
2. Disable the Outlook calendar synchronization toggle if you prefer email invitations.

​

Invitation emails not sent

If users didn’t receive their invitation emails, check the Send invitation mail setting.

​

Steps to resolve:

1. Manually invite the user:

   • Share this link: https://app.absentify.com/login.
   • After logging in, they can select Join an existing company.

2. Enable automatic invites for future users:

   • Go to Settings.
   • Ensure the Send invitation mail toggle is active.

​

Account not activated

Users must activate their accounts by logging into absentify at least once to start receiving notifications.

​

What to check:

• Confirm if the user has logged in.
• If not, resend the invitation or provide the login link.

For more details, refer to our guide on activating users.

​

Email filters or rules blocking absentify notifications

If emails still aren’t arriving, they may be blocked by company-wide email rules or spam filters.
