Incident Length: 10 Day\(s\) and 3 hour\(s\)
Incident Date: 18/05/2026, 11:00 UTC - 28/05/2026, 14:05 UTC
Incident Status: Resolved
**Summary**
When composing a new email, the Exclaimer add-in was unable to acquire an authentication token, resulting in signatures not being inserted and an error message being displayed for customers using Outlook for iOS.
All other platforms, including Windows desktop, New Outlook, Mac, Web, and Android, were unaffected.
Server-side signatures continued to apply normally for customers with that configuration.
**Root Cause**
The Exclaimer Outlook Add-in uses a Microsoft authentication flow designed for Office add-ins, which is intended to authenticate users silently in the background without any user interaction. Around 18 May, this silent authentication flow stopped working on Outlook for iOS.
Following an investigation, Microsoft confirmed that a change on their side had caused the silent authentication failure, and that this change was subsequently rolled back.
**Mitigation**
On identifying where the authentication flow was failing, Exclaimer Engineers updated the Outlook Add-in \(v1.29.200\) to introduce a fallback path for when silent authentication cannot complete.
Rather than surfacing an error, the add-in now prompts the user to sign in interactively, allowing authentication to complete and the signature to be applied, improving authentication flow resilience.
This was deployed on 28 May and has been retained permanently as a resilience improvement.
**Incident Timeline**
18/05, ~11:00 UTC - Silent authentication begins failing on Outlook for iOS. Customers start experiencing signature failures on this platform
18/05, 12:51 – Exclaimer releases a new version of the Exclaimer Add-in \(v1.27.200\)
21/05, 19:01 - First report of errors from the Add-in reaches Exclaimer Engineering. Investigation begins.
22/05, 07:26 Engineering confirmed a review of the latest Add-in release had been completed; no active indicators of the issue are present based on the changes made.
10:14 – Active theory was composed on the cause of the issue; code changes are then prepared by Engineering to be released the following week to prevent potential issues over the weekend.
26/05, 10:01 UTC - First code change deployed to improve logging and extend authentication timeouts.
12:10 – Add-in v.1.28.0 is released to the production channel of the Add-in. Review of impacted systems indicates no improvement.
27/05, 13:25 UTC - v.1.29.0 is deployed to both channels to surface more detail from the authentication failure on iOS.
28/05, 07:44 UTC - Severity escalated given customer impact and duration.
10:42 – Issue confirmed to only impact iOS, with other errors likely being unrelated.
11:03 – Internal investigation is prioritized to identify the cause.
11:30 - Internal reproduction of the issue achieved for the first time, enabling rapid iteration on a fix.
13:02 - The point of failure in the authentication flow fully identified, Exclaimer Engineers also identify development of a Fix and begin prioritizing a full release.
13:50 – Add-in version \(v1.29.200\) is prepared for release, awaiting confirmation of the resolution within the preview channel before being released to the production channel.
14:05 - Updated add-in \(v1.29.200\) verified in preview and released out to production channel.
14:31 - Customer confirmation of resolution is received
29/05, 08:10 UTC - Microsoft confirms that a change on their side caused the authentication failure and that it has been rolled back. Exclaimer Engineers agree to keep the changes applied based on this information at this time.

Issue: Authentication tokens not received via email for users accessing Exclaimer Portal
Incident Length: 7 hour\(s\) and 17 minutes
Incident Date: 25/05/2026, UTC 03:12– 10:29 UTC
Incident Status: Resolved
**Summary**
Customers logging into the Exclaimer Portal using the Username and Password option were unable to receive authentication tokens for a period of time, preventing them from being able to access the portal.
The exception did not trigger alerting that engaged our key engineering team, resulting in an extended impact time.
**Root Cause**
A process-level exception had occurred and not been successfully restarted. This resulted in token codes being generated but not emailed to users when required.
**Mitigation**
A rollback of the key service that included this process resolved the issue and allowed for a backlog of token code messages that had been generated to be cleared and distributed, which then restored standard service.
Further improvements to internal escalation and alerting processes have been put into place to reduce the delay in acknowledging the issue and beginning resolution steps over public holidays.
**Incident Timeline**
03:12 - Exclaimer Engineers identify a possible issue with customers being unable to log in to the portal when using a Username and Password.
03:36 – Further testing confirms the issue is impacting the authentication code stage, where the email is never received. Other forms of authentication are working as expected.
03:18 – Status page is updated to ensure customers are aware of the issue and to advise alternative login methods.
07:37 – Exclaimer Engineering is alerted and begins to investigate the scope of the issue. Additional engineering resources are called in to investigate the cause.
08:51 – A rollback of the last set of changes made to the service is performed. Testing begins to see if the issue continues
09:04 – Exclaimer Engineers identify the issue is still ongoing despite the rollback work
09:26 - Engineers confirm that the token codes are being generated as expected, indicating the service runs as anticipated to ensure accounts are secure.
09:40 – Consistent replication of the issue is confirmed, expediting testing and remediation processes.
09:59 – Exclaimer Engineers complete further system rollbacks to address the issue.
10:19 – Engineering note that a group of token code messages are confirmed to have been sent as expected and are also received within the mailboxes of accounts.
10:29 – Log review indicates that all submitted codes are processed as expected and new requests for token codes are received by users as expected.
