- Product

- Device & OS
- macOS
- Scenario
- Collaborating on documents and waiting for @mention or comment alerts to arrive.
- Observed behavior

Ensure your Mac is connected to a stable internet connection, as synchronization and notification delays are frequently caused by poor network performance or background offline modes.
Update macOS, Office Apps, and Verify Outlook Web
Updating your operating system and Office suite often resolves known bugs related to delayed push notifications. Checking Outlook on the web helps isolate the root cause.
Delayed notifications are often a combination of outdated local client software and background syncing issues between the Mac Outlook application and Microsoft servers.
Go to the Apple menu > System Settings (or System Preferences) > General > Software Update and install any pending system updates.
Open Word or PowerPoint on your Mac. Click Help in the top menu bar, then select Check for Updates to launch the Microsoft AutoUpdate tool.
Log into outlook.office.com using your web browser. Check if the delayed comment or mention notification is already in your web inbox. If it is, the issue is with your local Outlook app syncing.
If the delay persists, open Word, click Word in the top menu, and select About Microsoft Word. Note the exact version number, and do the same for your macOS version (Apple menu > About This Mac) for further support requests.

Frequently Asked Questions
Why are my Word comment notifications suddenly delayed on Mac?
Delayed notifications are commonly caused by outdated app versions, syncing intervals set in the local Outlook app, or widespread service degradation on Microsoft's cloud servers.
Does Outlook's sync frequency affect PowerPoint mention alerts?
Yes. If you rely on email alerts for @mentions, a slow sync schedule or offline status in your local Outlook app for Mac can cause these email notifications to appear delayed.
How can I tell if the notification delay is a local Mac issue or a server issue?
Check Outlook on the web. If the notification email is already in your web inbox but not on your Mac app, it's a local syncing issue. If it is delayed on the web version as well, it is likely a server or service issue.
Where do I find the exact version of my Office apps on Mac?
Open the application (such as Word), click on the application name in the top menu bar next to the Apple logo, and select 'About Microsoft Word'. A dialog box will display the exact version number.
