Runtime Exception When Using Set-OrganizationConfig

Rhys Pickett 40

Trying to run Set-OrganizationConfig cmdlet in powershell EXO V3 module returns runtime exception: "unable to find type [uint]". Has anyone had this error before and know of a potential solution? I cannot find anything online to reference this.

I can run Get-OrganizationConfig absolutely fine. I can see other topics with people being able to run the get cmdlet and not the set cmdlet - their solution was permissions based. I have checked my permissions and I am part of the Compliance Administrators group and also I am a part of the tenant admin group, so I think permissions should suffice for what I'm trying to achieve here.

Many thanks for reading - any help greatly appreciated

Hey Rhys,

There are few things you can try.

Check if you have the same issue with a confirmed Global Admin.

Check your execution policy. You can use "Set-ExecutionPolicy Bypass -Scope Process" to temporarily bypass the policy within the scope of your current PowerShell session.

Make sure you have all dependancy modules installed and imported.

I'm not sure what parameter you are trying to set. But it could be a type mismatch in your command when setting the value for one of the attributes in the command.

If you can give us more insight in the attributes/parameters you try to run the command with, we could identify the issue more clearly.

Hope this helps you to resolve your issue.

Hi Karelpelck, many thanks for your reply.

I can confirm that my account is global administrator level (when checking in Entrana roles). I connect to ExchangeOnline using these credentials and still receive the error message.

I have also tested with Set-ExecutionPolicy Bypass -Scope Process as advised but still the same error message unfortunately. I have also tried Set-ExecutionPolicy unrestricted with no luck.

From the 2 below links, It appears that only the ExchangeOnlineManagement module is required to run this cmdlet (unless I am mistaken) and can confirm this is present on the machine. This module allows me to run Connect-ExchangeOnline to gain access to our tenant initially.

https://learn.microsoft.com/en-us/powershell/module/exchange/set-organizationconfig?view=exchange-ps

https://learn.microsoft.com/en-us/powershell/module/exchange/?view=exchange-ps

With the 2 above links also, the parameter values I'm passing through look to be accepted. Here is the cmdlet I am trying to run:

Set-OrganizationConfig -MailTipsAllTipsEnabled $true -MailTipsExternalRecipientsTipsEnabled $true -MailTipsGroupMetricsEnabled $true -MailTipsLargeAudienceThreshold '25'

Interestingly, I also receive the same error message when running 'Set-OrganizationConfig' on its own with no parameters.

I'm a bit at a loss with this one with myself being global administrator. I have also tested on multiple machines but still the same error message - so the issue does seem specific to the environment. Is there anything else I can try and check on?

Many thanks

Hey Rhys,

I have been using the PowerShell 7 version for a while now. And could not reproduce this issue running it with PowerShell 7. When I tested on Windows Powershell (Version 5.1) I got the exact same error as you described.

I would install PowerShell 7 and run it with this version. I'm assuming here that the type "uint" is not build into Windows PowerShell. I could not find any direct documentation that explains this to provide for you.

If you are using PowerShell 5.1 and 7.X side by side, you might want to look into Windows Terminal as a Command Line tool as well as Visual Studio Code.

Yes, can confirm it works with 7. What's weird is that I know it worked before

Thanks Karelpelck/Andy! I suspect this may be the issue then! :)

I will give PS7 an install now and will confirm your response as answer if all OK and working. A very quick turnaround on this issue so honestly, I really appreciate this thank you both for your time.

I had forgot to include that piece of information so apologies for that! turns out to be the most important part haha :D (for reference I like to use powershell_ISE when Im running commands, which I believe is not available in V7 so I will have been using 5.1)

I can confirm using PS7 works - I've marked the original answer and accepted (not sure how to convert your PS7 comment to the right answer but hopefully that should be OK for anyone also stumbling across this article)

Thanks again both, have a great day.

This is not a solution, sure running later version of PS might be a workaround, but in many cases it won't be.

Someone else mentioned using the console in exchange admin web, which might be a different workaround, but still not a fix.

This needs to be addressed in the source since it is a clear bug.

PowerShell 5.1 doesn't understand the abbreviated "uint" type. It never has. You can use "uint64", "uint32", or "uint16".

"int", for example, is a type "accelerator". It isn't a "real" type. "Int32" is a real type. But there's no "uint" type accelerator.

@Andy David if that worked before it was probably a change in the cmdlet, not PowerShell, that caused the problem.

Looking at the Set-OrganizationConfig help, I only see "Int32" types. Knowing what values were fed to the cmdlet might help (maybe),

The cmdlet code has this:

[uint] ${MailTipsLargeAudienceThreshold},

Which means this is a bug that needs to be fixed in the code generated from Connect-ExchangeOnline
I think this worked when I connected yesterday, so it seems to be a recently introduced bug.

The online help says that parameter is an optional value of type Uint32.

I don't have any Exchange organization cmdlets to look at this, but someone should run Get-Help Set-OrganizationConfig -Parameter MailTipsLargeAudienceThreshold and, if it reports the object type "uint", that bug should be reported!

This is a bug (unless the requirement of PS version has changed) the only question for me is where the correct place to report it is, If I knew there was a git repo for it, I would even open a PR to have it fixed, but Microsoft is a bit lacking in information about sources for their cmdlets.

uint is most likely an alias for UInt32, valid in newer versions of C#, we don't have to check what the command gives, because we have already seen what it errors on, and what the script contains, it has uint, which is not valid in older versions of PS, this is an error in the cmdlet code, and is not impacted by any variable or similar on client side.

I haven't worked with Exchange for ten years (retired) and I no longer have any access to Microsofts' support folks (I was and Exchange MVP for 16 years). However, MVPs have that access, and I'd start there. The only name that comes to mind from my time as a MVP is @Andy David -- let's see if tagging him gives him a poke.

The "uint" type accelerator is valid in Powershell 7 -- but NOT in PowerShell 5.

"uint" in PowerShell 7 is the same as "uint32".

So, yeah, clearly a bug. No argument there.

I've been fighting with this issue for over an hour. Discovered this thread, installed Powershell 7, and everything worked fine. Do with that what you will...
