InternalServerError when making PullSubscription with SubscribeToAllFolders - soap

Question

I'm trying to use the PullSubscription with the SubscrubeToAllFolders attribute as documented on the Microsoft Office Dev Center:
<?xml version="1.0" encoding="UTF-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
<s:Header>
<t:RequestServerVersion Version="Exchange2013_SP1" />
</s:Header>
<s:Body>
<m:Subscribe>
<m:PullSubscriptionRequest SubscribeToAllFolders="">
<t:FolderIds />
<t:EventTypes>
<t:EventType>CopiedEvent</t:EventType>
<t:EventType>CreatedEvent</t:EventType>
<t:EventType>DeletedEvent</t:EventType>
<t:EventType>ModifiedEvent</t:EventType>
<t:EventType>MovedEvent</t:EventType>
<t:EventType>NewMailEvent</t:EventType>
<t:EventType>FreeBusyChangedEvent</t:EventType>
</t:EventTypes>
<t:Watermark />
<t:Timeout>1</t:Timeout>
</m:PullSubscriptionRequest>
</m:Subscribe>
</s:Body>
</s:Envelope>
However this will always return an ErrorInternalServerError with text An internal server error occurred. The operation failed. and no faultactor. I've tried this with and without the superfluous <t:FolderIds /> and <t:Watermark/> tags. With different timeouts and different contents of <t:EventTypes>.
But when I remove the SubscribeToAllFolders="" and add in the folders manually like:
<?xml version="1.0" encoding="UTF-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
<s:Header>
<t:RequestServerVersion Version="Exchange2013_SP1" />
</s:Header>
<s:Body>
<m:Subscribe>
<m:PullSubscriptionRequest>
<t:FolderIds>
<t:DistinguishedFolderId Id="inbox" />
</t:FolderIds>
<t:EventTypes>
<t:EventType>CopiedEvent</t:EventType>
<t:EventType>CreatedEvent</t:EventType>
<t:EventType>DeletedEvent</t:EventType>
<t:EventType>ModifiedEvent</t:EventType>
<t:EventType>MovedEvent</t:EventType>
<t:EventType>NewMailEvent</t:EventType>
<t:EventType>FreeBusyChangedEvent</t:EventType>
</t:EventTypes>
<t:Watermark />
<t:Timeout>10</t:Timeout>
</m:PullSubscriptionRequest>
</m:Subscribe>
</s:Body>
</s:Envelope>
I get the expected response.
Anyone had any problems with SubscribeToAllFolders before? Is there a way to get it working? I'm relatively new to EWS and SOAP so am I doing anything definitively stupid up my end? Thanks for any help.

Your request isn't formatted correctly eg it should look like
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
<t:RequestServerVersion Version="Exchange2013_SP1" />
</soap:Header>
<soap:Body>
<m:Subscribe>
<m:PullSubscriptionRequest SubscribeToAllFolders="true">
<t:EventTypes>
<t:EventType>CopiedEvent</t:EventType>
<t:EventType>CreatedEvent</t:EventType>
<t:EventType>DeletedEvent</t:EventType>
<t:EventType>ModifiedEvent</t:EventType>
<t:EventType>MovedEvent</t:EventType>
<t:EventType>NewMailEvent</t:EventType>
</t:EventTypes>
<t:Timeout>5</t:Timeout>
</m:PullSubscriptionRequest>
</m:Subscribe>
</soap:Body>
</soap:Envelope>
I'd suggest you look at using the EWSEditor https://ewseditor.codeplex.com/ to do some testing it will both let you test the operation and give you the SOAP used for each request and response.
