Calendar sharing is not available with the following entries because of permission settings on your network

A user came up to me this morning and informed me that they couldn’t share their calendar with a colleague, as they keep getting the error message “Calendar sharing is not available with the following entries because of permission settings on your network.”

Basic troubleshooting steps showed that this issue is simular to error is 0x80070057-00000000-00000000 and all that was really required to resolve it was to select the person from the GAL (Global Address List) rather then typing it in manually.

Another factor involved was that this colleague hadn’t been updated in the users Offline Address Book and this was the reason for typing in the email address in the first place. This was resolved by simply downloading the updates to the GAL.

Mobile Phone Dynamic Distribution Group

The other day, the boss came to me and asked me to setup a distribution list for everyone who has a company issued phone.

GREAT, I don’t want to manage this distribution list.

Luckily for me, only users who have been issued company phones have their mobile numbers in Active Directory, so off to PowerShell I go.

All I need to do is create a dynamic distribution group, which with the GUI in Exchange 2010 is pretty limited, so as previously mentioned, I’ll have to use PowerShell. But what is a dynamic distribution group? I’ll let Microsoft Explain it:

Dynamic distribution groups are mail-enabled Active Directory group objects that are created to expedite the mass sending of email messages and other information within a Microsoft Exchange organization.

Unlike regular distribution groups that contain a defined set of members, the membership list for dynamic distribution groups is calculated each time a message is sent to the group, based on the filters and conditions that you define. When an email message is sent to a dynamic distribution group, it’s delivered to all recipients in the organization that match the criteria defined for that group.

So there you have it, this is exactly what I am looking for, and PowerShell is the way I am going to do it.

Firstly, I’ll give a name of the dynamic distribution group, in this case “iUsers Mobile”

Get-DynamicDistributionGroup "iUsers Mobile"

Now, I’ll need to set the filter that I want for this dynamic distribution group, in this case, obviously it will be the mobile number. Since all mobile numbers start with a 0, using –like “0*” will match all numbers in the MobilePhone AD field with a wildcard for any combination of numbers after the leading 0.

Set-DynamicDistributionGroup -RecipientFilter {MobilePhone -like "0*"}

Pipe them both together and now I have a 1 liner that will assist with my desire to NOT have to manage this distribution group.

Get-DynamicDistributionGroup "iUsers Mobile" | Set-DynamicDistributionGroup -RecipientFilter {MobilePhone -like "0*"}

So there you have it, any comments and questions are welcome.

Exchange 2010 – Change Mailbox Quotas with Exchange Management Shell

Today while playing with that Exchange Management Shell (EMS) I noticed that 1 of our users had a ProhibitSendQuota set to 2GB, while all our other users have it set to unlimited.

So off I went to try and figure out how to change this setting in PowerShell/EMS, which turned out to be pretty easy.

To change the quota for a single user type the following at the EMS prompt:

Set-Mailbox –Identity <alias or email address>  -ProhibitSendQuota Unlimited

You can also specify the amount you want for the quota:

Set-Mailbox –Identity <alias or email address> -ProhibitSendQuota 209715200
OR
Set-Mailbox –Identity <alias or email address> –ProhibitSendQuota ‘2GB’

Other quotas you can change IssueWarningQuota and ProhibitSendReceiveQuota

To reset all your quotas to defaults:

Set-Mailbox –Identity <alias or email address> -UseDatabaseQuotaDefaults $true

Error is [0x80070057-00000000-00000000].

This message could not be sent. Try sending the message again later, or contact your network administrator.  Error is [0x80070057-00000000-00000000].

 

RESOLUTION: When adding in recpients, make sure you add them using either the GAL or by typing in there full address. The issue seems to be with auto complete email addresses.
