Using Outlook 2016 Keep getting this message when I login into Outlook RRS feed

  • Question

  • When I log into Outlook 2016 after a short time I get the following message comes into  Sync issues folder. normally I finish up with about 3 notices  

    at  different times. I delete them but when I login again they are back. I have looked everything on Sync issues concerning (0x80004005  notice and have tried one or two attempts but I am unable to stop the sync problem.

    All my files are in order and download ok but would like to no if this can be stopped as it is getting annoying.

    When I go into    support  as suggested on this notice there is no information there.

    Thank you for any help.

  • Hi Richard,

    Do you have a folder named '8f4d1315-5cf9-4621-9872-b1b94618e70a' in your mailbox? Do you have any internet calendar subscribed? If any, please try temporarily disabling the syncing and then see whether this issue continuous.

    Besides, please also try starting Outlook in safe mode (outlook /safe) to see the result. This helps determine whether this issue could be caused by problematic add-ins.

    Regards,

    Steve Fan

  • Solved by renaming the .ost file. Outlook is making a new standard .ost file automaticaly and syncing start from scretsh without probrlems.
