I see this topic has come up before, about a year ago, but I haven't seen any true resolution to how this can be avoided so thought I'd check back in to see if anyone has any further insight since this appears to be an ongoing issue with syncing email activity into SalesForce.
Like others have mentioned, it asks that you check back for the email details, weeks go by and the message still insists you 'check back later.'
Any advise as to how the email details can actually be uploaded would be great; as well as any advise as to how this can be prevented in the future as I find it happens a little too frequntly and randomly.
Thanks!
