[horde] Previous request processing for synckey

[grupo correo]

Hi all.

We have testing the new version of horde (Horde Groupware 5.2.5, Horde
5.2.4, IMP 6.2.7, Kronolith 4.2.5, Turba 4.2.5, Ingo 3.2.4, Mnemo 4.2.5,
and Nag 4.2.4) in our enviroment. We have activated debug per device in our
ActiveSync configuration and we receive this error when we try to sync all
mails.

2015-04-16T11:21:57+02:00 NOTICE: [27633] Previous request processing for
synckey {552f7b9a-9d50-4f65-9a60-6bed0a011487}2 failed to be accepted by
the client, removing previous state and trying again.

We have seen a similar error with the same text, but trying to fix it with
the resolution described in this bug (disabling tagging in Turba
configuration) doesn't Work.

Do you know how can we resolve this issue?

All that you need, more info, debug files, please, tell us and we will to
give it to you as soon as possible.

Thanks a lot.

Regards.
