Some previously delayed messages are still being processed, and we are closely monitoring the remaining backlog to ensure delivery completes successfully.
identified
We are continuing to work on restoring webhook delivery for affected grants.
We will provide another update as recovery progresses.
identified
We are working to deploy a fix for the issue causing missing or delayed webhooks across providers in the US and EU regions.
We will provide another update as this work progresses.
investigating
We are continuing to investigate missing or delayed webhooks. Based on our investigation, we have expanded the scope of the issue to include all providers in both the US and EU regions.
We will provide another update as our investigation progresses.
investigating
We are investigating an issue with missing or delayed webhooks for Microsoft and Google grants in the US region.
EU region and all IMAP and EWS grants for both regions are working correctly.
[US/EU] Elevated Errors for Attachments API Requests on Microsoft Exchange (EWS) Grants
Started:
monitoring

We are continuing to monitor closely to confirm the issue remains fully resolved.
monitoring
Error rates have returned to normal levels for <tt>/attachment</tt> API requests affecting Microsoft Exchange (EWS) grants in both the US and EU regions.
We are continuing to monitor performance to confirm the issue remains fully resolved.
monitoring
<b>Mitigated</b> - We have implemented changes to address the elevated error rates affecting <tt>/attachment</tt> API requests for Microsoft Exchange (EWS) grants and are seeing recovery.
We are continuing to monitor performance to confirm full recovery across both the US and EU regions.
investigating
We are experiencing elevated error rates for the <tt>/attachment</tt> API endpoint affecting EWS grants for on-premises and hosted Microsoft Exchange providers in both the US and EU regions. Other grant types, including Microsoft Graph, Google, and IMAP, are not affected.
[US] Higher Latency for New and Updated Messages
Started:
monitoring
<b>Mitigated</b> - Sync latencies for new and updated messages in the US region have returned to normal operating levels following the infrastructure changes implemented earlier.
We have mitigated the customer impact and are continuing to monitor performance while we investigate the unusually high notification traffic that contributed to the incident.
The EU region remains unaffected.
monitoring
We have observed a large increase in notification traffic from Microsoft Graph today, which resulted in higher latencies for new and updated messages across providers in the US region.
We have made changes to our infrastructure to better handle the increased traffic, and latencies have reduced. We are continuing to monitor performance and investigate the source of the unusually high notification traffic.
The EU region is not affected.
[US] Elevated 500 Errors for Messages API Requests on IMAP Grants
Started:
monitoring
Error rates and request latency for the <tt>/messages</tt> API endpoint have returned to normal operating levels. We will continue to monitor performance to confirm the mitigation remains effective.
investigating
We are investigating elevated rates of HTTP 500 responses for the <tt>/messages</tt> API endpoint affecting IMAP grants in the US region. Some requests may fail as a result.
The issue is not affecting grants for other providers, other API endpoints, or the EU region. The overall error rate remains low. We will provide another update as our investigation progresses.
July 2026
[EU] Some Message Webhooks Missing
Started:
monitoring
We identified an issue that affected the delivery of a small percentage of message webhooks for some Nylas applications in the EU region. The issue primarily occurred between 06:00 and 11:00 UTC on July 24, 2026.
Webhook delivery has recovered, and new webhooks are being sent successfully. Nylas applications in the US region were not affected.
Customers who would like us to replay message webhooks should contact support@nylas.com as soon as possible and include their Nylas application IDs, ...
[US & EU] - Notetaker - Zoom Meetings - Degraded Join Rates
Started:
monitoring
<b>Mitigated</b> - We have deployed changes that have materially improved meeting join success rates. We are continuing to monitor performance closely and are progressively expanding the mitigation while evaluating additional improvements.
We will provide another update as this work progresses.
investigating
Our engineering teams continue to actively investigate the issue and are pursuing multiple remediation paths in parallel. The measures implemented so far have not resulted in a sustained improvement, and we remain focused on identifying an effective mitigation. We will provide another update as soon as we have meaningful progress to share.
investigating
We continue to work with our service providers and internal engineering teams to investigate the issue and evaluate potential mitigations. We will provide additional updates as our investigation progresses.
investigating
We are currently investigating degraded join rates for Notetaker on Zoom meetings (other meeting providers are not affected). We will share updates as we have more information.
Failures for some event API calls for Google grants
Started:
monitoring
We have deployed a fix and the errors are no longer occurring. We are monitoring our API traffic to ensure the errors do not appear.
investigating
We are investigating reports of some event API calls failing for Google grants. The error messages report issues with the Nylas migration API endpoints.
These errors are incorrect and our migration system was shut down long ago. We are investigating why it is triggering.
The errors appear limited to Google grants that were migrated from v2 accounts. Deleting and recreating the grant has been identified as a work around to prevent further errors.
US - Scheduled Messages API - Experiencing 500 Errors when listing scheduled messages
Started:
investigating
