Hello all.

I have 2 CAS and 2 mailbox Server with Exchange 2013 CU9 installed.

Even with TMG publishing OWA logoff procedure worked fine.

So I have Basic and integrated windows authentication on OWA and ECP virtual catalogs.

But after I integrated Lync 2013, IM in OWA works fine but OWA Logoff stopped working even inside the network... IM in OWA works as expected.

Any ideas guys?

Hi Garrett,

Thank you for your question.

Did the issue occur on external users?

Did you use the different browsers to check if the issue persist?

Is there error when we click Logoff?

We could restart IIS to check if the issue persist. For testing, we could change OWA to default authentication to check if the OWA work.

In addition, we could check if there are any errors in application log.

If there are any questions regarding this issue, please be free to let me know.

Best Regard,

Jim
