Please provide details, this issues on which version of Outlook.

check Gmail settings, confirm IMAP / POP access enabled on Gmail account.

confirm Gamil MFA enabled.

remove current Gmail settings from Outlook once, then setup Gmail account as Google account on outlook.

this is my 4th attempt to do so; on the 2 posts i tried with details the robot deleted the posts for reasons i don't know...

it's outlook 2021 connecting to standard gmail via imap.

works fine for other email accounts - this particular account was working fine too for the last decade but as of 4 days ago stopped syncing.

the sending side is ok as when adding the account to the mail profile the test email is sent fine as verified by checking using gmail web ui.

with logging enabled i can find a log that contains:

PARSE ERROR: hr=2148322522

for that account and no more after it previously stated login to server ok.

Please do not make multiple post.

Did you check Google account security settings?

Device which has issues register as your device under Google Account security settings?

Did you check recent security activity for device / app not blocked?

Also try run Outlook under office safe mode if issue replicated under office safe mode

thanks for the quick responses.

i did not do multiple posts (multiple threads?) - on submission the forum robot told me the post was automatically deleted for some unspecified violation.

running outlook in safe mode did nothing other than prompt me for the email profile to use and turned off logging - the afflicted account still does not sync. The other accounts in the profile, also gmail imap, sync fine.

i knocked up a rude console app using mailkit nuget .NET package and i can access all inbox messages for the account fine. i haven't tried other folders as i don't use them other than sent items.

p.s. when i say it was working fine for decades before, clearly i wasn't using 2021. I upgraded most recently from 2016 thinking that google had finally pulled the plug on the older versions.

that said, when the integration fails, outlook uses iexplore to render the page asking for credentials which seems odd as it is not the default browser...

Answer 1

Hi @Anthony McAlister

Welcome to our forum!

To better assist you to solve the problem, could you please describe more about the error?

Does the error occur on the Outlook desktop client? To further confirm if the issue is more related to Outlook desktop client, if possible, please log in to your web mail and do the same test to check if the error persists.
And what is the version of your Outlook? It is recommended that you please check the Outlook client version (File>Office Account>Product Information) and try to upgrade to the latest version to see if the problem is resolved.
Would you please provide a screenshot of the error? (Note: In order to avoid privacy leakage, please remember to hide your personal information.）

In addition, you may refer to the article: Fix problems connecting your Google account to the Microsoft Cloud - Microsoft Support to diagnose and fix the issue.

If all above do not work, considering data file corruption, it is proposed that you create a new profile, re-add your account to the new profile and check if the same error still occurs.

Hope it helps!

Answer 2

Hi, in response:

Yes... Using outlook web is not applicable as i only want to use outlook desktop to provide me with a nice front end to manage offline emails. I can use a web browser fine to access the emails - the one that gmail provides... This seems to be a client side issue with outlook as i can access the gmail imap servers fine via my own console app using MailKit Nuget package and using the same imap settings (server address, user account details etc). However, i would rather not have to spend the time writing my own version of outlook. POP3 works too from outlook, but the data there is really old as i moved to IMAP some years ago. This issue was first noticed on outlook 2015. I upgraded to 2021 to eliminate just that possibility that the issue had since been fixed. No such luck. Exactly the same outcome.
I don't think there is a benefit to a screenshot as it is purely a popup asking for login details (rendered by iexplore.exe, not the default web browser, or even the expected modal dialog) - This in my experience as a programmer is indicative of a uncaught logic process bug and the function failure return code is assumed by the caller to be the most common one that function can encounter (login failure). I note that the trace output i would use in my own code to diagnose just such a problem, i can not find in a log file, or find how to make outlook generate it.

hi, it really is a problem with outlook classic.

There is nothing wrong with how i set it up as it was working fine for 10 years until 1st week of August just gone.

For lack of a working MS product i have installed Thunderbird and that connects to that account 100% ok. Even does it via 2FA.... It seems to use SQLLite so i feel right at home...
