Hi guys,

I am hoping someone can help with this issue that is occurring with email forwarding.

So when a user such as a manager leaves the company we set the forwarding on their mailbox to go to their replacement. The issue is that the replacement is then added to all the important meetings and the old manager is removed, but the calendar invite for the replacement and the calendar cancellation for the old manager get forwarded to the replacement so it causes issues with them accepting the invite and also the old manager being removed.

I was wondering if anyone has suggestions on how to prevent this issue. Is it possible to set email forwarding using powershell or something so that it forwards everything BUT the calendar related emails? If that is not possible is there anything else that could be done?

Any help will be much appreciated.

Don't do that.

Instead give the repacement full access rights on the old mailbox and have them add it to as a second mailbox on their profile.  Then they can choose to respond to those whom they want to notify.
