Thread: Desire stops syncing with Exchange

For two weeks this apps works fine, syncronising perfectly well with my MS outlook mail, contacts and calendar. 2 days ago I realised that outlook email has not been coming in through auto sync. When I (force) synchronise, I keep getting the message "Sync Protocol Error" for the mail. I can send emails but cannot receive. The calendar and contacts are synchronised ok. I can sync other folders but not Inbox.

After about a week it happened again. No outlook emails coming in. When force sync, "Sync Prorocol Error" came out. However I can send emails and I can sync "sent item" folder but not "inbox". Calendar and contacts are ok. SO I deleted the account and recreate it again (of course very tedious), then everything is back to normal.
Anyone experienced and found answers to this.

I too am having this issue. I have a Droid Incredible. The issue was occurring on 2.1. Unfortunately since my upgrade to 2.2 the issue still occurs at what appears a greater frequency. While contacts and calendar will continue to sync without issue, mail will no longer display new inbox items and displays the error "Sync protocol error" with the sync icon and an exclamation mark preceding the error. I can still send new mail, but cannot receive.

The only workaround I have found to work is to delete the mail account from my Incredible and re-add it which is tedious at best and only helps for a day or so before it occurs again.

I too will be switching off this phone as soon as possible because my business exchange mail is too important to me to have to continually deal with this headache. My plan is to wait this headache out until January when Verizon will hopefully have the iPhone. Hopefully HTC / Android comes up with a fix before then or my switch to Android will be doomed.

Sync problem with exchange here to! Agenda wont sync :-( Non of the solution above helps ...
Mail & contact works.

i went into my outlook account and moved all messages received since the sync error started into a different folder. I also cut down all of the receive settings on the phone to the lowest/lightest settings, e.g. headers only, download 1 day of mail... Additoinally, i deleted the most recent inbound mail off the phone.

rather than testing after each of those steps, i did them all at once, so one or more may be unnecessary, but after doing this, i'm getting mail again.
