Thor,

Shaw uses Zimbra. The auto set up feature did not work when I set my accounts up on eM Client. I had to manually set then. Funny thing though when I set up my wife Android phone and my Blackberry, they were both able to auto set up the account and work perfectly.
I’ll have to double check this when I get home but in manual mode I don’t think eM Client allows you to just set up AirSync (now called ActiveSync). So you have to add add your IMAP and SMTP server information plus the AirSync server information.
Here are my instructions for how to set it up. See the post on July 28, 2016

When I initially set this up everything worked perfectly. However, some months later the copy to sent folder stopped working. If you use my set up plus the copy to sent folder work around you should have a 100% working system.
It seems to me that there is a bug with email eM Client because both Android and Blackerry 10OS and Outlook (2003) have no problem whatsoever in communicating with Shaw’s Zimbra email server. My devices have worked for years on Shaw/Zimbra. Only eM Client doesn’t work 100% (which odd because it did work and then suddenly stopped without me changing a thing).
Good luck. Let me know if this works for you.
