Users may experience delays when sending or receiving Exchange Online email messages
Service Degradation

More info: This issue specifically impacts users who are on Simple Mail Transfer Protocol (SMTP) connection methods, which include Outlook on the web, the Outlook desktop clients, and the mobile apps.

Current status: The service provider's investigation has further identified that exceptions may be occurring as their mail transport service is sending an unexpectedly large amount of requests to downstream components in the mail routing code path. They're investigating recent changes to confirm this theory and determine next steps for remediation. https://status.dal.ca/service.php?Service=39 2026-01-30 10:28:14 TEAMS NOTICE
Some users may see stale profile pictures or profile information for other users within Teams
Service Degradation

More info: This issue strictly affects some users attempting to view the profile picture or information of other users who modified either field after Tuesday, January 27, 2026, at 9:00 AM UTC.

Current status: The service provider has identified that a code regression contained in a recent update to a portion of the Teams service infrastructure is causing the impact. They're preparing to revert the offending update to remediate the issue. https://status.dal.ca/service.php?Service=39 2026-01-29 09:35:09 TEAMS NOTICE
Teams meeting participants may not be granted permissions to meeting notes added after meeting creation
Service Degradation

More info: When users add meeting notes from the Teams Calendar to a meeting that has already been created, the meeting participants may not be granted permissions to view the notes, while the user that added the notes may be able to access them as expected.
Impact may occur when the admins have enabled the Specific People Link (PSL) policy.

Current status: The service provider has reproduced the impact using their testing environment and identified a latent code misconfiguration that's causing the impact. They're developing a code fix to correct the misconfiguration and will provide a timeline for the completion of the fix as one becomes available. https://status.dal.ca/service.php?Service=9 2026-01-29 08:59:49 Service Restored

Service Degradation

More info: The issue primarily occurs on Teams Meeting Room devices using both Windows and Android but is not limited to these devices.
Affected users may be able to resolve the quality issues by leaving and rejoining the meeting.

Current status: The service provider has identified an issue which can lead to degraded video quality during calls for some users which was introduced in the latest Teams server deployment. They've developed and begun deploying a mitigation strategy which has proven successful at remediating the impact during their testing, and a small number of users should already be experiencing relief.

Some users may be unable to open some SharePoint Online list links through Teams on iOS and receive an error
Service Degradation

More info: Specifically, users attempting to access SharePoint lists through Teams on iOS may receive an access permissions error stating: "Permission required - You do not have permission to open this file."

While the service provider is focused on remediation, users on iOS can access the affected pages and list links by manually copying the impacted URLs from the Teams chat to open them elsewhere. Additionally, users with access to alternative Teams access methods such as the Teams desktop client and web app can use these to avoid impact.

Current status: The service provider has determined that a latent code issue is affecting the request flow leveraged for SharePoint Online list link access within Teams on iOS, resulting in impact. They're proceeding with further analysis to determine their options for remediation.

Scope of impact: Any users attempting to access SharePoint lists through links shared on Teams while on iOS may be impacted. https://status.dal.ca/service.php?Service=39 2026-01-15 10:28:00 TEAMS NOTICE

Service Degradation

More info: This issue strictly impacts users with the Dynamic Delivery policy enabled.
The service provider has temporarily disabled Dynamic Delivery while they work to resolve this issue. This action may result in potential delays of up to fifteen minutes for users to receive email messages with attachments. The length of the delay will depend on the attachments associated with the email message.
Additionally, some users see a "Safe Attachments Scan in Progress" message upon opening an encrypted inbound email message.

Current status: While the service provider reviews HTTP Archive format (HAR) network trace logs to isolate the underlying cause of impact, they've disabled Dynamic Delivery to avoid new email messages from becoming impacted. In parallel, they're in the process of validating a fix to allow delivered S/MIME encrypted email messages to be viewed as expected.
