Unable to add Gmail to Outlook (Classic)

Okay this did not work either.

Gabriel, thank you for the replies. I opened an elevated command prompt and ran the officec2client.exe program as instructed. The program ran but at the end it threw the following error, I had to reinstall office. I tried a second time and it threw the same error and I had to reinstall office. Basically I cannot down grade.

I tried to add the gmail account again, the problem persists.

I noticed an option to install 32bit version and was wondering if the problem is in the 64bit build only.

Thanks again.

Daryl,

I suspect the revert issue is probably with Office 2024. It's not showing earlier builds on the release channel so we might not be able to revert Office 2024.

Also, I was working on this issue further today, and I got to root cause. I am trying to find a simpler solution.

The root cause is that when you added the Gmail account originally you missed this checkbox below. I have not found a simple way to get back to that checkbox to check it. I posted the minimal steps I could come up with below. I asked Outlook dev for suggestions, and I will report back if I get something easier.

Here is the workaround I have for now:

Workaround:

1. Close Outlook
2. Delete the google_imap entries in Credential Manager
3. Open Regedit
4. Go to path: Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Identities
5. Delete the key immediately under Identities that has the EmailAddress as your Gmail address
6. Open Outlook to the Profile with the Gmail account and click the Browser Sign In and make sure to check the box for Microsoft apps & services. Or, add your Gmail account to the profile if its not already in an Outlook Profile.
