Add Alternate Email Address or Recovery Email Address for Office365 Administrator

September 6, 2017

In Office365, depending on the admin role of an account you may want to add an alternate email address for password recovery. This is a basically a self-service password reset for Administrators of Office365. Quick way to do this is with PowerShell:

#Connect to Office365
Import-Module MSOnline
Connect-MsolService
$O365Cred = Get-Credential
$O365Session = New-PSSession â€“ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $O365Cred -Authentication Basic -AllowRedirection
Import-PSSession $O365Session

#Check if the user has an Alternate Email Address (Recovery Address)
Get-MsolUser -UserPrincipalName mwasay@domain.com | select -ExpandProperty AlternateEmailaddresses

#Check if the user has an Alternate Email Address (Recovery Address)
Set-MsolUser -UserPrincipalName mwasay@domain.com -AlternateEmailAddresses mwasay@domain2.com

Set password never to expire for users in a particular domain (Bulk mode)

January 3, 2017January 3, 2017

Let me start by saying that I don’t recommend doing this at all. Password Never Expires is bad security practice, but there are situations that might require it. I had a similar request on how this could be done. Setting it for multiple users:

#Connect of Office365
Import-Module MSOnline
$O365Cred = Get-Credential
$O365Session = New-PSSession â€“ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $O365Cred -Authentication Basic -AllowRedirection
Import-PSSession $O365Session
Connect-MsolService â€“Credential $O365Cred 

#Get a List of user that belong to the second domain
$SDusers = Get-MsolUser -All -DomainName "yourseconddomain.com"

#Setting the password never to expire
ForEach($SDuser in $SDusers)
{
    Set-MsolUser -UserPrincipalName $SDuser -PasswordNeverExpires $true
}

$O365Cred = Get-Credential

$O365Session = New-PSSession â€“ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $O365Cred -Authentication Basic -AllowRedirection

Import-PSSession $O365Session

Connect-MsolService â€“Credential $O365Cred

#Get a List of user that belong to the second domain

$SDusers = Get-MsolUser -All -DomainName "yourseconddomain.com"

#Setting the password never to expire

ForEach($SDuser in $SDusers)

{

Set-MsolUser -UserPrincipalName $SDuser -PasswordNeverExpires $true

}

Setting it for a single user:

Get-MSOLUser -UserPrincipalName user@domain.com | Select PasswordNeverExpires

1	Get-MSOLUser -UserPrincipalName user@domain.com \| Select PasswordNeverExpires

Get PasswordAge for users in a particular domain

January 3, 2017

In Office365 if you have more than one domain in a subscription, there are times where you may want to get the password age for users of that domain. In my case to check which users are covered and meeting policy and get the users addressed.

Get-MsolUser -All -DomainName "yourdomainname.com" | select DisplayName, LastPasswordChangeTimeStamp,@{Name=â€PasswordAgeâ€;Expression={(Get-Date)-$_.LastPasswordChangeTimeStamp}}

1	Get-MsolUser -All -DomainName "yourdomainname.com" \| select DisplayName, LastPasswordChangeTimeStamp,@{Name=â€PasswordAgeâ€;Expression={(Get-Date)-$_.LastPasswordChangeTimeStamp}}

The output will be similar to:

Extending the Booking days for Conference Room Calendar (Resource)

October 13, 2016

By default Office365 limits Resource booking days to just 180 days. The maximum days it can be booked for 1080 days. I like to make resource booking days 1 year from the day of making the reservation/ appointment. Now instead of visiting each calendar and making the change, powershell can help us out.

#Connect to Office365 
$cred = Get-Credential
Import-Module MSOnline
Connect-MsolService -Credential $cred
$s = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic -AllowRedirection
$importresults = Import-PSSession $s

#Get all the Rooms and make the booking days to 365
Get-MailBox | Where {$_.ResourceType -eq "Room"} | Set-CalendarProcessing -BookingWindowInDays 365

Every Exchange user has an OWA mailbox policy that governs what they can and can’t do with their mailbox. Updating this mailbox policy removes the ability for users to create Groups. Because OWA policies are per user, you can limit the ability to create Groups for some users and not others. At this time, the…
