The problem occurs on all Office 365 Apps when users log into their session from powered off pc, as everyone do at the beginning of a work day.

It occurs on apps which are connected to a work account via the feature located on Windows in "Parameters>Accounts>Access work or school"

For example :

On Teams, the app will launch and open but you won't be able to change status no matter on what kind of state you're clicking and the bead that shows your status will stay white whatsoever you're trying to do. You won't be able to send/receive messages nor call someone as everyone appears disconnected.

On Outlook, the app will launch and open but you won't be able to receive/send any mails and if you do some changes (like classifying mails or creating folders) it won't be effective according to what i see on OWA on the same time.

For Excel, Word and Powerpoint, modifications and edit on files that are not located on the pc won't be savec, and in general any interaction that includes a cloud connection won't work.

For Edge, sync will be disabled and going on Office.com will ask your credentials.

For all those issues, they can be fixed at the same time for all of them by :

  1. Disconnecting the work account from this location in Windows : "Parameters>Accounts>Access work or school"
  2. Reboot the computer (Not always needed)
  3. Connecting back the work account

And voilà !

Its probably not related to Wi-fi or Ethernet connection as long as i can easily surf through the web when it occurs

It only affects O365 ecosystem

For Edge, sync will be disabled and going on Office.com will ask your credentials.

And OneDrive won't be syncing either

  2. Reboot the computer (Not always needed)

It takes me 5 to 10 minutes to do it but sometimes it happens for +10 users in the same day, it becomes quite a waste of time.

So to those people who are pure powershell and cmd mastermind :

Do you have anything shorter than my process which can give me the same result ?

Thanks to everyone who'll answer

EDIT :
It's probably not related to Proxy/Firewall as long as the same issue with exactly the same fix happened to me on a company that had no Firewall or any Proxy and on another one that had them.

It's probably not related to Wi-fi or Ethernet connection neither as long as i can easily surf through the web when it occurs

    Have you tried repairing Office 365?

    Open Settings

    Go to Apps > Apps & features.

    Find Microsoft Office 365 and select Modify.

    Choose Quick Repair or Online Repair and follow the instructions.

    Make sure your Office apps are up to date. Updates often include fixes for bugs that might cause connectivity issues.

    Ensure that your network settings, including proxy and firewall settings, are not blocking Office 365 services.
