I am using smartermail 15 enterprise with all of the most current updates. I am having an error pop up on multiple clients locations, some on domains, some on workgroups, using windows 10 home and pro and using outlook 2013 and outlook 2016. I have a ticket open with smartertools but have not resolved this yet and I am close to giving up. I did dsicover some cert issues maybe and SSL Labs and mxtoolbox give my mail server a pass score etc.Since this is happening across many client locations, it is not a network issue. There must be some weird setting or config with my server that is causing this... not sure. Enterprise customers use Outlook still and I can not ask them to use webmail all day, just won't work for most of them.... This has been happening for weeks and at this point I do not have faith in putting any new customer on my smartermail server and I might switch all my biz clients to hosted exchange.. it just works with outlook.. All client computers and office 2013/16 is updated. I wanted to throw that out there as well. Has anyone seen this error.. can anyone help determine why? I have not been able to narrow down why or when, just when a client hits the send/receive button or types a new email and hits send, this error pops up.. a reboot fixes it for a little while then happens again... some clients it happens every few days. Same error on all clients outlook, except the email address/account of course.
The server configuration prevents you from synchronizing. Contact your system administrator.

Again, I can not ask them to move away from Outlook. I am going to switch a few of them off smartermail to hosted exchange this weekend if I can not get a fix. Them slowly stop using smartermail.. This has been a huge drain on time and resources and not worth trying to figure out any more. This is one last ditch effort to get help before I give up!
Thank you very much for reading.
