Office365: Limiting access to Office 365 using ADFS

If you need to restrict access to Office365 for users outside your company at all or just for group of them then you need to use ADFS servers.

When you have set them properly and you can be authenticated by ADFS, then you can configure ADFS claims to restrict the Office 365 access.

First, I've tried use the solution provided in this link:

But, this not work in my environment.

I've been looking for article below, but can't find it as "limiting access".
Then when asked Microsoft they give me the right link.

Here is the right link:

Office365: Add new licence / subscription key to the tenant


Today easy and short tip, but you could wander around for hours searching this:
When you have bought new licences you can easily add key to the subscription.

Go to the Volume Licencing Center at:
(If you have not logged in earlier here you need to register with e-mail account provided with licence order)

Get (copy) your subscription key from the license.

Next go to this link:
and paste the key.

That's all!

If you have used trial licences you'll have to change your user's licences from trials to the new one.

Office365: Cannot move, migrate mailbox. The operation couldn't be performed because object couldn't be found on...

The operation couldn't be performed because object couldn't be found on...

This error appears when you try to move (migrate) mailbox from on premises Exchange to the Office365. It means that object with same date exists in both sides and it differs in some way.
It could happen if you have created mailbox in Office365 without migration from on premises Exchange.
To resolve this issue, you need to remove user from Office365 side and synchronize it again and then migrate mailbox to the cloud.

So, connect to Office365 from Powershell.
Then run:
Remove-MsolUser -UserPrincipalName

Next, run:
Remove-MsolUser -UserPrincipalName -RemoveFromRecycleBin

Now, wait for dirsync replication or force it and you should have the ability to move the mailbox to Office365 from onprem Exchange.

Office365: MRSProxy.svc issue - update

Some time ago I wrote a post about MRSProxy.svc problems:

I have not got into account migration endpoint settings.
When this issue appeared again and I cannot move mailboxes to the Office365 at all, then I have checked endpoint settings.
It seemed that the password used for migration endpoint has been changed by other administrator and was not refreshed in Office 365 panel.
After entering password again, I can again move mailboxes!

To change migration endpoint password, go to:
Exchange administrative panel, users, migration.
On the right, low corner, check migration endpoint , click Details
Change password for administrator or enter new admin credentials.

Office365: Cannot remove custom domain

When you need to remove one of your custom domains from Office 365 you can find that you cannot do this.
One of possible issues with this is when you are working in hybrid environment and if you have DirSync working which synchronizes your AD to the Microsoft cloud.
This is one of undocumented behaviors of Office 365, that you cannot remove domains, i.e. not all of them, cause I have just done this without problems with some, but still cannot do this with others.

When I have searched for resolution on Office365 Community and other Google sites and blogs, I found nothing than "Before you remove a domain name from Office 365, you have to remove anything that is using the domain name":

Fortunately, if you are working in hybrid environment, the shorter path exists.

First login to your Office 365 tenancy from powershell:

Get-MsolUser -DomainName

If you get some entries here, then you have to disable this users licences in Office365 panel

If now Get-MsolUser -DomainName gives you empty return, then you can go further. If not, you have to disable licences assigned to users with your domain e-mail addresses.

After getting empty result for Get-MsolUser -DomainName , you can

Get-MsolGroup -All | where {$_.proxyaddresses -match ""}

You probably see some entries here.
You will need to remove addresses with your domain aliases from those groups.
If your company have dirsync configured, then you will need to remove those aliases from AD.
If you are running hybrid confirutation, with Exchange on-premises, you can remove those aliases from Exchange side.

After removal wait about 15 minutes, force DirSync synchronization and check on the Office 365 side, again running the:
Get-MsolGroup -All | where {$_.proxyaddresses -match ""}

If, finally you will get empty result, you can remove the domain from Office 365 side.

Wish you luck!

Exchange 2010: EMC initialization failed

When you remove one of your Exchange servers, then you have chance to encounter EMC initialization error.
This is because removed server was chosen as the best to be managed by EMC.

1. Go to the c:\Users\username\AppData\Roaming\Microsoft\MMC
2. Delete “Exchange Management Console” file:

3. Run regedit

Office365: Force DirSync to synchronize AD with the cloud

If you don't want to wait for dirsync to operate within its interval, you could force it to make instant synchronization.
To do this, follow the procedure:

1.Run Powershell
2.Go to the directory where you have installed dirsync tool.
In my case it was:
Program Files\Windows Azure Active Directory Sync
3.Run the script:
4.In new window which will appear, run 

The directory has been synchronized.

Exchange 2010/2013: Reconnect mailboxes for deleted users

When you delete user account from AD and not delete mailbox itself, it is possible to reconnect this mailbox to the other user.
First find in which database this mailbox exists. If you remember only name of the user, you can use -match operator:

Get-MailboxDatabase|Get-MailboxStatistics|where {$_.displayname -match "Kowalski"}|fl displayname,mailboxguid

Then you should get MailboxGuid you need.
Next, select or create mail disabled user and point it with connect-mailbox command

Connect-Mailbox MailboxGuidhere -database databasename -user newuser

Office365: Cannot use connect-msolservice cmd-let

When I've tried to use Connect-MSolService to manage users in Office365 from powershell it turned out that I can't use this cmd-let.

I thought that I didn't install some of components probably, but this was not the case.
I'm in the middle of migration from on-premises to the cloud.

I have not finished configuring main domain and I've tried to connect to Office365 with the main domain which MX record still points to on-premises server.

If you need to manage user accounts in Office365 and you didn't moved your domain the cloud, use the WWW panel(EAC).

After migration I still cannot use MSolService module.
I've found the right reason: the module was in System32 path folder, which is used by 32bit systems.
After moving it to the same place in SysWow64 path, module has been loaded correctly.
So, the really fix is:
Copy folders MSOnline and MSOnlineExtended from C:\Windows\System32\WindowsPowershell\v1.0\Modules

Office365: Outlook 2007 cannot connect / configure profile

During the migration to Office365 we've prepared many computers with Office2007 installed.
Some of them could connect to Office365 immediately and others not.
Because we've had set gpo's for Outlook settings and autodiscover worked properly it was hard to find what caused the problem.

Problem - authentication
The problem was with authentication. Problematic Outlook's didn't have anonymous option in the security settings on connections tab.

Solution - Microsoft Updates
Outlooks which caused problems were set to NOT get Microsoft Updates.
After check the option to automatically get updates in Outlook settings and install them - anonymous option was in place and profiles has been configured properly.

Office365: Manually configure Outlook profile

If you have problems configuring Outlook profile with autodiscover, then reading this should help you. If you need to resolve this, check this post:

Steps for configure Outlook Office 365 profile manually:

1. Logon to Office365 from powershell as described here:

2. Get your mailbox cloud ExchangeGuid:

Get-Mailbox mailboxname |fl ExchangeGuid, OriginatingServer, PrimarySmtpAddress,UserPrincipalName

3. Copy this data to your computer with Outlook.

4. Go to your computer with Outlook.
5. Open Mail in Control Panel options. Click Add New Account.
6. Choose Manually configure server settings or additional server types

7. Choose Microsoft Exchange or compatible service:

8. Click More Settings:

9. In the connection tab, select Connect to Microsoft Exchange using HTTP:


10. Click Exchange Proxy Settings...

11. Fill in the tabs:


Click OK.

12. Go to the Security tab and select "Anonymous Authentication" in Logon network security:

Click OK.
13. In the Add New Account window fill fields with data that you've gathered from Office365

14. In the Server: you can use ExchangeGuid which is mailbox guid with the format:
ExchangeGuid@domain, for example

you can use Originating Server Name which will look for user name you provided, for example:

15. In the User Name, enter user PrimarySMTPAddress

Click Check Name

You should then get credential pop-up which is good sign:

16. In the user name field use the UserPrincipalName - probably the short alias.
17. Enter the password and...

Voila! You are in.

Well, you should, but... If you still have problems configuring this, then consider following, mostly if you had this profile earlier, for example after migration from on-premises to the cloud:

1.       Delete all Outlook credentials from Windows Credential Manager

2.       Go to the Control Panel/Mail

3.       Delete current profile

4.       Create new profile
