In Outlook 2007 & Exchange 2007 we have an end user that needs to schedule a recurring meeting with no end date. When she tries this, she gets a permission denied error. When I try it (as Domain Admin), it works.

This is the exact error:

  • Your meeting request was declined.
  • It did not specify an end date. The end date must be before 12/13/2012.

The only 2 permission sets we have on the calendar are Default:Author and Anonymous:None.

I am guessing that the solution to this lies somewhere within a Exchange Power Shell cmdlet, but I am not sure.

Does anyone know how to fix this so that she can use the "no end date" feature?

Can you schedule any recurring meetings at all? This is usually disabled for a reason. They tend to break things. – Zoredache Dec 13 '11 at 16:02
She can schedule meetings until the end of 2012. – jftuga Dec 13 '11 at 16:26
And she need to sceudule past the end of the world? ;) – Zoredache Dec 13 '11 at 16:31

She might be restricted by the so called BookingWindowInDays attribute, which specifies the maximum number of days into the future, that meetings can be booked:

To override this attribute, update her mailbox calendar (and the calendars of all resource mailboxes she needs to book) with the EnforceSchedulingHorizon property set to false, like this:

Set-MailboxCalendarSettings -Identity "user" -EnforceSchedulingHorizon $false
