Hello Osticket,
Thank you for your great product but its use in my environment is being threatened as the only way to get mails from the Exchange Online is through IMAP which Microsoft has deprecated, this is nothing new, I am sure you have been hearing of this over the past 2 years. Nonetheless, there has been some amount of reticence on your part concerning this and what you solution is for this or the timeline to expect a solution. If I become a paid subscribing user will I have a solution for this?
