I’m currently working through a Lync cut-over for a customer to Office 365. As they are moving from a single on-premise Lync 2010 server and didn’t wish to go the hybrid route, we are running through a cut-over process for users. Ideally we would like to do this with no interruption to existing users (ie, updating DNS settings for all). As such, would like to manually configure the test users to point directly to Office 365 Lync Online/Skype for Business – preferably with as little hands on as possible. Thankfully, these settings can be configured in the registry. These registry keys to set can be found:
I am packaging these settings into the installer for SCCM deployment but this could easily be adjust using a GPO, script, etc.
Recently, while working through an Office 365 Hybrid migration for a customer, we needed to bring the Exchange Online Protection IP address ranges into their firewall for policy changes. Microsoft publishes this list here: https://technet.microsoft.com/en-us/library/dn163583%28v=exchg.150%29.aspx. Unfortunately, I needed them in the following format:
config firewall address
set subnet 188.8.131.52/22
Thankfully, this was made much easier with using Word find/replace with the following syntax:
Replace: edit ExchangeOnline-\1.\2.\3.\4^lset subnet \1.\2.\3.\4/\5 ^lnext^l
Simply copy and paste into SSH, upload script, etc. and you’re sorted!
Recently after configuring Active Directory Federated Services for a customer for Azure AD Premium/Office 365, we received the following error while testing user login to https://portal.office.com:
Sorry, but we’re having trouble signing you in.
Please try again in a few minutes. If this doesn’t work, you might want to contact your admin and report the following error: 80041034
The obligatory Google search showed potential fixes relating to cached ADFS entries for users post-UPN changes (which we had done as a prereq. for MS Online Services). We ran the LsaLookupCacheMaxSize fix here: https://support.microsoft.com/en-us/kb/2535191. This did not resolve the issue. The other suggestions found online were to convert the MSOL Domain from Federated to Standard and back again. While I’m sure this would have helped, the easier option was to remove the Relying Party trust from ADFS:
Followed by running the Update-MsolFederatioDomain -DomainName ourexternaldomain.co.nz
This then placed an updated/correct copy of the Relying Party trust into our ADFS server which resolved the issues!
So the basic idea behind this is to permanently hold onto a users mailbox if they have left the company and we may need to review their mail at another time.
There is a requirement for the user to have an Archiving License with In-Place Hold assigned to his mailbox. At the stage of writing this, E3 is the only license available with the In-Place hold.
My client only has E1 licenses applied to their mailboxes
To work around this I have had my client agree to purchase a Single E3 License which we can move around to the mailbox we need to Archive
First of all go into Exchange Admin Center & select Compliance Management
Select the Plus button to Add a new in-place e-discovery & hold policy
Add a name as required. I have labelled mine Terminated Employee’s
Select Add and find the Mailbox you would like to Archive. Ensure the E3 License is applied
The Search query we ignore
Select the box to Place content matching the search query
and ensure Hold indefinitely
Now feel free to remove the mailbox
I have recently been utilizing MigrationWiz https://www.migrationwiz.com/ for some of my Office 365 migrations. The easiest way to do this is my utilizing an admin account – both on your Exchange on-premise or 3rd party hosted solution & on Office 365. In order to this, simply connect via Powershell and ran the following commands:
$LiveCred = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirection
