iPhone and Office 365 - sent messages aren't delivered, aren't saved
Posted on 2014-02-05
Looking for advise and help on a issue affecting a few users in our organization. We are migrating to Office 365 and email in the cloud; a few of our migrated users have reported the following:
After weeks of the iPhone working properly with their 365 mailbox, they find that when they send messages using their 365 account on the iPhone, the message is not delivered to the recipient, is not in the Outbox or Drafts folder on the iPhone, and no Sent Item is kept. The message essentially just disappears.
The message appears to be sent and no error messages are displayed.
Shutting down and restarting the phone fixes the problem but we believe it will reoccur. This behavior did not occur with our on site Exchange 2010 servers.
Wondering if any other corporate Office 365 mail users were seeing this; additional information as follows:
- Affected users are using the native iOS Mail app for their 365 mail.
- Setup of the 365 mailbox on the affected iOS devices was done as follows:
Existing Mail Account is deleted; then -
New Mail Account is created with following settings:
Email address: email@example.com
Password: user's AD account password
Description: Company name
User name: user'sADname@ourcompany.com
