Exchange Online - Set max message transport size

Weird thing, makes me pull hair out in chunks.

I have a private internet mail account using POP. I use the same Outlook client to connect to a hosted Exchange email account for business. Different domains and addresses.

When I attach a file to my POP email draft it warns me that "the attachment size exceeds allowable limit".

I notice that the draft that is to be sent from my POP account also appear in OWA under drafts. Hence I figured that this has to do with the max transport settings in the hosted Exchange as my ISP for the POP account has no limits anyway.

When I try to figure out how to change the max size however I am going around in circles. I have configured Powershell but cannot find the command to do it via this. Equally the Admin console on Exchange 365 does not offer any options.

Does someone have a quick way or even a link to a step by step that helps me out here?

Many thanks
capt.

The powershell commands you need are:

Get-RoutingGroupConnector | Set-RoutingGroupConnector -MaxMessageSize xxMb

Identify the connectors you have access to and change the limits accordingly (if you have access to do so).

Access should not be the problem.

I will try this and get back to you.

I have connected to the online host successfully using this kb:
http://help.outlook.com/en-us/140/cc952755.aspx

But I am getting the following error:
The term 'Get-RoutingGroupConnector' is not recognized as the name of a cmdlet, function, script file, or operable prog
ram. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

What is the issue here?

Are you trying it in Exchange Management Shell or regular PowerShell?

Oh - and what Exchange version?

It is the Hosted Exchange Online 365, not on-site. So I use Powershell as described in the linked kb.

I don't think you can get EMS unless you have an Exchange Server on site...

You have to download the cmdlets and then from powershell import the module msonline

Hello,

You can't set this in Office 365. Microsoft sets a limit of 25MB.

Thanks for both answers. So JJ what you are saying that I cannot set this even if I install cmdlets?

Jamie McKillopCommented:
That is correct. You are not able to modify this value in Office 365.
