Really in a hole here.
I have an SBS2008 box with Exch2007 and W7 pro workstations (couple of XPpro too)
I was advised that I could co-exist the local Exchange 2007 with a Hosted Exchange 2010 server as an interim solution while migrating to full Hosted Exchange 2010.
I had even created a test installation on one of the workstations with two Outlook 2010 profiles, one for Local Exchange one for Hosted Exchange. This appeared to work and so confirmed the advice.
I am now advised that the AD and integrated SRV records in SBS2008 will continually pull any attempted connection to an external Exchange account into the local Exchange. Indeed upon further inspection of my test installation the External connection now fails to login correctly even though I know the credentials are correct.
I have 15 new users who must have new email accounts by 16 January and we were planning to migrate a similar numer of existing accounts from the SBS2008 box to Hosted Exchange for one domain. Other domains would need to stay on the SBS Box for a while (few weeks) while we managed a migration plan.
Can anyone confirm that this co-existence is not possible - or preferably how I can get out of this mess by some workaround.
If further clarification is required would appreciate a switf email.
Will be back to this problem in a couple of hours.
Thanks in advance
