My SRV record is: -

_autodiscover._tcp 5 443 {domain}.co.uk. (with the '.' at the end) and I don't have any problems.

Think your SRV record may be wrongly formatted.

How to use the new DNS SRV lookup method to locate the Exchange 2007 Autodiscover service

To use the new DNS SRV lookup method in order to locate the Exchange 2007 Autodiscover service, follow these steps.

Note You must create the Autodiscover SRV record in the external DNS zone that matches the right side of your user's SMTP addresses. For example, if a user's primary SMTP address is user@contoso.com, the record must be created in the contoso.com external DNS zone. If you have multiple primary SMTP address domains in your organization, you must create an Autodiscover SRV record in each zone...

etc..etc..etc..
