Outlook was previously connected to local Exchange Server (2003) but this is not on the Network anymore and Outlook account deleted.
Within the last week I have been using online exchange. On 3 machines running Win XP (SP3) with Office 2007 (also SP3) I get the following when I try to connect to the Online Exchange system;
'The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must bee online to complete this action'
However, on the same network, I have two machines with Outlook 2010, one on XP, one Win7 which connected no problem.
Here's what I have done to try and resolve the problem
1) Have ran offive 365 online machine software check. Two updates were applied with note that Outlook should me connected manually (which is basically to use autodiscover).
2) Have created new profile
3) Have aplied Microsoft Knowledgebase fix 913843 (which actually I don't think is applicable to an Oline Exchange connetion)
4) Have ran Microsoft Autodiscover check which reported Test Passed (but with some warnings)
5) Have temporarily opened all ports on firewall
I note that many people seem to be having same problem
All successfully logon to online OWA no problem
Has anyone actually resolved this problem?
