We have a strange situation where one user is unable to send email to a specific email address and cannot add it as a contact either.<br />
<br />
When entering the address in the To field and click send, the address disappears and outlook say something went wrong with sending. &nbsp;Under contacts, if we try adding the email address to a new contact, after adding it to the email field and clicking on another field, the address gets removed and the email field is blank again.<br />
<br />
I checked junks settings and the address is not on the block list. &nbsp;We also ran repair on office and rebooted. &nbsp;We also cleared the autocomplete cache as it is now disabled in GPO. &nbsp;Also tried starting outlook in safe mode (all addins disabled).<br />
<br />
The system is Windows 7 x64 and office 2013 standard x86. &nbsp;It is connected to exchange 2013 but other users can send to this email address without issue so it is a mystery setting on this particular user's computer. &nbsp;The user is able to send to other addresses and add other contacts without issue. &nbsp;It is just this specific email address that is somehow blocked.<br />
<br />
Any ideas?

Cannot send email to specific address or add it to contacts

Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note-taker, journal, and web browser.

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

A contact manager in its most basic form is a software program that enables users to easily store and find contact information, such as names, addresses and telephone numbers. Sophisticated contact managers provide calendar sharing features and allow several people in a company to access the same database. Some contact management systems have evolved into customer relationship management (CRM) systems to analyze and plan for an organization’s interaction with current and future customers.

Contact Management

An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.
