Hi,

I am running into strange problem…

One of the inboxes handled by BM server, there is one with many sub folders, even into the Trash folder…

The FolderSync crashes constantly with these logs:

2020-09-04 22:07:09,034 [vert.x-eventloop-thread-3] n.b.v.c.r.i.WrappedResponse INFO - [m: POST, rid: 1372, ua: Apple-iPhone9C3/1707.80, user: [xxxx@xxxxx.com](mailto:xxxx@xxxxx.com), cmd: FolderSync, device: XXXXXXXXXX, type: iPhone, pv: 14.1, partnership: 6aeb0573-d420-4bcc-b48a-6db39e8b8a05, in.size: 13b, out.size: 13b, http.out: 200] completed in 231ms.

Sorry, it was all explained in there : [https://forge.bluemind.net/confluence/display/BM35/Problemes+de+synchronisation+mobile](https://forge.bluemind.net/confluence/display/BM35/Problemes+de+synchronisation+mobile)

It worked checking and repairing account files for me
