Deleting specific files from Sharepoint on-premises library

Starting from this request, bellow you will find the script needed to try 2 option

The first one , the Powershell script will read the csv file and for each entry, fill parse the SharePoint library for the file

The second one, will use CAML queries to locate the specific file

For both of them, the measure command will show the time needed to resolve the requests.

Even for small libraries you will see that the second option is faster.
For large libraries and for long csv file, it is recommended yo use queries.

This script can be useful to search specific files in sharepoint on-premises, in a specific site.
The files are located in the csv file. The mandatoryy parameters are:
– $SiteUrl     : the URL for the site
– $LibraryName : the library where the files are located
– $Filename    : the csv which contains the files
The files in the csv files need to be with the full url
If the site is the root site , you can use $myweb and $mylist variables
This script can be use as it is or can be changed based on your needs. For more details please feel free to contact me

Backup site collections from a .csv file using Powershell

Assuming that you have a .csv file which contains a list of site collections in this format


the line you need to backup them is this one:

ImportCsv yourfile.csv | ForEach-Object { Backup-SPSite $_.URL -Path $_.path -force}


But what if do you have only site’s URL? and the csv file looks like:


In this case you need to use URL to get the .bak file name

ImportCsv yourfile.csv | ForEach-Object { Backup-SPSite $_.URL -Path (($_.Url).replace(“/”,”).replace(“:”,”)+”.bak”)  -force}

where ($_.Url).replace(“/”,”).replace(“:”,”)+”.bak” will be the name of the backup file like this one

To avoid overwriting, you could add datetimestamp in file’s name like this

Import-Csv yourfile.csv | ForEach-Object { Backup-SPSite $_.URL -Path (($_.Url).replace(“/”,”).replace(“:”,”)+”_”+(Get-Date -Format “yyyyMMddhhmm”)+”.bak”) -force

and the back-up file will looks like:

Sum of time values for two DateTime columns

Starting from this post let’s suppose that your two DateTime Columns are


and the request is to sum the time values. The final value  ( as a text ) will be in this format hh:mm.
For this you will need to create a calculated column and there to insert the final formula

Bellow are presented each step, one by one. Based on your regional settings, could be necessary to replace “;” with “,” in final formula ( Step 3. )

Step 1. Hours

The easiest part is to add hours, and the formula for this is

What about minutes? The easiest  way –  add minutes from both columns

But what if this value exceed 60? This mean an hour at least. Well in this case the formula:

So, the numbers of hours will be:

Add domains in Office 365 with Powershell

If you would try to add a new domain to your Office 365 tenant , using Powershell, the steps are ( of course after you install Windows Azure Active Directory Module for Powershell )

Step 1. Connect to your tenant
Get-MSolDomain ( this is just to verify which domaains are already attached to your tenant )

Step 2. Create a new Domain
New-MsolDomain -TenantId “customer_TenantId” -Name “FQDN_of_new_domain”

Step 3. Get domain verification key
Get-MsolDomainVerificationDNS -TenantId “customer_TenantId” -DomainName “FQDN_of_new_domain”

Step 4. Modify your DNS and wait for replication

Step 5. Confirm the domain
Confirm-MsolDomain -TenantId “customer_TenantId” -DomainName “FQDN_of_new_domain”

So far so good

But my question is:
Why a similar parameter ( Domain name ) use different names in these cmdlets ( -Name versus -DomainName )? Check Step 2 versus 3 and 5.

A complete Microsoft document about the procedure can be found here.

Le roi est mort, vive le roi!




Because public sites on SharePoint Online will be not anymore supported starting to first of April 2017, some changes will arrive.

The new domain is here !

The old one is still running on the old platform and it will be redirected to .com

All pots are migrated, but some customizations can arrive in the next days. The link to the photo and  lme sites are not working for the moment.

Comments, suggestions and any details are welcome!
