POP and IMAP options
Use these options to change the format of meeting invitations and read receipts. The settings you change here impact only what you see in email programs you added to your email account using POP and IMAP settings.
If you don't see this feature, it's not available for the service or account you're using.
Note You only need to change these settings if you added your mailbox to an email program using POP or IMAP. If you set up an Exchange account connection, these settings do not apply

You set the options individually for POP or IMAP. Check the settings in the email program you're using if you're not sure if you added your account using POP or IMAP. Or, if you're not sure, change settings under both POP options and IMAP options.
Send meeting invitations in iCalendar format By default, POP or IMAP users receive meeting requests as plain text messages with Outlook Web App-based links to meeting requests. If you select this option, meeting requests are sent in iCalendar (.ics) format. Recipients can take action on the meeting request directly from their email client.
Note When you use POP or IMAP, meeting invitations are sent in a read-only copy and don't support rich collaboration. The server is not notified about the actions taken (for example, Accept or Decline actions) on the meeting invite. For rich collaboration, use Exchange to connect to your account.
Don't send receipts for message that have been read By default, if the sender of an email requested an acknowledgment receipt, the sender receives an email notification when the recipient opens the email. Select this option if you don't want to send recipients read receipts.
Choose Save.
