Unresolved incident: Issues purchasing Exclaimer through Microsoft Marketplace.

Jun 24, 2026

Unresolved incident: Engage Analytics emails being quarantined by Microsoft Defender.

Jun 23, 2026
Resolved - This incident has been resolved. Web-hosted images in the signature editor are now loading correctly across all regions.
A recent update to the cloud UI's Content Security Policy inadvertently restricted external image sources, causing hosted images to fail to display. The policy has been updated to allow the required image sources, and the fix has been deployed to all production regions. We're monitoring to confirm stability.
We apologize for any disruption this caused.

Jun 23, 08:01 UTC
Investigating - Exclaimer engineers are aware of an issue causing some images not to appear within the signature tester result when a test is run.
The same images appear as expected in the signature designer and in live messages.

There is no impact on email signatures, as these images are applied as expected.

Update - We will be undergoing scheduled maintenance during this time.
Jun 19, 08:30 UTC
Scheduled - Exclaimer engineers will be conducting routine maintenance on the Exclaimer portal (https://portal.exclaimer.com/) to enhance its security.

During this maintenance period, customers may experience difficulties logging into their subscriptions via the portal. However, please note that signature templates will continue to function normally throughout this time.

If you have any questions or concerns, please reach out to our great support team, who will be more than happy to help answer any questions.
