We have received multiple reports of users receiving the following error when using the Exclaimer Outlook Add-in:

'Download signature list failed - Failed to fetch'

We are investigating this further, and we will provide a further update once we know more.

This does not seem to be affecting server side signatures.

Exclaimer have confirmed that this is a known issue. They are investigating this further internally, and we will aim to provide a further update as soon as possible.

The latest update from Exclaimer is as follows:

Issue: Our metrics provider Datadog is currently unable to provide us with accurate metrics and health data. This is impacting our ability to scale the service automatically in line with load, as well as proactively identify performance problems. We have manually scaled key systems in order to ensure continued levels of service. 

Symptoms: Some services may be reporting errors or delayed response
