While sending meeting invite using "icalendar" library I am facing issue with time zone difference in Gmail and outlook mails. When I am sending meeting invitation to outlook it automatically changing time zone IST to GMT. Please help me out to solve this issue.
The below code I used for sending meeting invitation using "icalendar" but it is not working for outlook mail. It is sending meeting invitation for outlook mails but timezone is differing. Please any one help me to achieve it.
Thank you
