Hi Larry,
I hope you're having a good day.
Since you mentioned "not even calls" are coming through but "no other apps" (likely your personal/system apps like Gmail) are affected, this points toward a conflict with either the Adaptive Alert framework or the Work Profile synchronization for your Microsoft 365 environment.
You can try the following methods to resolve your issue:
1/ Turn off Notification Organizers:
Please turn off Notification Organizer in this image and config Notification categories:

1/ Turn off Adaptive features:
Disable "Adaptive Vibration:"
Navigate to Settings > Sound & vibration > Adaptive Alert Vibration.
Disable this feature entirely to test.

Disable Adaptive Battery:
To begin with, head over to the Settings menu on your device.
- Then go to Battery > Adaptive Preferences section.
- Now disable the toggle next to Adaptive Battery.

Turn off Adaptive Connectivity
- Go to Settings > Network & Internet.
- Then head to Adaptive Connectivity.
- Finally, turn off the toggle next to it

2/ Haptic Reset to re-register the notification listener
Go to Settings > Sound & vibration > Vibration & haptics.
- Toggle Use vibration & haptics OFF and then back ON.
- Restart the device.
- If the issue persists, go to into the haptics setting after the reboot and bumped the ring vibration down a notch, got vibration then on an incoming call then bumped it back to the max.
3/ Resync system clock:
Because notifications rely on a secure timestamp handshake, a slight desync in the system clock can kill push tokens.
- Go to Settings > System > Date & Time.
- Toggle "Set time automatically" and "Set time zone automatically" OFF, wait 10 seconds, and toggle them back ON.
- Reboot immediately. This forces the phone to re-register its "Push Token" with Google’s FCM (Firebase Cloud Messaging) servers.
4/ Check your Work profile:
If the missing notifications and calls are specifically from your M365/work accounts, pleas verify the Work Profile hasn't been "Paused."
- Swipe up from the bottom of your screen to the top.
- Tap the "Work" tab.
- At the bottom of your screen, toggle the Work apps switch.
When the switch is off, your work profile is paused. When the switch is on, your work profile is running.

You can also check your work profile from Quick Settings:
- Swipe down from the top of any screen and locate the work tile (briefcase icon).
You may need to swipe down again to see all your quick settings. If you don't see the work tile, you can add it if your device supports it by tapping the edit icon at the bottom of the panel.
- Tap the work tile.
When the tile is dimmed, your work profile is paused. When the tile is illuminated, your work profile is running.

5/ Contact Microsoft Support:
If the issue persists after you tried all the proposed methods, the most effective next step is reaching out to your IT admin and ask them to use their admin credentials to submit a support request through the Microsoft 365 Admin Centeron your behalf.
Microsoft also provides customer service phone numbers based on your region. Your IT admin can find the appropriate contact number here: Customer service phone numbers - Microsoft Support
This route ensures that a Microsoft support engineer can initiate a remote session to investigate backend configurations, run advanced diagnostic tools, and, if necessary, escalate the case to specialized teams with access to internal systems and logs. These backend resources are essential for resolving issues that go beyond what’s visible in the user interface.
As community moderators, we’re here to guide you, but due to privacy and security limitations, we don’t have access to the backend tools required for a full resolution. For this reason, contacting Microsoft Support via the Admin Center is the most secure and efficient way forward.
In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support
