Dear Suzanne Kean1
Thanks for your response! Very sorry for late reply!
Based on your further description, may I know whether you are using classic Outlook? If yes, and if you would like to export shared calendar to Excel/csv, you can do following steps:
Go to your calendars in Outlook and change the view to list view>right clicked on your shared calendar and clicked "Copy Calendar">From there, created a folder to copy the shared calendar to, that was under your personal account. (You should be able to paste it anywhere under your exchange account)>Once the shared calendar was under your personal account> go into File > Open & Export > etc. select the shared calendar that was copied into your personal account to export as a csv.
You can also use a list view and copy and paste the events into Excel or a text editor. If you need to export just a few items or use a filter, this works well and is just as fast as exporting to excel.
About changing view: just click calendar button>choose calendar which you want to export>click the view button on the top>click change view option>choose list

If you are using new Outlook, please switch back to classic Outlook, you can refer to toggling out of the new Outlook for Windows preview.
Thanks for your precious time and your understanding would be highly appreciated. Have a nice day!
