My copy of OE became corrupted and I don't have time to learn how to do re-download it (if possible) or repair it. As I have the OEM Windows XP install disk, it may be repairable, not sure, but it doesn't appear in Add/Remove programs in Control Panel.
I found it simpler to change to Thunderbird, which works beautifully. After you change it to you default mail program in Internet Options, it will work seamlessly with browser functions such as "send file" or "send link". Also, the "make my pictures smaller" function, which reduces file sizes for easy mailing (lets you send 20 photos instead of 2 or 3) works with Thunderbird: select a group of image files, right click and select "send to e-mail recipient" A "make my photos smaller" dialogue box will appear: you may opt to send original sizes, or select from one of three smaller resolutions. Windows does the work for you and then loads the smaller files into an e-mail (Thunderbird, if you have changed default e-mail setting to Thunderbird).
I fixed my e-mail problem in fifteen minutes with the Thunderbird download. The normal default program for Thunderbird is IMAP, but you can easily change to POP3 when you configure your mail accounts. I had to enter the pop and smtp addresses, along with user name and password, but Thunderbird automatically detected the proper port settings.
My only gripe is the lack of a unified Inbox....I have an Inbox for each mail account (six of them....). There may be a way to create a single Inbox and change the default incoming mail location to a single Inbox, but I haven't found the time to try this yet.
