Newest Microsoft Office Load Problem - Outlook doesn't work with Google (authorization issues) & Need Local Data / Access

Hello,

Suddenly can't use Microsoft Office Outlook. It did an update, won't connect / authenticate with either of my email providers (Google & Earthlink). Currently can't access my contacts in Outlook or email in Outlook.

Problem as my Outlook data being held hostage in the cloud by Microsoft, unacessible. How to I get local load? Don't like Microsoft absconded all my data to their cloud, not resident on my laptop anymore. I never asked for that. Microsoft did it automatically, in background exposing me to their single point of failure from an access standpoint.

So two problems:

(1) Need Outlook to work with my Google credentials as before new MS Office load and to have my MS Outlook data resident on my laptop for the above reasons.

(2) Can't use the new MS Outlook that I have been using and how to access my data locally as currently accessible in Microsoft's Cloud for my protection surely.

Thanks,

Mark

The problem is with the New Outlook. With the new load, it prompts for the Google sign-in and never authenticates. Stuck in a forever loop "of provide Google credentials" that doesn't work. The below doesn't fix it as references Classic Outlook with a March 20, 2026 fix. This problem is with New Outlook only. It's a new Microsoft /Google problem not authenticating with Google or vice versa.

For the Google account in classic Outlook, this is a known issue that affected some Gmail and Yahoo accounts after February 26, 2026 and could also happen after a password change. Symptoms include Outlook no longer prompting for sign-in and errors such as 0x800CCC0E, 0x800CCC0F, or 0x80070057.

The service-side issue was fixed on 3/20/26, but if Outlook still is not prompting for Google sign-in, the supported workaround is to force Outlook to refresh the OAuth credentials:

Close Outlook.
Open Credential Manager from the Windows Start menu. On Windows 10, this may require opening Control Panel first.
Select Windows Credentials.
Under Generic credentials, find entries starting with MicrosoftOffice16_Data:OAUTH2.
Remove the entries for the affected Gmail account. The relevant entries include names ending with tp_google_imap_Oauth2. There can be two or four entries for each Gmail account.
Restart Outlook and sign in to the Gmail account.
If syncing does not start immediately, restart Outlook again.

If that does not fix it, there is a second workaround that removes the Outlook identity key for that account so Outlook prompts for sign-in again. This does not remove the account, but it requires editing the registry, which is risky if the wrong key is deleted.

Close Outlook.
Open Run, type regedit, and select OK.
Go to: Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Identities
Under Identities, select each subkey until the affected Gmail address is found.
Delete only the identity key that matches that Gmail address.
Restart Outlook and sign in again.

For non-Microsoft email apps and services, Microsoft states that modern authentication is required. If an app does not support modern authentication or OAuth for EAS, POP, IMAP, and SMTP, the recommended path is to use Outlook or contact that app’s support.

The request about getting data back from Microsoft’s cloud and making it local is not covered by the available material.
