Engage Analytics emails being quarantined by Microsoft Defender (AU, US, EU)
Resolved - After extended monitoring, Exclaimer engineers are no longer seeing any continued instances of click-tracking links within the impacted regions being flagged by Microsoft Defender at this time.

Customers who previously disabled this feature can look to enable click-tracking analytics from within the Exclaimer Cloud portal. If you are continuing to see issues, please don't hesitate to reach out to our support team, who will be able to assist.
Jul 7, 10:41 UTC
Monitoring - Exclaimer Engineers, in cooperation with Microsoft, have been able to update their detection system to prevent our analytic links from being incorrectly identified as phishing. This change should complete replication through Microsoft 365 over the next 24 hours.

Customers who have disabled analytics within the Exclaimer Portal can look to enable the Analytics feature within the Exclaimer Portal or contact Exclaimer Support for assistance if needed.

We will provide another update tomorrow or when more information is available.
Jul 1, 10:13 UTC
Update - Our engineers are continuing to engage with Microsoft regarding this issue and escalating to highest priority. This is only affecting mail flow of customers that are using the Engagement analytics feature. Customers can disable the Analytics feature within the Exclaimer Portal manually or contact Exclaimer Support for assistance.
Jun 29, 12:11 UTC
Update - Our engineers have escalated the urgency of this with Microsoft and continue to push for updates as soon as possible.
Jun 24, 12:51 UTC
Identified - Customers in the AU and US may experience issues with emails being quarantined by Microsoft defender due to false positive phishing detection.
Our engineers are working with Microsoft to have the domain reputation cleared as soon as possible.

Issues purchasing Exclaimer through Microsoft Marketplace
Resolved - Customers are now able to purchase and set up via Microsoft marketplace again. There was a latent configuration issue within our Microsoft tenant that only became a problem recently. We are still investigating what changed Microsoft side that lead to this becoming an issue.
Jun 30, 14:53 UTC
Identified - Exclaimer is aware of an issue that may cause problems when attempting to purchase and set up Exclaimer Cloud via the Microsoft Marketplace at this time.
Starting a Trial, or purchasing through an authorized reseller or directly from Exclaimer, is working as expected.

Images not appearing in signature tests.
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.
