Hello,

We are having issues where users are not able to use the edit in out look feature. It will first say that microsoft outlookc is not available, then this error pops up.

    Hello,

    Verify the permissions of the NST user within that folder.

    Thanks.

    Hello,

    This was a really weird one, but after some time messing around with it, it seems the simple (I know not preferred) solution below worked for us.

    uninstall NAV

    uninstall Office

    reinstall Office

    reinstall NAV

    Regards,

    I had the same problem, but on a Citrix environment. We tried to reset the Citrix profile for the user and that worked for a month, then the exact problem occurred again. We looked into the code without really finding anything except it just returned false when trying to initialize the NewMessage function in Outlook.

    We eventually switched from the 64 bit exe file to the 32 bit exe file and that solved the problem instantly.

    Regards,

    Hi, It still looks like it can't find the file or doesn't have permission to access the folder.
    It is recommended that you reinstall NAV, and then try again after confirming the permissions.

    Hope this helps.

    Thanks.
