I have an issue with ActiveSync on Shaw's side. I use Shaw's Zimbra ActiveSync protocol to keep my Android phone and two computer email clients in sync with contacts and calendars.
Everything was working great until maybe 6 -8 weeks ago. I thought it was something on my side but I have confirmed that it is on the Shaw side.
If I add a calendar entry or edit a contact on Shaw Webmail it doesn't reliably send the entry to all devices.
When I do the same on my devices' email client Shaw Webmail is not reliably updated. I turned on the the ActiveSync logging for my computer email client and the following error is logged:
Web exception: The remote server returned an error: (500) Internal Server Error.<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/><title>Error 500 Mailbox access error</title></head><body><h2>HTTP ERROR 500</h2><p>Problem accessing /service/extension/zimbrasync. Reason:<pre> Mailbox access error</pre></p><hr><i><small>Powered by Jetty://</small></i><hr/>
Before you ask, the password and user name are all good. Set up is all good. Nothing on my side changed.
I tried contacting Shaw Support via web chat but that was useless. The agent wanted me to call ActiveSync. They didn't understand that is is a protocol used by their Zimbra email server. See here: https://community.shaw.ca/docs/DOC-1064#activesync
Is there someone at Shaw that can look into their Zimbra email server settings to see what the problem is?
