The iOS device will not sync email or displays an error saying that it cannot connect to server.

This could be an issue with a corrupt item in your mailbox. On an ActiveSync device, you would receive the error code: 0x86000108

You can resolve this by setting the iOS device to sync all items in the Inbox and/or Calendar, depending where the corrupt item is.

To set the Inbox to sync all items:

  1. On the iOS device, go to Settings > Mail > Accounts.
  2. Select your account.
  3. Select Mail Days to sync > No Limit.

 

Notes:

  • In order to prevent synchronization issues Intermedia does not recommend to use Mail Days to sync > No Limit if there are more than 3000 items in the inbox. For more information please refer to the article: Recommended Number Of Items In A Folder On Exchange.
  • for iOS9 and lower on the iOS device, go to Settings > Mail, Contacts, Calendars > select your account.

To set the Calendar to sync all items:

  1. On the iOS device, go to Settings > Calendars.
  2. Select Sync > All Events.

 

Note: for iOS9 and lower on the iOS device, go to Settings > Mail, Contacts, Calendars > scroll to the bottom and select Calendar
