Android Exchange Sync Problems: Contacts and Calendar Not Updating

Hello,

I manage a fleet of more than 1,000 Samsung Android devices using Omnissa Workspace One (AirWatch), devices are enrolled in COPE. We use Gmail, Google Calendar, and the native Samsung Contacts app in the work profile, all synchronized through an Exchange ActiveSync connector.

Since Wednesday, November 26th, we have been experiencing synchronization issues:

- Contacts and calendar events saved on Exchange disappear after some time.

- The Calendar app eventually shows an “Unauthorized Action” error and refuses to open.

- Gmail continues to sync emails normally.

The issue occurs randomly (sometimes after one hour, sometimes longer). Clearing Gmail’s app data and signing in again temporarily resolves the problem, but the issue always comes back. We've tryied uninstalling and reinstalling the app through our MDM but we can only do it user by user and we're not sure about it fixing the issue.

We have no means to "rollback" Gmail's version to an older one through our MDM, i've tryied uninstalling recent updates on one of my test phones, it's seems stable for the moment.

We noticed that Gmail received an update recently, and a couple of other fleet managers have reported the same problem since that update on Play store's comments.

Have you identified any bug or recent change in Gmail that could affect Exchange/ActiveSync synchronization?

Thank you in advance for your assistance.

Thank you @Axel_ch - any update will be good to hear so, I'm keeping my fingers crossed and hoping the issue is fixed for you and your end users 🤞

Speak soon,

Hello,

The issue seems fixed on our side. Google rolled out an update in half-december if I remember correctly and it fixed the issue.

Thanks again,
Axel.

Hi @Axel_ch and welcome to the Customer Community!

Thank you for your post - did you mean the issue started last Wednesday, on November 19th?

Have you reached out to your EMM? If so, could I ask what they said or advised?

I've passed this on to our internal team to see how we can help - I will get back to you as soon as i hear back.

If anything changes in the meantime, please let us know; the more info we have, the better 😉

Speak soon,

Emilie

Hello. I have the same problem. Exchange contacts dissapears after few minutes. I'm using http connection on unstandard port. Before September I was using https connection with own certificate, but this type of connection was disabled on android phones. It is sad for me, that I can't use any type of connection on my own risk.

Hello @Axel_ch and @marik_te - I hope you're doing well!

I've heard back from the team and they wanted to start by saying thank you for the detailed report @Axel_ch :)

Given the specific symptoms (Email syncing successfully while Calendar/Contacts fail, followed by an "Unauthorized Action" error), the team thinks this strongly indicates a regression in the Exchange ActiveSync adapter included in the latest Gmail app update.

While this is not Android Enterprise related, the Gmail team is informed of the issue and is already working on a solution - you can check the updates on this here: https://issuetracker.google.com/issues/461996029

I hope this is helpful - could you keep us updated on progress your end?

Thanks and speak soon,

Emilie

Hey Emilie,

Thank you about that information. You are writing, that the Gmail team is already working on a solution, but why are there no information about that on the shared issue on the issue tracker page?

A fix for this issue is very important for many users. I'm only an example, but I have many effected customers and they are not very happy about the current situation and also about the missing communication from Google...

Regards, Max

Hello @max_sto

I believe the Gmail team will issue a statement as soon as the solution is ready and available.

I am also sure they're doing their best to get this fixed as soon as possible - unfortunately, I won't be able to provide you with any further updates as I am not part of the Gmail team so, it's best for you to keep an eye on the issue tracker link provided.

Many thanks,

Emilie

Hello Emilie,

Do you have any update ? It seems that Google rolled out a "silent" patch without updating the app (based on what I can read on the issue tracker).

Thanks,

Axel.

Hello @Axel_ch

Unfortunately, I'm not able to provide any further updates as I am not part of the Gmail team.

However, as you mention a silent patch, does this mean the issue is fixed your end?

Thanks in advance,

Emilie

Hello,

Hard to say, we've been uninstalling/reinstalling the app for every impacted user as much times as requiered. I doesn't look like we've been getting new tickets since the 12/12.

I'm trying to get informations from my users in order to know if the issue is resolved.

Regards.
