importer.php:262 hex2bin() - warning-message

Hello Forum,

i’ve got a ton of warn messages in my z-push.log:

08/08/2017 09:57:47 [16223] [WARN] [user] /usr/share/z-push/backend/kopano/importer.php:262 hex2bin(): Hexadecimal input string must have an even length (2)
08/08/2017 09:57:47 [16223] [WARN] [user] MAPIUtils->IsInEmailSyncInterval: Message is OUTSIDE the synchronization interval
08/08/2017 09:57:47 [16223] [WARN] [user] ImportChangesICS->isModificationAllowed('U3d69c:f0bc882a8e0f410aa9765bd325976fe763b5a9000000'): Message in Email is outside the sync interval. Data not saved.

The Error with “Message in Email is outside the sync interval. Data not saved” is reported already, but with calendar items, not with mail-items. (


Hi Coffee_is_life,

it would be helpful, if you could provide more information. Does it happen when the user deletes a message on his mobile? Or on a regular sync?

Is this the complete log for that request? Could you provide WBXML log?

What mobile device is it?


Normal (initial and following) syncs to outlook 2016
