Email Profile

If your Outlook email client was still running after the migration was complete you will receive this message

When starting your email for the first time you will need to enter your username and password

SUCCESS

If everything works as expected this is all you will have to do.

ISSUE #1

It may appear that your email client is working as expect but if you start to receive intermittent errors (see two examples below). you will have to rebuild your email profile.

• You are able to send email but with subsequent emails you may receive an error "The operation failed"

• Trying to delete an email you may receive a message "The operation failed ..."
• 

SOLUTION

To resolve this issue you will need to rebuilt your Email Profile

• Open Control Panel
• Click User Accounts
• Click Mail
• Click Show Profiles
• Click to Highlight the email profile(s) you want to delete
• Click Remove
• Click OK

• To cleanup old data before rebuilding the email profile you need to delete any old OST files (Offline email files)
• Goto %userprofile%\AppData\Local\Microsoft\Outlook
• Delete all OST files

NOTE: everything in this folder can be deleted, but the OST file is the largest file so should be deleted.

• Run Outlook to re-setup the email account

ISSUE #2

If you have your email setup on more than one computer you may notice that only one instance will work.

Symptoms

1. After setting up email on the second computer your Outlook client on the first computer freezes.
2. You receive the following error message when starting Outlook.  This error references an .OST file which is the file used to keep your email offline.

SOLUTION

Only one email client can be set to offline mode.  This will only affect you if you have no access to the Internet (which is a rare instance but is important to note).

To resolve this issue you will need to turn off email caching on on of your Email Profiles

• Open Control Panel
• Click User Accounts
• Click Mail
• Click Show Profiles
• Click to Highlight the email profile(s) you want to update

• Click Properties
• Click Email Accounts...
• Double click your email address
• You will now see the following screen

• Uncheck Use Cached Exchange Mode
• Click Next
• Click Finish
• Click, Close, Close, Ok to exit the setup menus

NOTE: Email should now work on both your computers.

Setting up E-mail on your Smart Phone
