  • /utf-8 - uses imap_utf8($string) to decode a string
  • /iconv - uses iconv_mime_decode($string) to decode a string
  • /mimeheader - uses mb_decode_mimeheader($string) to decode a string
  • /purge - delete message after import from mailbox

To add shared mailboxes follow the documentation: Shared mailboxes in Exchange Online.

Error: Application is not configured as a multi-tenant application

Usage of the /common endpoint is not supported for such applications created after '10/15/2018'. Use a tenant-specific endpoint or configure the application to be multi-tenant.

Exchange Online Kiosk, Microsoft 365 F3 & Office 365 F3 plans do not support IMAP.

Error: URL may not contain a query string

If the URL may not contain a query string error occurs when creating an application or adding a Redirect URI, please follow these steps:

  1. When creating the application, for Supported account types select Accounts in this organizational directory only.
  2. After creating the application, go to Authentication tab and in Supported account types set Accounts in any organizational directory (Any Azure AD directory - Multitenant)

The cron job returns the information "The folder is empty"

Typically, this error occurs when IMAP is disabled or your plan does not support IMAP because the account does not have access to folders. If IMAP is enabled and the plan supports IMAP, then most likely the connection was made from a different account than the one specified in the Email AddressAfter pressing Connect you should be redirected to the login page and you should log in with your Email Address account. If you are currently logged in to another account, the login page is skipped after pressing Connect. The authorization will succeed and the connection will be made correctly, but the import will not work because the current account does not have access to the messages.

Follow these steps:

  1. Sign out of Azure/Microsoft.
  2. Go to the import method configuration in ticket departments.
  3. Press Disconnect.
  4. Then press Connect.
  5. You will be redirected to the login page, here you must log in to the account which is specified in Email Address
