Exchange: How to restrict conference room only to specific users?

By default resource mailbox process meeting requests from all users. What if you need to restrict to specific users who can book a resource?

All my investigation pointed to do this:

Set-CalendarProcessing  -Identity resourcename@domain.com  -AllBookInPolicy:$false

Set-Calenderprocessing -Identity resourcename@domain.com -BookInPolicy “username1″,”username2″,”username3”

Now I checked what AllBookInPolicy means and TechNet says “The AllBookInPolicy parameter specifies whether to automatically approve in-policy requests from all users.”.  OK sounds like a correct setting.

Then I checked what BookInPolicy means, “The BookInPolicy parameter specifies a comma-separated list of users who are allowed to submit in-policy meeting requests to the resource mailbox. Any in-policy meeting requests from these users are automatically approved.”

BookInPolicy means the it will automatically approves all meeting requests regardless of availability. That’s NOT good. And these solution didn’t work for me.

So I thought creative and decided to do this:

Set-Mailbox -Identity “resourcename@domain.com” -AcceptMessagesOnlyFrom “username1″,”username2″,”username3”

Ta.Da! That satisfies the only specific users can book the resource by sending meeting requests. And resource mailbox automatically process the meeting requests by accepting or rejecting depending upon availability. <.. Evil Genius laugh ..>😮

Mac: Outlook throws Error when compose emails “Some of the files in this Web page aren’t in the expected location”

You are getting this error whenever you compose a new email or replying to an email.






It means your HTML signature has a bad formatted hyper-link or “Text to display” property.

  • Open Outlook –> Preferences –> Signatures
  • Right click (on each) hyperlink and choose Hyperlink –> Edit Hyperlink

That’s it. Send your emails in peace.🙂

Exchange: “You don’t have sufficient permissions” when modifying or removing a DL

You are getting the following error when you try modifying or deleting an DL in Exchange Admin Center or in PowerShell.

You don’t have sufficient permissions. This operation can only be performed by a manager of the group.

Funny thing is sometimes you can’t even add yourself as a manager of the group (ManagedBy attribute).

But it says clearly DLs needs an owner/manager so you can modify or delete the DL.

Solution 1: Add yourself as owner of the DL.

  • Connect to Exchange Management Shell or connect to Exchange Online in PowerShell
  • Type this command to add yourself as a owner:
    • Set-DistributionGroup <DL Name> -ManagedBy @{Add=”UserPrincipalName of yours”} -BypassSecurityGroupManagerCheck
  • Now make the changes you want to do in this DL

Solution 2: If you want to remove the DL, then

  • Connect to Exchange in PowerShell
  • Type this command to delete the DL
    • Remove-DistributionGroup <Group Name> -BypassSecurityGroupManagerCheck

By now you figured out BypassSecurityGroupManagerCheck option did the trick.🙂

Outlook: Name Could Not be Matched to a Name in the Address List

If you try to create a new Outlook profile for a Exchange mailbox and you get “Name Could Not be Matched to a Name in the Address List”, there could be an easy answer.

The error message explains to you that target mailbox is not listed in Global Address List. That means you may have checked the box for Hide from Address Lists in Mailbox properties.


To create the Outlook mail profiles, you need to clear the check box for Hide from address lists in Mailbox properties in Exchange web console. You can hide the mailbox from address list after you created the Outlook profile.
