Hello folks, I'm having problems for the last few days with a gmail account, which is used like many other accounts from the same domain www.institutoxxxx.com through an e-mail client, thunderbird-in this case, this has to run normal and correctly, a few days here is began to generate a little strange at the time of receiving emails or send slow slightly delayed the procedure of copying to sent folder as is may show images attached, constantly received messages: sending connection information, looking for folders, and when trying to open an email with attachment: loading message; These messages take a few minutes to disappear and looks that she is synchronizing but does so very slowly. The settings in Thunderbird I have done it several times following the signs in the support page https:support.mozilla.orgeskbthunderbird-y-gmail try to configure account using the outlook client and experience the same slowness when trying to synchronize the account. The most curious case is that if I try to open the account through the web can do, and the sending and receiving of messages is normal, agile and efficient. The account has about 12GB of space, but storage is unlimited. Is formatting the computer to rule out problems of virus Were tested by configuring thunderbird client accounts without installing any antivirus software to rule out blockades by these applications You disable windows firewall Change computer and you configure the account in thunderbird with the same results, it should be remembered that other accounts that use the same domain and the same client (THUNDERBIRD) does not present any problems. Use the account through the WEB is a momentary solution by political generals, all communications through e-mail accounts must be tagged with the institutional signature, using the html format.
