I have recently upgraded to GW7 (SP1) and installed GMS, we have Nokia
E70's and my findings are the following.

Phone has to be latest firmware version.
Intellisync client has to be the latest version.

In doing this I can :

retrieve email from groupwise.
Sync my calendar both ways (from phone to GW and vice versa)
Sync my contacts from GW to phone

but I cannot :

Send an email from the phone
See the contents of GW folders on the phone
update my mailbox from the phone (ie read emails become read in GW
client, or deleted emails get deleted in the client)
Sync my phone created contacts to GW

Am I missing anything?

is there any timeline for resolution of any of these issues that any
knows about?

many thanks
