Received the following message in my Office 365 account today - 2016.10.08:
In order to continue accessing your Outlook.com emails via Outlook on the web in Office 365, re-connect your Outlook.com account by following the steps below:
• Wait until you have been migrated to the new Outlook.com. To check if you have been migrated, review the support article here.
• Log in to Outlook on the web to access your Office 365 work or school account.
• Go to the connected accounts options page by clicking Settings -> Mail-> Connected accounts.
• Delete your existing Outlook.com account and re-add it as an IMAP connection.
• For more detailed instructions, please refer to the help article here. If you face any other issues, please feel free to contact Outlook support.
(Needles to say that the support they mention here is of no use)
I have no idea what all the settings for IMAP are supposed to be and am hence unable to re-connect my outlook.com account to my office 365 as instructed by Microsoft.
