Outlook 2013 and Lync 2013 suddenly cannot run at the same time

If you’ve made the switch to Office 365 you may have had a relatively smooth ride since the they’ve moved things to Exchange 2013 and Office 2013. That said, nothing’s ever all roses all the time, am I right? Today a customer experienced an issue where suddenly Lync 2013 is no longer able to launch and shows an error about the Outlook Datafile being inaccessible. Here’s how to fix the situation:

[the problem]

Lync 2013 displays this error on startup: Outlook Data File: The file <filename> is in use and cannot be accessed. Close any application that is using this file, and then try again. You might need to restart your computer.

[the solution]

[step 1] Close all Microsoft Office applications including Outlook 2013 and Lync 2013.

[step 2] Open the task manager to make sure all Microsoft Office processes are terminated.

[step 3] Click Start->Control Panel->Programs and Features and highlight Microsoft Office 365. Click Change. Select Quick Repair and then click Repair.

NOTE: if asked to close all programs, click Close All.

[step 4] When the repair is complete, open Outlook 2013, then Lync 2013 to see if the error has been resolved.

[troubleshooting]

  • If the above steps haven’t resolved the issue, try theĀ Online Repair instead of the Quick Repair.
  • If the Online Repair doesn’t resolve the issue, re-create the Outlook email profile.
  • If re-creating the MAPI/Outlook email profile doesn’t work, run the Office 2013 removal fixit tool [download here http://support.microsoft.com/kb/2813143]. Then re-install Office 2013.

That’s it.

    Cannot open Outlook when Lync is running.
    I am trying to do a repair of my Office 365 as recommended, but when I go to Control Panel and then click on Programs and Features, I cannot find Office 365 listed there

      Uninstall Office using the removal fix-it tool and install it again. Then you should be able to see Office in Programs and Features. Then run the repair.
