Windows mobile 6.1 & exchange activesync

That is, when you sync your exchange over-the-air, via GPRS / 3G whatever...

For some reason - a bug no doubt - wm6.1 wouldn't sync and gave me error 0x8503001C. It seems a lot of people have this, and there's a lot of google results which suggest all manner of crazy solutions. This seemed to happen only with either email or calendar chosen.

Mine? don't sync with the webmail address (of the exchange server), use the 'proper' address for it. This, unfortunately, requires you to setup a specific work connection (i.e. a private APN, not the normal internet connection), which causes other hiccups. Saying that, it does work with direct push, which webmail address didn't.

SD card slot with Dell D420 & XP SP2, and SDHC

Seems not to like it, and drivers from Dell are for SP1 or before.

Pop the SD card in, then goto device manager. It will show the card with a yellow question mark. So, uninstall it. Reboot, with the SD card in. Upon reboot, all will be well.

BUT, this only works with 'normal' SD cards; 4Gb or greater are SDHC spec. Google KB934428 and install that (reboot, and wait)

Oggsync, Exchange

Usual routine is this; sync pocket pc with exchange OTA, then use oggsync to sync this to google calendar. (Yes, I could use google pc sync software, but I can't install it - corporate pc nonsense..)

Just upgraded phone. BEFORE running 2 way oggsync on the new phone REMOVE the google calendar, else oggsync will create duplicates of everything.

So, new phone - sync with exchange - remove google calendar - sync with oggsync first time.
