我有一个htc desire c，只有几周大。我还有一份新工作，并决定通过Exchange ActiveSync添加我的工作电子邮件帐户，但是一旦明白我放弃了我自己的手机的权利和功能（例如屏幕模式锁定）我决定删除它。< / p>
I have an HTC Desire C, just a couple of weeks old. I also have a new job and decided to add my work email account via Exchange activeSync, however once it became apparent that I was giving up rights and functionality (such as the screen pattern lock) for my own phone I decided to remove it.
I removed the administrator, which automatically removed the email account, however I am still unable to restore the screen pattern lock. I've restarted the handset a couple of times, no help.
I seem to have no options to view or delete and administrator accounts (presumably, and hopefully, because there are none now).
I've read the similar question posted here and the answers but they don't help me sadly. Any ideas?
Converting my comment into an answer, as it proofed according to its follow-ups:
In a thread at XDA, a user states:
I had the same problem when i tried to setup an exchange email account and installed a certificate. Fixed it by deleting all certificates. Settings>Security>Clear credintials
So I'd suggest you just do that.
For additional information, also take a look at this thread at Android-Forums, which deals with the same problem you mention as example in your question ("screen pattern lock" -- here: disable lock screen).
You'll need to follow some simple steps to remove Exchange Active Sync password from Android.
Mobile restarts automatically and you get happy.
I went to Security - Device Maintenance and deleted the corporate email setting
Go to settings, find themail "Accounts" section and click on the "Google" sub section. Your Google accounts should be displayed. Click on the account you don't want and the. In the bottom right corner of your phone screen there should be an option to " Remove Account". Click this and youp problem should be solved ^-^
