As reported elsewhere in the forums in the fall of 2006, having the Always on sync schedule in your mail for exchange profile on a nokia e61/2/70 would give an error.

However, now there's no error, just nothing happens.

When I switch sync sched to 15 minutes instead, everything works.

It was reported that this would be fixed in 4.5.

I am using ZCS net 4.5:

236338110 2007-04-23 20:44 zcs-NETWORK-4.5.4-20070418.UBUNTU6.tgz

with the Nokia Mail for Exchange client on my e70:

1233952 May 24 15:07 MailForExchange(1.5.0).SISX

With 'Always On' I see alot of this in the sync.log:

Code:

Occasionally, I dont know when, I also see the <Ping> section display:

Code:

</Ping>
after authenticating with a login, but no sync.

Is this a Nokia M4E or a ZCS 4.5 net issue? Is there a work around?

It's really too bad there's no 5 minute or 3 minute sync schedule, that would be the same as 'always on'.

Thanks.
