Another update from Google.
Anyone who is still experiences issues, please get in touch with me so that we can sort out the remaining problems.
Thanks a lot for all of your support! We have had hard times to get everyone back on track, but it looks as we are slowly getting back our lives ;-)


Hi Daniel,

I hope you've been well since my last email. I wanted to give you an update regarding the recovery efforts.

The team is now at over 99% recovered, with only some few one-off complex cases remaining. Can you check your accounts, and with your customers, to verify that all data has been restored correctly?

Please let me know of any accounts that seem to have not recovered correctly so I can bring them to the attention of the team.

Thanks, and have a wonderful day!

To keep you posted:


Hi Daniel,

To give you a quick update here, the team is continuing to ramp up the recovery process, and will continue this moving into next week. Please let me know if you see any issues with this recovery process with either your own accounts or your customers'.

Thanks, and have a great weekend!

Another update from the Google engeneering team:


During the testing phase, the engineering team ran into an issue with the process management portion of the overall restoration, which was causing issues with the scalability of their solution. They've just resolved those issues, and are proceeding forward with beginning actual restores shortly.

I've asked for any updates they can provide on both an overall timeframe, as well as your specific concerns from your last email (which I haven't heard back directly on yet).

Another update from Google, they are getting closer to fixing the issue.


Hi Daniel,

I hope you've been well since my earlier message. I have an update for you regarding the Extended Properties issue.

Engineering now has code in place that they believe will recover the data for the vast majority of cases relating to this issue. They're currently testing this now, and hope to deploy it and begin to bulk restore customer data next week.

As soon as this has begun, or if there are any changes to this plan, I'll be in touch again to update you.

Thanks for your continued patience and understanding. Please let me know if you have any questions for me in the meantime.

Just received an update from Google.
They found the root cause and will hopefully fix the issue within the next weeks.


This is an automated email from Google for Work Support. Case #04906246 has been created or updated.

Here are some details about your case:

Status: New
Subject: Update regarding Contacts' Extended Properties issue
Hi Daniel,

My name is Thomas, and I'm a technical specialist with Google for Work. Sean Purcell let me know that you've been seeing some fallout from the recent issue with the extendedProperty field in Contacts. I'd be happy to let you know what happened and what's being done to address this issue.

Starting on September 19, the data in the gd:extendedProperty field was deleted from a number of Contact groups (only groups were affected, not individual contacts). This action was due to a misclassification of that data as being outdated.

The incorrect deletion issue itself has been resolved, so no further data loss should occur.

The team has been developing a method for restoring this data, which is nearing completion now. While I don't have a firm ETA for the data recovery beginning, the latest update I've seen is that they expect the process to begin in the next week or two.

The expectation is that this process will restore all lost data for these group; however, another option in the interim is to restore the Contact group data back to before September 19.

I deeply apologize for any effect this issue has had on your business. Please let me know if you have any questions regarding the issue's root cause or the forthcoming resolution.

After some more research on the weekend it turned out the Google has wiped important information from the groups in GMail that we use to share them among different users.

I'm in touch with Google to hopefully find a solution that will work without user interaction, but if you do not want to wait for that (and it is not even 100% sure that this is doable) you can try the following steps as a workaround:

* Remove all subscribers from your shared groups or simply delete all shared groups from the Shared Groups app. Select all groups and click on Remove to do so
* Make sure to click on Keep groups when prompted! This is very important as it will leave the groups untouched in GMail
* Wait for ~1 hour so that the Shared Groups app can clean up all data internally
* Re-share the groups if you have deleted them from the Shared Groups app
* Add the subscribers to the shared groups and let them accept the share
* Wait for the next sync to be completed after performing these steps
* If you end up with duplicates, please merge them in one account only. Never merge duplicates in different account within the same sync cycle!

If you give that a try, please comment on this post and share your results.
Thanks a lot for your support!

Google did it again. They have made some changes to their backend which prevent Shared Groups from syncing properly.
I've received a lot of bug reports recently, so I did a lot of testing and found the culprit:

Thanks for your understanding.

Thanks to all who helped us to get Google working on the GData issue!

Flemming Agner Jørgensen received an answer that sounds quite promising:
"Thank you for your message. My name is Jesse and I am an email specialist with Google Enterprise Support. I understand you are experiencing an issue with Floreysoft Shared Groups and have been for the past few days, and that these issues appear to be associated with the GData Contacts API. I'll be happy to assist you with this matter. 

The root cause of your behavior was indeed the GData Contacts API, as the team responsible for this product is in the process of migrating this API from one Google backend to another - your contacting us allowed us to identify a bug, which we will fix now after rolling back our transition plans. The issues you are encountering with the API should subside then within 24-48 hours. 

I hope this has been helpful. Please let me know if you have any additional questions or if I can provide any further assistance related to this matter. Thank you for your patience with this matter, and have a wonderful day."

We are experiencing issues with the Google Contacts API right now.
