[PS] Writing errors and output to a text file
|
1 |
.\MyScript.ps1 2>&1 | tee -filePath c:\results.txt |
Explained:
tee (tee-object) cmdlet redirects output into two directions, stores in a file or var and sends down the pipeline. In our use, it sends to a file and also displays on console.
2>&1 construct, (stderr) 2> redirects the standard and appends the &1 (stderr to stdout) to a filename of results.txt.
Other constructs.
stdin – Standard input = 0
stdout – Standard output = 1
stderr – Standard error = 2
> – Redirect pipeline output to a file,overwriting the current contents.
>> – Redirect pipeline output to a file,appending to the existing content.
2>> – Redirect error output to a file,appending to the current contents.
2> – Redirect error output to a file,overwriting the current contents.
2>&1 – The error messages are writtento the output pipe instead of theerror pipe.
Supports PS 1.0,2.0
Supports PS 3.0+; captures only standard output

[EXO] Enabling Mailbox on Exchange Online Hybrid Configuration (ADFS)
Enabling/Creating a Mailbox on Exchange Online in a Hybrid Configuration (ADFS)
Considerations:
- Retention policy must be applied on the Exchange Online instead of against the on-premises AD object.
Use the New-RemoteMailbox cmdlet to create a mail user in the on-premises AD and also create an associated mailbox in Exchange Online.
Enable-Remote Mailbox is for an existing AD user.
- remoteRoutingAddress needs to be specified to point to cloud
- Forwarding would be set on the cloud mailbox using the cloud connection

[PS] Parameter with validation
Master powershell’s extensibility’s use of functions is key real life application of PS scripts. Parameters are primarily known as input functions, where information can be passed and validated. Below is an example of how of passing a parameter and setting static validation sets:

1 2 3 4 5 |
Param( [parameter(Mandatory=$true)] [ValidateSet("Low", "Average", "High")] [String[]]$Detail ) |
