"A subscription already exists" error when an Office 365 user tries to add an IMAP or POP account as a connected account

PROBLEM

When an Office 365 user tries to add an IMAP or POP account as a connected account in Outlook on the web, they receive the following error message:
It was not possible create the subscription for account <User>@<DomainName>.com. A subscription already exists for <User>@<DomainName>.com. Try again with an exclusive subscription name.
This issue may occur if a subscription was created in the user's mailbox during an IMAP migration, and this subscription has the same name as the connected account that the user wants to add. 

SOLUTION

To resolve this issue, remove the subscription from the user's mailbox. To do this, follow these steps:
  1. Connect to Exchange Online by using PowerShell. For more information, see Connect to Exchange Online using remote PowerShell.
  2. Run the following command:
    Remove-Subscription <User>@<DomainName>.com -Mailbox user@contoso.com 

MORE INFORMATION

For more information about the Remove-Subscription cmdlet, see Remove-Subscription.
