Lync 2013 login issue

Hi

Lync 2013 32 bit has installed in two systems(Windows 7 64 bit and Windows 8.1)First time when the user  in the system lync will get sign-in.But after sign out it will give the error sayin" Can't sign in to lync,The user name password or domain appears to be incorrect Ensure that you entered them correctly.I checked the username,password email address everything correct..

When i close and reopen the lync it will get sign in without issue

Any solutions

Hi,

please check that SIP and UPN is the same.If not you will have to click advance and enter username domian\username and password.

If SIP and UPN is the same this is not needed,only "sip" address is required.

If SIP and UPN is the same,then there is no need to enter domain\username.

After Outlook starts,you might need to enter another credential.If sip,upn and smtp is the same then it should be fine.

Hi Rajith.M,

Please check if the time is set incorrectly on the computer.

In addition, you can try to recreate the user profile.

 

Delete following user data. 

User profile:

%userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\sip_UserName@Domain.com

 

Registry Key:

HKCU\Software\Microsoft\Office\15.0\Lync\UserName@Domain.com

 

Best regards,

Eric
