New user can't sign in to install Microsoft 365. "Repeating redirects detected."

Question

New user can't sign in to install Microsoft 365. "Repeating redirects detected."

GraemeG-3877 60

I'm setting up a new business standard account for my church and have assigned one 365 license to one user so far. The user received the system email inviting them to Download Microsoft 365. When they select that it returns"

__Something went wrong
__Repeating redirects detected. Please try again in a few minutes.
Correlation ID: [Moderator note: Personally Identifiable Information removed]

Repeated efforts to sign in using the link in the email and directly entering the user id and password all produce the same result.

I've reviewed all the suggestions in response to similar problem request but it assumes the user is an admin, and this user is not an admin.

The user's computer was previously assigned a Microsoft 365 license from a shared family account. That sharing has been terminated.

Any suggestions for moving forward would be appreciated.

Hi @GraemeG-3877,

Thank you for providing those details. I understand the user is receiving the "Something went wrong - Repeating redirects detected" message when trying to accept the Microsoft 365 invitation and sign in.

To help narrow down the cause, could you please provide a bit more information?

Does the issue occur in multiple web browsers (for example, Edge, Chrome, Firefox), or only one browser?
Has the user tried using an InPrivate/Incognito window?
Does the same error occur on a different device, such as another computer or a mobile phone?
When the user signs in directly at https://www.office.com, do they receive the same error?

As an additional test, could the user try signing in directly to Microsoft 365 instead of using the invitation email link?

Open a browser and go to https://www.office.com.
Select Sign in.
Enter the Microsoft 365 Business account email address and password that was assigned to the license.
If sign-in is successful, look for the Install apps button in the upper-right corner.
Select Install apps > Microsoft 365 apps to download and install Office.

Please let us know whether the user can successfully sign in to Office.com, or if the same "Repeating redirects detected" error appears there as well. This will help determine whether the issue is related to the invitation link itself or to the account sign-in process in general.

Thank you again for your time and understanding. I really appreciate your patience, and I'm here to help. Looking forward to your response.

Thanks for the suggestions. The answer to your questions is yes, I tried different browsers, incognito, and different platforms. The error message varied a bit but none of the worked.

I just tried going to www.office.com, and it immediately went to a Copilot chat page. Curiously, when I click on the login icon it shows that it is logged in as the user in question. There was never any indication that a login was successful. I did find the link to Install Apps and it went to the appropriate web page.

Thank you for your help. That issue now appears to be resolved, for this user at least.

Can I ask a couple of next-step questions?

The computer already has most of the Office apps installed; it was previously under an individual family license. Do I need to reinstall the apps?

The individual family license sharing has been terminated from that account, but the OneDrive account on the computer is still showing that it is the original Personal account. Is there a way to convert that or do I need to delete it and set it up anew?

I'm happy to post those separately if that's more appropriate.

Hi @GraemeG-3877,

Thank you for the update, and I'm glad to hear that the sign-in issue appears to have been resolved.

Regarding your follow-up questions, there's no need to create a separate post unless you prefer to do so. Let's see if I can help here first.

Do the Office apps need to be reinstalled?

In many cases, a reinstall is not required. If the Office applications are already installed, the user can try:

Open an Office application such as Word or Excel.

Go to File > Account.

Check which account is currently signed in and which license is displayed.

If the old Microsoft 365 Family account is still listed, sign out of that account.

Sign in with the new Microsoft 365 Business account.

Once the user signs in with the Business account, Office should normally activate using the assigned Business Standard license.

What about the existing OneDrive Personal account?

The OneDrive Personal account and OneDrive for Business account are separate services and cannot be directly converted from one to the other.

If the user needs to start using the Business account's OneDrive storage, they can:

Open the OneDrive settings.

Unlink the existing Personal OneDrive account if it is no longer needed.

Sign in to OneDrive again using the Microsoft 365 Business account.

Choose a new sync location when prompted.

If there are files stored in the Personal OneDrive that need to be retained, I would recommend ensuring they are backed up or copied before removing or unlinking the Personal account.

Thank you again for your time and understanding.

Thank you - very helpful! I should be all set now until I try to install the new license on a PC to replace an old license from an account that the church owns but has no logon information. Thanks again.
