No email or folders visible when using IMAP account with Outlook 2013 or Office 365

/0 Comments/in /by

The problem seems to be caused by two updates from Microsoft; KB2837618 and KB2837643.

There is a simple solution though:

  • Right click on the affected account in the left pane and select IMAP Folders
  • Below the list of folders, uncheck the box for “When displaying hierarchy in Outlook, show only the subscribed folders.“
  • Exit Outlook 2013 / Office 365 and restart it
  • At the next synchronization the folders and mail will (hopefully) be visible

Microsoft Office 365 SSL certificate error in Outlook [solved]

/0 Comments/in , /by

Clients moving over to Office 365 who had purchased a valid SSL certificate for their mail server still got SSL certificate errors in Outlook and mobile clients. This was despite the mail service was equipped with a valid SSL certificate (not self signed, but issued by a real CA).

It turns out here that Outlook seems to investigate https root domain (i.e. the customer’s web site) for auto configuration before trying autodiscover.customerdomain.com. And if there is no valid SSL certificate installed on the customers web site, an error is displayed. This was verified by examining the customer’s web site logs where we could se repetitive accesses to /autodiscover/autodiscover.xml.

If only Outlook just would have ignored the SSL error and continued to the next method….

A simple solution was just to add a valid SSL certificate to the customer’s web site, and the problem was solved. That way Outlook didn’t get SSL certificate error when trying to retrieve the non-existing autoconfiguration information from the customer’s web site.
