z-push sync email iOS more than one month

[remmedia]

Z-push yncing for large mailboxes and sync more than 1 month doesnot work.

it only loads a few old mails and than stops with error.

As a workaround you could change to sync only 1 month in past, but that is not a real solution.

It worked like without errors until some update of group office this summer.
