The My TELUS support website reports that an email problem is due to a 3rd. party email client but I think not. On just one of seven subaccounts (the others were recovered quickly after server problems in August), the IMAP server still refuses to sync emails lost and reportedly later recovered after the server problems last August up to whenever the subaccount has been reinstalled on an iPad. Specifically, the subaccount a1e15509 sees no messages between Aug. 18 and when the account is again setup on the iPad. In short, IMAP folder syncing is not working in that isolated case.
It seems that TELUS' IMAP service is still not syncing right. Microsoft Office Outlook on her PC works fine. TELUS support has yet to find a solution, so I am still looking for suggestions.
