Exchange Calendar Permissions Using PowerShell
Exchange Calendar Permissions Using PowerShell
With Exchange 2010 and now extended into Exchange 2013 and 2016, Microsoft added the ability to manage permissions on folders in a users email account through PowerShell.
The most common is managing calendar permissions. Heres an example of some commands:
To get the permission on a mailbox:
Get-MailboxPermission -Identity "Boss Hog"
To get the permissions of a subfolder:
Get-MailBoxFolderPermission -Identity "Boss Hog:Calendar"
To change permissions on a subfolder:
Add-MailboxFolderPermission -Identity "Boss Hog:Calendar" -user "Roscoe" -AccessRights Reviewer
To remove permissions on a subfolder:
Remove-MailboxFolderPermission -Identity "Boss Hog:Calendar" -user "Roscoe"
Heres also a list of all of the permissions you can assign. HERE is a link to Office support with some details on what each of these permission levels can do.
- None
- Free/Busy
- Free/Busy, Subject, Location
- Contributor
- Reviewer
- Nonediting Author
- Author
- Publishing Author
- Editor
- Publishing Editor
- Owner
Hopefully this will give you some assistance when you need to edit calendar permissions without the need to login as that user account and then use Outlook to make the edits. Granted thats the GUI route but this works best from an Exchange administrators perspective.
Good luck!

Discover FSMO Roles Using PowerShell
Discover FSMO Roles Using PowerShell
Working with a rather confusing AD setup recently and trying to remove a dead domain controller I needed a quick way to identify which machines had the FSMO roles.
Just run the following commands:
This gives a nice quick output as to where the roles reside and allows you to capture them as needed.Get-ADForest| Format-Table SchemaMaster,DomainNamingMaster Get-ADDomain| Format-Table PDCEmulator,RIDMaster,InfrastructureMaster
If you want to manage the roles with PS the command to move the roles is Move-ADDirectoryServerOperationMasterRole and it can be used in a variety of ways.
To transfer all 5 of the FSMO roles simply run the following command in PowerShell:
Move-ADDirectoryServerOperationMasterRole -Identity “Target_DC_name” –OperationMasterRole PDCEmulator,RIDMaster,InfrastructureMaster,SchemaMaster,DomainNamingMaster
To shorten the command line syntax you can use role numbers in place of the role names. The following list details the role number for each of the five FSMO roles.
- PDC Emulator – 0
- RID Master – 1
- Infrastructure Master – 2
- Schema Master – 3
- Domain Naming Master – 4
So if you wanted to transfer all 5 FSMO roles using numbers instead you would run the following command in PowerShell:
Move-ADDirectoryServerOperationMasterRole -Identity “Target_DC_Name” –OperationMasterRole 0,1,2,3,4
Now in my case since the DC was gone permanently I had to seize the roles using the –Force parameter. This is the PowerShell command I ran to seize the roles:
Move-ADDirectoryServerOperationMasterRole -Identity “Target_DC_name” –OperationMasterRole PDCEmulator,RIDMaster,InfrastructureMaster,SchemaMaster,DomainNamingMaster -Force
Of course I could have used the short version:
If you are just transferring or seizing a single role you will run the same command with just the name(s) or number(s) of the role(s) you want to move. These commands can be run from any Windows Server 2008 R2 or newer as well as Windows 7 or newer with RSAT tools installed.Move-ADDirectoryServerOperationMasterRole -Identity “Target_DC_Name” –OperationMasterRole 0,1,2,3,4 -force
This is a little better than running all over the AD tools to get everything moved over.
Good luck.

Backup Cisco Configs Using Putty
Backup Cisco Configs Using Putty
You can easily capture the configuration file from any network devices like Cisco Routers, Switches etc.. with putty. Follow below steps..
1. Launch putty and connect to your Cisco router/switch
2. Enter the user exec mode (router> enable)
3. Enter the terminal length 0 command (router# terminal length 0) in order to force the router to return the entire response at once, rather than one screen at a time. This allows you to capture the configuration without extraneous ??more?? prompts generated when the router responds one screen at a time.
4. Right-click on the menu bar of the Putty screen and select “Change Settings”
5. Go to Session and click on Logging, select “Log all session output”
6. Click on Browse and choose the location and name of the file (I like to place my config file on my desktop – C:Documents and SettingsAdministratorDesktopconfig.txt)
7. Click apply.
8. Now enter the show run command (router# show run), then log out and see the output in config.txt on your desktop (or the location you chose).
This is a pretty simple thing to do and can be a real life saver if you happen to lose the config on a device. It sure is a lot easier to copy and paste it back in instead of recreating it from scratch. Cisco equipment is great but I have seen instances where the running config wasnt saved to the memory and after a restart it reset back to an old startup config or back to brand new (worst case).
You now have the power!

Archive Cisco Switch and Router Configs Using TFTP and Configuration Archive
Archive Cisco Switch and Router Configs Using TFTP and Configuration Archive
The worst time to realize you dont have a current backup of your switch or router is when that device is having issues or worst case dies and it is actually needed. For a great comprehensive list of Cisco IOS commands I recommend THIS BOOK. Its for Amazon Kindle.
Administrators have the ability to run a manual backup of the configs or you can set it to do this automatically or every time you do a "write memory" to save a config change.
Given how easy this is to setup theres no reason for you not to have this on your switches.
Lets dive into how easy this is to setup.
First youll need a good TFTP server program. Personally I like the free Solarwinds TFTP Server. This like is for the Windows version. You can run it on a server or a workstation if needed. The price is right, setup is simple, and youll have this going in a couple of minutes.
Next its time to setup the switch or router to do the automatic backups for you.
Lets look at a couple of way to set this up.
The first way is to just backup each time you do a "write memory". This is my favorite setup as it does not generate unnecessary network traffic and I know that the files on my TFTP server are the latest config as long as they were saved.
R1(config)#archive R1(config-archive)#path tftp://192.168.1.10/R1-config R1(config-archive)#write-memory R1(config-archive)#exit |
Now one of the details I add after the IP address and forward slash is the name of the device so when it creates the automatic backup file I know which device it came from based on the devices host name.
Another way to set this up is to do backups daily for you automatically without the need to a manual update. This setup will archive every day or if you do a "write memory" command on the switch.
R1(config)#archive R1(config-archive)#path tftp://192.168.1.10/R1-config R1(config-archive)#write-memory R1(config-archive)#time-period 1440 |
Now these two methods ensure your switch configs are backed up either as you do a change and save it or automatically each day.
Finally the great thing about these auto backups is you can also restore them using the same functions. One thing to note is that this command does not merge the settings with what is currently running, it fully replaces it so use caution.
