A demonstration of one way to get shared mailbox permissions exported to a CSV file. We needed both users, groups and users in groups (so, a recursive search). Only Shared mailboxes had to be included, we could identity these by a simple rule:
the first portion of the primary email address does not contain a dot
See line 126 and 127 for this rule if you need a different method.
Edit: make sure you replace CED\ with your own domain! Sorry bout that…
This export excludes Deny permissions and looks for users in groups up to 2 levels deep. Credits to Piotrek for his Get-ADNestedGroupMember function.
Because I couldn’t quickly find a good script/tool to make a report of my Public Folders that includes a complete drilldown including if they’re mail enabled, what email addresses it has, who has rights on the folder and what size the folders are, I’m sharing this script with you 🙂
Edit: added support for Exchange 2010, uncomment the correct section and comment the 2007 code if you run this on 2010.
A warning though, calendar permissions in Exchange Online can easily become corrupted. I’ve been in touch with support several times, but their only fix is to tell the user to remove and reapply the permissions, which is a sure way to annoy your users during migration.
This powershell snippet will tell you which mailbox is actively forwarding email, in what method (dual delivery or pure forwarding), to which email address and if the corresponding contact still exists and is active.
