blackberry 8830 world edition not retaining email or phone call lists

I am not using BIS or BES.   I setup my corporate email to send to my blackberry , and it worked correctly up until last Friday.

Well you have to use something, how would your email get forwarded to your blackberry.  Did you not setup something with the carrier when you got the device? If you are forwarding to your device, you ran thru the email setup on the bb device correct?

The reason your messages and phone logs are disappearing is mostly likely related to the device running low on memory.  Skip what I said about bis or bes does not matter.

Once you check the memory do a hard reset by pushing alt cap del keys all together tha( should resolve temporarily

How do I check the memory?

If I do a hard reset, does that lose all of my presets that I've setup?  How about my address book information?

By the way - when I set it up I'm assuming that the email setup is going through Verizon's blackberry servers since I don't have a corporate BES at my company.

1) Checking memory = 2 places I would look, first look at the traditional scenario, go to Options > Status.  It will show free memory. The other is look at the database sizes for the different apps on the bb, go to Options>Status>Menu>Data Base Sizes for that.

2) Hard reset is just really a reboot, you will lose nothing.  Every once in a while it a good thing to do this to the blackberry anyway.

3) You got it on that one.  If you log onto the Verizon website and set up the BIS, which is free it will probably work better for you anyway then the forwarding mechanism. I would recommend it. At present do you have your blackberry address setup as a contact in your exchange environment? If so, you know this already, everytime you reply, you reply as the vzw blackberry.net account then your actually business email account, just another advantage of BIS.  As long as all you care about is the email, it is a good option and works well and has some little functions that make it easier to use.

BIS takes 10 minutes to set up.

OK - In Options -> Status I have
File Free - 0 bytes
File Total - 47841280 bytes

Sounds like I've filled up all my memory.

Now that my phone won't show those past emails, how can I access them to remove them and bring my free space back down again?

I don't see Option -> Status -> Menu on my phone.

When you say "hard reset", do you mean turning it off, then on again?  I've done that, but if this is an issue with too many files stored locally, then that won't fix it I would think.

Thanks for all your help, very nice to have someone walking me through all of this.

Thanks for your help; I'm going to back up my stuff first and then do the hard reset.

Glad to help and good luck.
