Default Sync via OWA stopped working.

Please Login to Remove!

Hi all. I hope someone can help me out with this one.

I have two people who have their Blackberry sync to Exchange using the "OWA" method. This was working fine up until recently.

Now, all of a sudden, no e-mails are going to the BB at all.

Reviewing the IIS logs shows that there is nothing happening between the BB and Exchange after the initial authentication.

This is what I see now in the IIS logs:
Code:
PROPFIND /exchange/username - 80 - a.b.c.d browser-agent 302 0 0
POST /exchange - 80 - a.b.c.d browser-agent 302 0 0
GET /Exchange - 443 - a.b.c.d browser-agent browser-agent 401 2 2138074254
GET /exchweb/bin/auth/owalogon.asp url=https://server.domain.com/Exchange&reason=0 443 - a.b.c.d browser-agent 200 0 0
GET /exchange - 80 - a.b.c.d browser-agent 302 0 0
GET /Exchange/logon.asp - 443 - a.b.c.d browser-agent 401 2 2148074254
This matches exactly what I see for a "good" connection, except with a good connection, it does the owalogon.asp request again, followed by a POST to owaauth.dll, two PROPFINDs on the mailbox and then SEARCH on the Inbox.

I do not know why there would suddenly be a difference. No configuration changes has been made on the web server or exchange server. No patches has been applied to the server since 9/5/08 (according to dates on $NtUninstallKBxxxxx folders), and logfiles confirmed that the Blackberry sync worked after this date.

One of the Blackberries in question is a Pearl, I don't know what the other one is.

Any ideas where to look?

Did these users recently change their password?

No, no password change.

Your email server wasn't down for an extended period, either?

Have them log into their BIS setup and delete and re-enter the account.

Log into the BB webclient and ensure the e-mail accounts are still "validated".

No, the server hasn't been down for any extended time. It was rebooted on Sept. 5th for patches, but based on the IIS logs, the BBs were able to collect e-mail after that date.

Re-creating the account setup on the BB might be the way to go.

The OWA setups are not set up on the BB webclient, it's configured on the device itself. The redirection of a yahoo mailbox is still working for one of the two devices (there's no such setup on the other that I am aware of), so this part is actually working.

Update: Deleting and re-creating the account setup on the BB solved the issue.

Still odd that this would happen out of the blue...
