Hi,
it seems I have the same issue as described with the first post. I use a Nokia Lumia 920. Synchronizing mail stopped working two weeks ago when I changed my user account password for the company's Exchange server (yes, I updated the password on the phone). We have some other WP8 users in the company but they don't have the issues. The difference to those other users is that none of them has the Nokia Lumia 920 (they have other phones, e.g. 620) and that they did
not set up the Microsoft Live Mail account when setting up the phone for the first time. I.e. they created the Live account but they did not set it up as mail account on the phone. I got the advise to set my phone back to factory defaults to get rid of the Microsoft Live mail account (as there is no other way to get rid of it, once set up... thanks for that). I don't want to do that, but I will try it soon if that is the only chance I got.
Mail synchronization seems to work when I am not logged into wlan. But not always. Manual synchronization (clicking the sync icon while viewing the mail folder) works usually when not logged into wlan. With wlan turned on the sync worked once or twice only directly after recreating the mail account.
I recreated the mail account several times. It did not help. I have another mail account (to a private Horde server) set up on the phone. I even deleted that account and tried recreating the company mail account. Did also not help... I was assured that the server certificate did not change since I got the phone. After creating the mail account, I am asked whether I want to accept the certificate, as it is self-signed (I confirmed this, of course). I even installed the company's root certificate on the phone (by sending it as an attachment in a mail to myself... seriously? wtf?). There seems to be no way to review installed certificates, so I cannot verify if there is really an issue with the cert (I don't think so).
The version of the Exchange server seems to be 14.3.123.3 (I have no experience with mail server configuration and no direct access to the server).
So I have three accounts on the phone:
- Microsoft Live (which I cannot delete)
- company (Exchange, with domain, that's the one not working)
- private (Horde, different domain, deleting this account did not help)
The company mail account did work without problems until two weeks ago, when I changed my password.
If you (I hope there is actually someone reading this who might be involved in Nokia Lumia phone development and/or Windows Phone 8 development) have any further questions feel free to ask. I will check this thread for a couple of days, maybe weeks.
Cheers
