Export Office 365 User’s Mailbox Last Logon details to CSV

 Hello Everyone,

I was trying to export O365 mailbox last login details to CSV by using few of the scripts but all the scripts had given me the wrong details.

After I was going through this blog I came to know that Last login details pulled by Get-MailboxStatistics gives the incorrect details. Even the below blog says.

I followed this blog: https://o365reports.com/2019/06/18/office-365-users-last-logon-time-incorrect/

Hence I used below url script to pull the details.

Creating Forest Trust between different forest

Hello Readers,

Currently working on Active Directory Consolidation project with below details:

There are total of 16 different forest with different locations.

All 16 forests running on Windows 2003 Server Standard with SP2 &
Windows 2003 Server Enterprise with SP2 with the

Domain Functional Level : WIndows 2000 mixed

Forest Functional Level : WIndows 2000 Native

We can directly migrate from Windows 2003 to Windows 2012 R2 in the same forest as well as different forest.

When we install AD on Windows 2012 R2 by default it shows DFL & FFL as Windows Server 2008 minimum level.

But still we can create the forest trusts between Windows 2003 mixed DFL/FFL to Windows 2012 R2 with DFL/FFL as Windows Server 2008

All the locations are inter-connected through MPLS & Leased Lines.

Project Scope : Consolidate 16 AD forests into the Single Forest with new name.

Created New Forest with new domain.

Added DNS IPs into the Forwarders tab into all the old AD forest DNS forwarders list to communicate with cross forests.

Even added existing domain name into the new domain DNS forwarders tab & vice-versa.

Created External Forest Trust with New Forest and with the existing 16 different forests.

Now using Profile Wizard in order to migrate the User Profile data from Old Domain to the New Domain.

This completes the cross forest migration from one AD forest to another AD Forest.

Follow the similar steps on other 15 forests.

Anand

Lync 2010 User Contacts backup before we migrate to Lync 2013 pool

Hello All Readers,

This post is about to take backup of individual users Contacts List in Lync 2010 pool. The main purpose of this post is that I was tried moving few of the users to Lync 2013 pool by selecting "Force" option under moving users from one pool to other pool.

Unfortunately one of my users contacts list got deleted or not moved successfully.

To prevent such issues it's better we take backup of Lync 2010 users in Lync 2010 Shell console as shown below:

NOTE : Backup shown below is individual user contact list backup


Start the Lync Shell with elevated rights & go to this path :
PS C:\Program Files\Common Files\Microsoft Lync Server 2010\Support>

Run this command:


PS C:\Program Files\Common Files\Microsoft Lync Server 2010\Support> .\DBImpExp.exe /user:anand@domain.com /hrxmlfile:"D:\Lync2010_User_Contacts_Bkp\20_Oct_2014\anand.xml"

Below is the screenshot:

Above shell command has taken the backup successfully.

Go to the above path, it will create the .xml file with above name.

Lync 2013 & Lync 2010 Address Book Download Issues & Find contacts issues

Hello Readers,

We normally face address book download issues and not able to find contacts in Lync 2010 client as well Lync 2013 clients.

So in that case only option is to force download the address book by using below steps:

To force the Lync Server 2013 to update the address book, execute the following cmdlet in Lync Shell on Front End :

Update-CsAddressBook

Wait for the LS Address Book Server event to report event ID 21056 listing the:

Lync 2013 :

Log off of the Lync client and delete the profile from:

%userprofile%\appdata\Local\Microsoft\Office\15.0\Lync

… then execute the following command in the command prompt to add the registry that forces the Lync client to immediately download the address book:

reg add HKLM\Software\Policies\Microsoft\Office\15.0\Lync /v GalDownloadInitialDelay /t REG_DWORD /d 0 /f


Now Log in to the Lync client & check the above path, its should create some of the files & 3 folders.

Also 2 files are created as GalContacts.db & GalContacts.db.idx which used to search for contacts under find

Now it should search for the users.

Lync 2010 :

Log off of the Lync client and delete the profile from:

%userprofile%\AppData\Local\Microsoft\Communicator

… then execute the following command in the command prompt to add the registry that forces the Lync client to immediately download the address book:

reg add HKLM\Software\Policies\Microsoft\Communicator /v GalDownloadInitialDelay /t REG_DWORD /d 0 /f


Now Log in to the Lync client & check the above path, its should create some of the files & 3 folders.

Also 2 files are created as GalContacts.db & GalContacts.db.idx which used to search for contacts under find


Now it should search for the users.



it should resolve the address book issues.

Lync 2013 WAC Issue "Sorry, PowerPoint Web App Ran into a problem opening this presentation."

Hello Readers,

Currently we are facing Powerpoint presentation issues for Lync 2013 users internal as well as external.

IM, A/V , Polling working fine

Tried scenarios are :

Lync 2010 users to Lync 2013 users: showing presentation at both sides (internal & external)

Lync 2013 users to Lync 2010 users: not showing presentation on Lync 2013 client but showing at Lync 2010 client (internal & external)

Lync 2013 users to Lync 2013 users: not showing presentation at both sides (internal & external)

Below is the error we get

NOTE : This issue occurs due to several errors as I mentioned in below link. Every time whenever you get above error, you simply need to delete the cache from below path shown in the red box.

http://social.technet.microsoft.com/Forums/lync/en-US/0bbf35a5-6518-47d4-a3ee-e756a7e87487/lync-2013-users-not-able-to-share-powerpoint-presentation-internal-as-well-as-external?forum=lyncprofile

After I made several changes in Farm & IISARR rules everything was working fine like Powerpoint presentation sharing internal as well as external.

But after 2 days I was again started getting above error while I was testing sharing Powerpoint presentation between external Lync 13 users.

This issue occurs due to Caching of powerpoint files on Office Web Apps server below path as shown:

Followed this link : http://lynclounge.blogspot.in/2014/07/lync-2013-wac-issue-sorry-powerpoint.html

Special Thanks to Anthony who helped me to resolve this issue.

First stop the Office Web Apps Service on Web apps server & Simply go to the above path & delete or move the data to other path if you need.

Now start the Office Web Apps Service & try to share the PowerPoint presentation files which we get errors.

Now it should work fine without any issues.

Mine Powerpoint presentation sharing is working fine.
