Hi,
I've the same problem as the one related several years ago on this thread:
I'm using both Zoho Mail (Web & Mobile iOS) and when I receive invitates from Outlook users (that are not using Exchange as mail server, not sure if it's related, in my case the user at the other end is using Outlook 2016 on Windows) I just see an empty email.
Here is the beginning of the mail content (can't post the whole since it contains personal data):
BEGIN:VCALENDAR
PRODID:-//Microsoft Corporation//Outlook 16.0 MIMEDIR//EN
VERSION:2.0
METHOD:REQUEST
X-MS-OLK-FORCEINSPECTOROPEN:TRUE
Is this normal ? I would expect Zoho Mail to handle such format.
Thanks for your feedback.
Regards,
Jean-Marc
