I would just create a Distribution group that has everyone in it, and then send out a reocurring invite ot the entire organization.

The problem is that not everyone will accept it.

Force everyone to atleast tentatively accept calendar invites using the following command:

Set-CalendarProcessing mailbox -TentativePendingApproval $true

For every mailbox:

Get-Mailbox -Result Size Unlimited | Set-CalendarProcessing -TentativePendingApproval $true

Or you would have to play with the the EWS API's to add it for everyone.

Hi Carltonw,

Thank you for your question.

I am sorry that we could not add a  biweekly remainder.  We just add reminder every week as the following snapshot:

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim

That would work except users can delete it before it's added to their calendar.
