We are testing IE10 with CRM 2011 Update Rollup 13 (on premise), mainly to get the spell checking feature. So far, using IE10 to hit CRM directly, the spell checking works. However, the spell checker does not work when using the Outlook client to hit CRM. Pulling up an Account directly in IE10 - spell checker works; pulling up the same Account through Outlook - no spell check even though the form is being shown through an IE window. I'm also seeing some style differences on the forms between the Account form pulled up directly in IE10 vs the Account form pulled up through Outlook, as though Outlook is running the IE10 pages in compatibility mode. Could that be what's removing the spell checking?
Has anyone seen the same problem and come up with a solution?
