Peter, IMHO the parameter SOGoMaximumSyncResponseSize = 524288 is set too large.
[...] The value is in kilobytes. Setting this to 512 means the response size will be of 524288 bytes or less. Note that if you set the value too low and a mail message (or any other object) surpasses it, it will still be synced but only this item will be. [...] Depending on the email/attachment size it takes some time to fill response buffer. Setting this parameter to a lower value can help to avoid the "disconnects" in OL. I’d suggest to try different value (starting with 10240) and check the outcome.
