"an unknown error occurred, error code 0x8000ffff" - OUTLOOK 2016
Posted on 2016-09-09
Running Outlook 2016 on Windows 10. Outlook originally connected to the Office 368 link and synced up as expeted, but due to license issues, had to basically removed the installed OFFICE suite and use an ISO version and then an activation key - which worked and Word, Excel etc are all working
Outlook complains that "The MS Exchange Information service in your profile is missing required information. Modify your profile to ensure that you are using the correct MS Exchange information service"
I have been into Control Panel, Mail , Data Files. I am unable to remove the Data File which was added when it connected to the Office365 profile. It says the data file is associated with a mail account. To remove it use the E-Mail Tab. Try under that, says I must create a new data location for your data. so under Data Files click ADD.
Which when I click ADD returns "an unknown error occurred, error code 0x8000ffff"
I could add another e-mail which was my hotmail address and this worked but I am still unable to remove the legacy OFFICE365 mailbox/data files. This is stopping me run OUTLOOK 2016 and then I need to re-connect to Office 365 as I now have an activated version of the product.
