Mike is wondering if he should do anything to protect himself while using these public hotspots though. Leo says this is an important question because he's on the same network with other people, so there are risks. Other people could see traffic sent to and from his computer, and could use hacker tools that are widely available to get that data. This is mostly an issue when accessing email, but since he uses gmail, it's encrypted and won't be a problem. If the sites he's on use 'secure http' (https), then he should be ok.
John's friend uses Outlook and when he moved, Outlook can't find his email server. Leo says that it's likely that Comcast altered settings that prevents him from seeing it. Outlook doesn't support the standard port 25 SMTP port. So he'll have to use the secure SSL ports. He can enable that in settings, and then he should select port 465 or 993. Comcast blocks port 25. Here's a technote on how to use his email client from Comcast.
Alan would like to delete all the emails at once on his iPhone. Leo says if that email is on an IMAP server, then the messages are on the server and not on his phone.
Martin got some threatening emails and they have disappeared. Is it possible to recall an email? Leo says only if both parties are using the same program like Microsoft Outlook. The program can then connect to the other and recall and delete it. But that's really the only way. Is there any way to get the emails back for evidence? Leo says that's a good question. Martin's ISP may have a copy on its servers and exchange servers need to be involved. But Leo says that the email may still be on Martin's computer. Check the trash folder, spam folder, Chances are, she still has it.
Kenny wants to know if there's any easy way to sync Microsoft Outlook with Apple Mail? Leo says that if the email is handled via IMAP, then all that email is on the server. So if it's on an IMAP server, both Apple Mail and Outlook will access it in the same place. It may not get everything, though. If it doesn't then he'll have to export all of his mail and import it into Apple Mail.
Frank is ready to finally get rid of AOL and wants to know what's a better alternative; especially for email. Leo likes Gmail because he can sync all of his devices thanks to the IMAP email protocol which keeps all email at the server level. Frank can just use the webmail version or he can use an email client like Outlook. Mozilla has one called Thunderbird.
Tom is having issues getting into his Microsoft email and when he tries to reset the password, it won't help. Leo says it could be that Tom's email has been hacked and the user has taken over the email account. Leo says Tom will have to call Microsoft and have them walk him through regaining access to his mailbox. This is why second factor authentication is vital.
Byron has a Windows Vista machine, but after the update on May 16th, Outlook stopped working. The upgrade is constantly "in progress." Leo says what he doesn't like about Outlook is that everything is stored in one huge ball of a PST file and when it gets too big, it gets corrupted.
Bryon need to reindex the file, and there's a repair tool for that. He should go to Run > ScanPST.exe, and find the Outlook.PST file. Select "repair". That should fix it. Leo also recommends backing up that file from time to time, that way if it does corrupt, he can merely replace it.
Larry has Yahoo mail and he gets a ton of spam. He can't really delete all of it at once, because sometimes email from friends gets in there. Leo says that if it's any consolation, everyone gets spam. Yahoo is just doing a poor job of filtering it. Leo says that we've lost the battle against spam, and some webmail providers filter it better than others. Google uses a technique called collaborative filtering, where users let them know if an email has slipped pass their filters and it adds to the list.
Chris' Network Solutions email account has thousands of emails and he's having trouble with them getting to his iPhone. He wants to clear them all without having to delete one at a time.
