Sign up for Office 365
Learn more about Office 365
I have recently started a trial of Office 365, all is well apart from this issue with Lync 2010.
On any PC i have tried so far, I cannot sign in to Lync 2010 with the one default account.
"Cannot sign in to Lync
There was a problem acquiring a personal certificate required to sign in. If the problem continues, contact your support team."
I have downloaded and re-installed Lync 2010 and Office Desktop Apps Setup multiple times now, along with updating the Windows update for Lync 2010 when the Desktop Apps finished installing.
I removed the EndpointConfiguration.cache file before a few sign in attempts.
Followed this KB article advising to delete any certificates or crypto RSA key container i do no currently have. Last but not least i checked credential manager for any incorrect saved details, nothing to remove there.
Really at a loss with something that appeared so simple upon sign up.
Can anyone help ?
Thanks for the feedback.
Hi HCS Matt,
I am glad to hear that everything is working. It was a pleasure helping you and have a great day.
Thanks Brent Coldewey
Hi HCS MAtt,
Please try the following steps:
1. In the upper-right area of Lync 2010, click the Gear icon to open the Options page.
2. In the Lync - Options dialog box, click Personal.
3. Next to the sign-in address, click Advanced.
4. Make sure that Manual Configuration is selected and that the configuration values are exactly as follows:
Internal server name or IP address: sipdir.online.lync.com:443
External server name or IP address: sipdir.online.lync.com:443
5. Try to sign in Lync.
Sorry, i should of said i saw that post and also tried the manual address before i posted this.
Thanks very much, i tried again out of hope but it didn't work again this morning trying those 2 methods.
Hello HCS Matt,
Do you mean that when you tried signing in Lync as one default account, you encountered the following error message?
“Cannot sign in to Lync
There was a problem acquiring a personal certificate required to sign in. If the problem continues, contact your support team.”
If so, please refer to the following steps to narrow down the root cause of the issue.
1. Test whether the same issue occurs on other users’ accounts that are in the same Office 365 tenant.
2. Test the issue at other network environments, such as home network.
In addition, does “one default account” mean the origin administrator account of the Office 365 tenant, such as email@example.com?
I have been provided as a login for the service so far (firstname.lastname@example.org), I have not set up any additional accounts as i do not require any at the moment until i get this login problem sorted with the first account. I signed up to Office 365, it assigned me the above email address to use as a login for everything, I have been using that one login for the trial of all the services well apart from the Lync so far. I have also tried installing it on 3 PCs, 1 in Germany and the 2 in the UK, all on different networks. Sharepoint site works with the login, as does Outlook locally and on the OWA anywhere, only Lync is having trouble and won't get past the error message below at login.
Will do Brent,
Thanks for the help. I have received the PM and have started it, I will let
you guys know how it goes.
*edit* after running the clean-up and re-installing, sadly no progress.
Hi HCS Matt
I will wait for your response on the matter. if it doesn’t work let me know and i will ook further into it.
Sadly still the same error. Just tried to log in.
*Picture of the error* -
*off topic* I like the new SkyDrive App on the Desktop, would like a ‘right click - send to - view, veiw/edit, public' shortcut option from the desktop app to complete it for me, like the hold function on the WP7 that works very quickly to share or change permissions, Xobni does this well from Outlook for emails at least for now.
Thanks for the time and help. Any ideas on Lync ?
Have you tried to set manual configuration since the reinstall of Lync? If you have not try that to see if you can sign. If you have tried that since the reinstall and it is still not working let me know. Im looking deeper into the issue for you.
Are you still seeing this problem?
If so, are you using a custom domain at all in your Office 365 environment (Like you're own .com etc)
Also, does Lync work inside Outlook Web Access or do you see an error about the Contact list not being available?
When I first set up my free trial it took about 48 hours for Lync to work....
It has been some time since you have replied. Has Lync started working for you or were you able to find additional assistance on the web? If you are still having issues with Lync i am here amd happy to assist you further.
It has been 48 hours since my last responce and i was wondering if you had found the resolution on the web or if it finally started working. i look forward to
Continuing to help you.
It has been a few days since your last responce and i was wondering if everything is now working for you? If you need any further assistance i would be happy to continue to help.
I hope you were able to find what you needed to resolve your issue. if you need any assistance please feel free to contact us anytime.
Thanks Brent Coldewey
Tried again to log in just now, all working now.
I haven't done anything since my last clean up attempt, on a laptop i didn't perform the cleanup, it logged in first attempt after so many previous failed attempts.
Thanks for everyone’s help.
