How to reinstate access to gmail by Microsoft so I can add it back into to Outlook

Holly Oakley 20

My Samsung phone did a security update last week which caused me to have to sign in to all my emails in Outlook and I even had to change passwords. After days of struggling with a gmail address in Outlook (nothing received/sent), I removed it but now I can't reinstall it. After more days of struggling, I am sure it is because I erroneously clicked on something that deleted Microsoft access to my gmail - I even can picture the pop-up window, but now I can't figure out how to restore it's access in my gmail settings. Under third-party apps, it is no longer listed and there is no option to add it. Can anyone help? Thanks!

Based on Google’s current guidance, for a personal Gmail account, it is normal that you no longer see an “Enable IMAP” switch. The important part now is to force a fresh Google sign-in/permission prompt from Outlook on your laptop, because that is what recreates Microsoft’s access in your Google account.

On the laptop, close Outlook completely, then go to your Google Account Security page and, if shown, remove Microsoft apps & services access. After that, open Windows Credential Manager > Windows Credentials and remove the cached Google OAuth entries that start with MicrosoftOffice16_Data:OAUTH2 for that Gmail account.

Then open Outlook and add the Gmail account again so Outlook launches the Google sign-in window; when the Google permissions page appears, make sure you select Allow.

Ah!! Yes, the override is what I needed! Excellent - I have the gmail back in the line-up! However, though the folders within are listed, no emails are filed, but worse, it doesn't want to send or receive emails. It accepted a Microsoft email, but no emails from my other accounts or phone. Any tips for that? Thanks so much!

Ah - jeepers.... It just took for-e-va, but the emails have loaded into the folders and the outbox FINally cleared! I guess I just needed to "wait-a-minit..." Thank you, so much, Jeronimo!! Best to you!

Thanks a million! My local computer tech had no idea and I certainly never would have figured that out, but it is exactly what I was looking for - a "forced" renewal of allowing access!

Hi! Sorry to hear that you have troubles with this, could you please share more information? What happens when you try to connect your Gmail account in the Outlook app?

Have you looked at the process mentioned here:

I get the error message, "We weren't able to set up your Google account with IMAP. Yo umay need to make changes to your Gmail settings."

When I go to the IMAP/forwarding tab, I don't have a specific option to "enable" IMAP - I can only check "auto-expunge on..." or "auto expunge off..."

When I go to the "third party apps," I only have Samsung and a social media listed - there is no option to "add" or "restore" anything, to include Microsoft.

My Android phone Outlook is working perfectly fine - it's on my laptop that I can't reload the gmail account.
