The network request timed out. Please try again. [2602]

Hi Luiz Henrique Santana de Almeida,

Good day, and thank you for offering a clear description of your issue.

On iOS, all Microsoft apps share the same authentication broker. When the Microsoft Authenticator registration or token becomes corrupted, every app (Outlook, Teams, OneDrive, etc.) fails with:

“The network request timed out. Please try again. [2602]”

 There are three tasks you should do one by one to solve this problem:

1. Signing out of all Microsoft applications on your iPhone
2. Removing the Microsoft Authenticator from your registered sign-in methods after ensuring there is an alternate method registered
3. Signing in to the Microsoft Authenticator application (without QR code)

Please follow the step-by-step guide below:

Task 1: Sign out of (or remove) your account from installed Microsoft applications

Note: You must sign out of all Microsoft applications on your iPhone, including Outlook, OneDrive, Teams, OneNote, Word, Excel, PowerPoint, and others. The steps below demonstrate how to remove an account from Outlook as an example. Please repeat the same process for each Microsoft app installed on your device.

Step 1 - Open the Outlook application on your iPhone.

Step 2 - Select the icon with your initials (Or profile picture) in the top-left corner:

Step 3 - Select the settings icon in the bottom-left corner:

  Step 4 - Select your work account under Mail Accounts:

Step 5 - Scroll to the bottom of the page, and select Delete Account:

  Step 6 - Select Delete to sign-out of the application.

Step 7 - Repeat Steps 1–6 for each Microsoft application installed on your iPhone, including OneDrive, Teams, SharePoint, OneNote, Word, Excel, PowerPoint, and others.

Task 2: Remove Microsoft Authenticator from your MFA sign-in methods (** after ensuring there is an alternate method registered)**

Note: Before removing Microsoft Authenticator from your sign-in methods, make sure that at least one alternate MFA method is already registered. You can verify your registered methods in Step 3 below. If no alternate method is available, please do the following:
Step 1 - In a web browser, go to:  myaccount.microsoft.com  and sign in if prompted. Step 2 - Click on Security Info in the left navigation bar. Sign in or MFA again if prompted.

Step 3 - You will see a list of your existing MFA methods.  To add a new method, click Add sign-in method.

Step 4 - Select the method you want from the Choose a method drop down, then follow on-screen prompts to add that particular method.  Example: Choose other method(s) for Microsoft MFA.  This list will vary, depending on which methods you have already set up as seen in the list in Step 3 above.  

After ensuring there is an alternate method registered, you can continue with the following steps:

Step 1 - Open a browser and navigate to: https://myaccount.microsoft.com.

Step 2 - When Microsoft asks for "Email or phone", enter your fully qualified username of ******@yourcompanyname.com and click next.  Type in your current password on the next screen.

 Step 3 - Select Security Info from the left navigation panel:

Step 4 - Be sure there is an alternate sign-in method registered. When there is at least one alternate MFA method added, then select Delete to the right of the Microsoft Authenticator method.  

Step 5 - Open the Microsoft Authenticator application on your iPhone.

 Step 6 - Select the work profile:

Step 7 - Select the settings icon from the top-right:

Step 8 - Select Remove account:

Step 9 - Select Yes, this app only:

Task 3: Re‑register your work account in the Microsoft Authenticator app (sign in manually, not using a QR code)

Note: Because of how the Microsoft Authenticator app stores account information, it is strongly recommended to restart your iPhone or at minimum, restart the Microsoft Authenticator app before re‑registering your work account.

To restart your iPhone:

• iPhone with Home Button: Press and hold the power button, then drag the slider to power off the device.
• iPhone without Home Button: Press and hold the power button together with either the volume up or volume down button, then drag the slider to power off.
• All models: Press and hold the power button again to turn the iPhone back on.

 Step 1 - Re-open the Microsoft Authenticator, and select the + icon from the top-right:

Step 2 - Select Work or school account:

Step 3 - Select Sign in:

 Note: Choosing the "Scan QR code" option will result in a network timeout error.  

Step 4 - When asked for "Email or phone", type your ******@yourcompany.com and click Next

Note: Using any domain other than your intended work account may result in a network timeout error.

Step 5 - Complete the remaining sign-in prompts.

I hope this provides enough clarity and helps you stay inform with your current situation.
