Updating calendar share in outlook
Fortunately, there is another method that you can use.
On the Web version of Office 365 Calendar, choose Add calendar and select From file.
The best you can do is use Gmail for your messages and Office 365 Calendar on your computer.
If you’re moving from a different calendar platform, such as Google Calendar or i Cloud Calendar, you’ll need to import your dates and events into Office 365 Calendar. Google will extract your data and ask you to save it as a zipped i Cal file.
but you’ll need to have bought it first and at around seventy bucks a year for an individual subscription, it’s not that cheap. You can also find an easy way into Outlook Calendar in Bing.
