msExchHiddernFromAddressList is not synced to Office365

Situation:
You need to hide Exchange Online mailbox from address list and have AD synchronization in place, but no local Exchange.
You then extend Active Directory schema by using local Exchange installation with setup.exe /prepareschema switch.
Next, you are fire up refresh directory schema in AD Connect, and do full AD sync, and...
No, msExchHiddenFromAddressList attribute is not syncing, even if it is set in AD account attributes and seen on AD Connect connector.

Solution:
If you have made all the previous steps, then probably your AD account has mailnickname attribute not set


After fill it with proper data (alias), and do another AD Connect AD sync , you can  see your msExchHiddenFromAddressList synced at last.

Migration between two Office 365 tenants

In the era of cloud solutions, soon or later we will face the challenge of connecting two of them together. Merges and acquisitions of companies which possess separate cloud IT infrastructure needs to be joined, unified and also simplified if possible.
Using experience after few successful migrations, I will try to explain here the most important things to consider in similar projects, when Office356 is involved.
This is not step by step instruction – only lessons learned from the migration field.
At the beginning - things which appears every time you plan a change in the organization.

Determine customer expectations and goals

The most important thing, which – when chasing for time and money some people forget - the success of the project depends on the fulfilment of customer expectations. Dot.

Office365: Removing all Exchange aliases from user accounts - moving from/to O365

In order to remove the domain form the Office365 subscription,  you need to delete all aliases.
There are many articles on the subject, how to remove one alias, but no data about how to remove ALL aliases from ALL accounts.
This little script will help you when you need to move to another O365 tenant or from cloud to on premises Exchange.

$alias = Get-Mailbox -resultsize unlimited

foreach($x in $alias)
{
$x.emailaddresses = $x.userprincipalname
Set-mailbox $x.alias -emailaddresses $x.emailaddresses
}

Office365: Change public folder default quota limit

Hi,
In the Exchange Organisation, there are quotas per Public Folder mailbox for the items ...

..and as a whole organisation:

If you receiving warnings about quota when using public folder, then you need to change organisation wide settings. For this example we have had DefaultPublicFolderIssueWarningQuota set to 1.7GB and DefaultPublicFolderProhibitPostQuota set to 2GB.
Now, we change it to 35 and 40GB respectively:


And all is set now!
