Our scheduled June update window was delayed to allow our development team to resolve performance issues with signature generation affecting our EU customers.

Signature generation performance

Intermittent performance issues with signature generation were observed within our EU region as a result of an influx of new customers. Our teams worked to identify the root cause of these issues and released several improvements to the signature generation process.

These changes have directly led to greatly improved performance and reliability in all Signature 365 regions, along with improvements to signature generation logging.

Outlook signature caching

As a result of the changes to signature generation, we have also introduced several changes in how the signatures are cached within Outlook itself. These changes provide increased performance, improved resilience to connectivity issues, and reduced bandwidth required for signature data updates.
