--- Comment #5 from Carl Schwan <c...@carlschwan.eu> --- Do you maybe have a the body of one of the EWS request with an invalid ID? Locally I get: org.kde.pim.ews.client.proto: "<?xml version=\"1.0\"?><soap:Envelope xmlns:soap=\"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\"><soap:Header><t:RequestServerVersion Version=\"Exchange2007_SP1\"/></soap:Header><soap:Body><m:GetItem><m:ItemShape><t:BaseShape>IdOnly</t:BaseShape><t:AdditionalProperties><t:FieldURI FieldURI=\"item:MimeContent\"/></t:AdditionalProperties></m:ItemShape><m:ItemIds><t:ItemId Id=\"AAMkADgzNzkyOTg1LWZmYzgtNDY3Zi1hMjU2LTFlODNlZGIxNTVlNgBGAAAAAACGij6e2qxSSoxGqEgp0YQIBwAQB6nxUL4fQLR2Ugu0H+JMAAAAAAEMAAAQB6nxUL4fQLR2Ugu0H+JMAATIyE6cAAA=\" ChangeKey=\"CQAAABYAAAAQB6nxUL4fQLR2Ugu0H+JMAATLClcH\"/></m:ItemIds></m:GetItem></soap:Body></soap:Envelope>\n" and this is valid according to Outlook/Office365. -- You are receiving this mail because: You are watching all bug changes.
