But if that's not the case, I'm wondering if I can't just do the Exchange 2019 upgrade now and keep dealing with the Office 2010 issue as we get funding availalble.If you are continually being prompted for your password in Outlook try the steps below, one at a time, to resolve the issue.

In the meantime we have been delaying our upgrade to Exchange 2019 because we were assuming that all Outlook 2010 would immediately stop as soon as we upgraded. Does anyone have any information on this? Is there something I'm not noticing that is clearly not working? I find it strange that I can't find anything online relating to 'It's not supported, but it still technically works'.Ĭouple side notes: We have hundreds of computers with Office 2010 still, we are working on getting them upgraded, but management is slow to dish out the money to get this done. It seems to be fully functional as best I can tell as well. However I just tested Outlook 2010 out of curiosity today and it connected to Exchange 2019 CU 5 without issue. What I'm curious about though, is that Microsoft says that Outlook 2010 WILL NOT work when connecting to Exchange 2019, and everything else I've found online seems to agree with this.

Before I start - I am FULLY aware that this is not supported by Microsoft.
