Downloading attachments on mobile devices fails

Post by cyber035 »

Hi, today downloading attachments to everyone that have used email application on phones in my company just stopped.

Downloading attachment works from web and form Outlook, but not from any android application.

Gmail app just loops in syncing mail... and uses a lot of battery.

We use exchange protocol for connecting from phones - activesync.

When I try IMAP in app download works.

Multiple phones with different version of apps and android tested same result.

This is a Network edition Zimbra 8.6.0

There was no change in COS or any other setting in Zimbra.

We dont use any mobile policy.

I have tried restarting server, same result...

All services are up and running.

I have reboot the machine...same thing. Tried just zmcontrol restart...same thing. Deleting the account from the phone...same thing. Reindexing my mailbox...same thing. I could upgrade to 8.8...but I don't want to do that. I'm not sure if I reinstall the same version over top if that would take care of it? My guess is that one of the packages that gets updated with apt-get update might have caused this? But when I look at my dpkg logs I see it was on 1-15-2018, but I dont' think I restarted the server until just last week. So maybe that is the problem?

I have an iphone user and it works for him, so it might just be related to Android phones? Anyone else?

So I bit the bullet and tried upgrading to 8.8.6. Still can't download any type of attachment from and android device. Tried enabling the NG mobile with the same results. I'm beginning to think that maybe it is an android/google issue? Is anyone else having this issue?

I have tried it also on iPhone and same problem sooo its some thing with Zimbra.
What really annoys me is the specific nature of the problem, downloading attachment, the email works fine just not the download .... :evil:

I opened a ticket with Zimbra went through all the normal(stupid) questions. I gave them an account to test on their and and then everything started working! So I have no idea why...but it just magically started working again. Sorry I wish I had a fix for you!

We had the same problem.
Our gmail apps were updated on the phones automatically during the weekend.
This solved the problem. Yes!

That is what Zimbra support just told me. That gmail app version 7.11.26 was able to download the attachment but gmail app version 8.1.7 was not. So I guess depending on how often your phone updates you might not even see the issue.

yup it was stupid Gmail app on android, but that does not explain why other apps that I tried weren't working...
It is like all other email apps depend on some gmail app service for exchange protocol...
