We are currently investigating this issue.
We are currently experiencing issues with signature imprinting and access to the Exclaimer portal across multiple regions. This is due to an ongoing outage with Microsoft Azure - https://azure.status.microsoft/en-us/status We are actively monitoring the situation and will provide further updates as they become available.
Exclaimer engineers are currently investigating a problem where signatures are being applied to messages even though a signature is already present on the most recent message. The issue does not appear to be impacting all mail at this time. We will provide more information as it becomes available.
We're having some issues with authentication and data synchronization delays for the Linear integration that will continue throughout the weekend. The engineering team is already working on a fix, which is estimated for early next week.
