Rated 5 out of 5 stars
Unfortunately I was not able to get the either the pro (with trial license) or the standard version to talk to the server properly. While things are fine up to and including searching for objects on the CRM, the actual archiving of emails does not work. Tested with SuiteCRM Version 7.2.2 (Sugar Version 6.5.20 (Build 1001)). Pity, would be a very helpful plugin.
[EDIT] After working to debug the issue with the developer, what finally resolved the issue was to upgrade from ubuntu LTS12 to LTS14 - the critical part was probably the php version. Now everything works as advertised (and fast) and I'm happy to give the plugin the full rating.
I'm sorry to hear you were unable to archive emails into your SuiteCRM system. However, connecting to any remote resource is a partnership between client and server, and it seems just a tiny bit unfair to leave a one star review of the client without indicating that all was done to eliminate possible problems with the server.
We would encourage any potential or active users of the extension who suffer similar issues to report them on the support forums.
[UPDATE] Many thanks to foobar for following up on the review
