FIND seems to trigger a full resync

[amaccuish]

Grommunio-Sync has become a lot more reliable, thank you for your work!

Whilst the resyncs with this problematic user have become a lot better, they still remain. The only thing I can see is that they often occur after the iPad issues a FIND command.

I've included a more detailed log attached.

Hi @amaccuish ,

is the folder's id really kDAMailAccountAllMailboxesFolderID or did you replace its id? It is strange that this folder doesn't appear in the folder list during the FolderSync command.

Do you have multiple ActiveSync/Exchange accounts configured on your iPad? Are there another clients connected to this account (Outlook, Thunderbird, another mobile device...)?

[amaccuish]

@gromandreas hi!

on the iPad there are no other accounts configured. I did not replace this folder, and it doesn't exist in the account. It always seems to be requested when the resync happens, I'm pretty sure the log file in the other ticket has it too.

And yes, there is an iPhone and Outlook connected.

[gromandreas]

Did you try to remove the account on the device or do the full resync in order to check if that folder disappears?

[amaccuish]

The folder doesn't exist. But yes a full resync and removing and readding have been tried.

[amaccuish]

Should I try and create the folder and see what happens? Is there a way to make the folder hidden in the web ui?

I find zero documentation, either the Microsoft spec, or any other open source projects that report this folder. And the user is not trying to create such a folder name themselves. Could it be an Apple bug somehow?

[gromandreas]

Does the user use the default mail client, or is it some 3rd party app? Or does the user use some email enhancement app?

Please ask the user to provide the exact steps which cause this. I was not able to reproduce the behavior on our test iPhone, but maybe I missed something. I do not use iPhone/iPad, so having the exact steps would be helpful. Like you I also didn't find anything regarding this folder name.

It's rather a peculiarity of ios devices than a bug, however it's something grommunio-sync isn't expecting.

[amaccuish]

@gromandreas It's the default/built-in client, no other apps.

I have been trying to reproduce, I use an iPhone, but can't make it happen on my own device. As an aside, non of my searches return any results, even though I see grommunio-sync sending them. I seem to only see on-device emails, and every so often a server only email.

However, fairly reliably we can trigger it by doing a search. Here is one from just now. Apparently they're just doing a normal search. I will keep trying to see if I can reproduce, and also if it's possible to get a video/screen capture.

[gromandreas]

@amaccuish yes, it would be great if you would provide a video/screen capture. Are they doing the search directly from the inbox? Or from one of those special Mailboxes (VIP, Flagged, Unread)?
