Setting Calendar permissions right after mailbox creation

Customer is running Exchange 2013 with approx. 2500 mailboxes. When looking at calendars and sharing information through the availability service only the availability (free, busy or tentative) is shown. No details are shown by default.

Customer now request to publish more information so that users that want to schedule a meeting can see the details of other user’s appointments. This should not only be configured for existing users, but new users should receive this setting directly when provisioned.

For example, when configuring this for a user called Kim Akers (kima@exchangelabs.nl) for all users you can use the following Exchange PowerShell command:

Set-MailboxFolderPermission kima:\Calendar -User Default -AccessRights Reviewer

When scheduling a meeting with Kim Akers I can now see her appointment details in Outlook, and I can open the appointment to see all details (read-only) of this appointment as shown in the following two screenshots:

Note. Check the Set-MailboxFolderPermission article on Microsoft TechNet for all details regarding the permissions that can be assigned.

DKIM in Office 365

Microsoft has implemented DKIM, DMARC and SPF in Exchange Online, the only thing you have to do is enable it. The only thing for DKIM you have to do is create two CNAME records in DNS and enable DKIM in the Exchange Admin Center.

DKIM CNAME records

The CNAME records you have to create for DKIM look like this:

selector1._domainkey.contoso.com
selector2._domainkey.contoso.com

Selector1 and selector 2 are the 2 selector tags (in Office 365 these will always be selector1 and selector2), the _domainkey is a default tag that will be added. Of course you have to replace the contoso.com with your own domain.

The CNAME records have to point to the following locations:

selector1-contoso-com._domainkey.contoso.onmicrosoft.com
selector2-contoso-com._domainkey.contoso.onmicrosoft.com
