Office 365 apps are closing randomly on MacOS
Hi,
is anyone currently experiencing issues with all MS Office 365 apps (Outlook, Excel, Powerpoint, OneNote, Word) in the way that they close all at once, randomly, and you are probably losing work due to the unexpected shutdown.
I got a new MacBook Pro with M3 Max with Sonoma 14.5 recently, and after using it for a few hours, it seems that sporadically, all O365 apps mentioned above that are open at the moment are closing all at once, randomly, without any error message, without any prior notice or any user interaction. ALL other applications except Office are working fine, also OneDrive and MS Teams stay open without any issues. After using the MacBook for a few days, it seems that it's maybe more likely to happen when the Mac is going to standby / lid closed and is woken up afterwards?
Steps I already tried without any change of the behavior, each also including a complete reboot of the machine, in the following order.
- Updating Office with the MS AutoUpdater application
- Simple uninstall of MS Office applications
- Reinstallation by using a clean new O365 download
- Manual uninstallation using https://support.microsoft.com/en-us/office/uninstall-office-for-mac-eefa1199-5b58-43af-8a3d-b73dc1a8cae3
- Clean reinstallation after complete manual uninstallation
- After uninstalling again, I tried to install it manually with deselection of the MS Defender which is included in the O365 installer package (Defender is already installed by default on the Mac).
- Renaming the MacBooks hostname from XXX-MBP-ABC123DEF to XXXMBPABC123DEF and renaming the SSD name from Macintosh HD to MacintoshHD.
- Complete wipe of the MacBook with my IT department and reinstall / setup of the machine, followed by starting auto updater and updating everything to the latest version.
None of these steps is working, and Office keeps shutting down / crashing without any prior notice at random times, most likely after a sleep. It is enough to just open up some office applications and leave the Mac alone, after return you will find the Mac with all office applications closed (except Teams and Onedrive as mentioned above).
Furthermore, I already set the network availability during sleep within my energy saving settings:
- Wake for network access from "Only on Power adapter" to "Always"
Does anyone have any further ideas for analysis or a solution?
On my private MBP with M1 Pro and Sonoma 14.5 there are no issues at all.
Thank you!!!
Michael1240, the fix is done by there side on the back end of Intune since it is Intune that is causing the issue with the Microsoft 365 apps for MacOS package. I changed my assignment on that from Required to Available for Enrolled Devices and it stopped everything from crashing. I will put it back once it is confirmed it is resolved. Now in my portal it is showing my machine, another machine I enrolled, and 2 other machines that are showing pending Install status and it was not like that yesterday afternoon when I made the change. They were all showing as installed. I hope they fix this, but it won't be done until 2PM EST today. Fingers are crossed

We are experiencing the same issue with two MacBook Air 2019 running latest Sonoma update ( was also crashing running the latest Ventura OS for one of the users before he updated to Sonoma.)
So no this is not only affecting newer Mac models.
For us this issue started maybe mid last week.
I tought we we're alone on having this weird issue, since there wasen't really any forums posts or know issues adressed until i found this post.
- Same issue here with a couple new devices. All are MacBook Air (15-inch, M3, 2024). Reinstalls of just the apps and the OS have been done and still the problem persists.
Michael1240 Same issue here.
MBP 2024 M3 Max
48 GB Memory
Watchguard Pro Virus/Threats
This machine was given to me new as I started a new position in mid-May. Has been consistent since I got it.
- Would also be interesting what the common factors are.
MBP 2023
M3 Max
Sonoma 14.5
FileVault Encryption enforced by policy?
MS Defender enforced by policy?
I will urge our IT dept to also open a support ticket at Microsoft as I am finished with trying things without proper error logging available.- Exact same here...
As we had two machines next to each other we noticed that on one machine Excel closed while on the other Teams wanted to sign in...
This happened twice and I don't know, if this is related to our problem...
- MBP 2024
M3 Pro
Sonoma 14.5
No MS Defender - SentinelOne

Copy the exact same "experience"!
No crash log is generated. Apps close at the same time (had Excel and OneNote close at the same time). Teams stays open...Besides randomly closing the apps are also lagging from time to time. No scrolling or data entry possible for like 20s, then jumps back to life, catches up with all the interaction and sometimes freezes again...
- Does anyone else run the Zoom app and plugin for outlook?
- In terms of plugins I can say that we don’t have any except Teams plugin and I have a license of Copilot.
- PSH, are you running an M3 chip?

Michael1240 am watching this as we are experiencing exactly the same on a new Mac. We are going to open a support ticket with MS.
