This error is often caused from the BITS job list being full, to fix this, you must clear/reset the BITS job list. Microsoft outlook uses BITS to download Offline
address book and if the BITS queue goes full it stops.
The resolution is to run the following command to clear the transfer queue.
Open
Run and type the following command there
bitsadmin.exe /reset
If the user doesn’t have access to run this you can run the following command as an administrator:
bitsadmin.exe /reset /allusers
After running the above command Restart the System and update the address book
Thank You!
