  • Hi Avyan,

    Does this issue persist all the time on this site? Or what do you do before this issue happened?

    Except deleting the cache file, it also needs to delete your sign-in info as the below image shows.

    If it is still no luck, you can try to repair an Office application on the problem machine by this link: https://support.office.com/en-us/Article/Repair-an-Office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b.

  • Hi Avyan,

    What kind of users meet with this issue? Internal users or users logging in from Internet.

    If the internal users have this issue, it recommends you check if there is any related error message in Lync server event viewer on front end server of this site.

    If the users logging in from Internet have this issue, it recommends you check if there is any event ID in Edge server.

    Moreover, you can test the connectivity of your environment by this tool: https://testconnectivity.microsoft.com/.

  • I took a network trace and found that when this issue happens , the  TCP packets from client are not reaching the server . So have involved the network team.
