Email Client Setup Guides

Add your Global MCS mailbox using the instructions for your Outlook edition. Menu labels vary by release.

1. Classic Outlook for Windows: Open File → Add Account, enter your full email address, open Advanced options, choose manual setup, and select IMAP.
2. New Outlook for Windows: Open View → View settings → Accounts → Your accounts → Add Account. Enter your address and follow the prompts; use the IMAP/manual settings when requested. Do not look for the classic Advanced options screen here.
3. Enter the incoming and outgoing settings below. If using POP3 instead, use its separate incoming port.
4. Where shown, leave Require logon using Secure Password Authentication (SPA) unchecked. Use normal mailbox-password authentication over the encrypted connection. Enable outgoing SMTP authentication with the same credentials.
5. Complete the connection test and finish setup. For Outlook for Mac, use that edition's Add Account flow; Windows menu paths do not apply.

• Username: Your full email address; use your mailbox password.
• IMAP (recommended): webmail.globalmcs.net, port 993, SSL/TLS.
• POP3 (alternative): webmail.globalmcs.net, port 995, SSL/TLS.
• SMTP: webmail.globalmcs.net, port 465 with SSL/TLS, or port 587 with STARTTLS.
• SMTP authentication: Required, using the same full email address and mailbox password as incoming mail.

Use the server hostname supplied for your account. A custom name such as mail.yourdomain.com works only when its DNS and valid certificate are configured for that name. If a certificate warning appears, stop and contact support to correct the hostname or certificate. Do not bypass the warning or disable certificate validation. Enter your password only in your own mail application or verified control panel, never in a support chat.

Add the mailbox to Apple Mail on iPhone or iPad. Current versions use Settings → Apps → Mail → Mail Accounts → Add Account; older versions may place Mail directly under Settings.

1. Enter your email address and continue. For manual setup choose Add Other Account → Mail Account (older versions may show Other → Add Mail Account).
2. Enter your display name, full email address, mailbox password, and an account description.
3. If automatic setup cannot find the account, choose IMAP and enter the incoming and outgoing server details below. The outgoing username and password are required.
4. Continue verification, enable Mail, and save. In the account's advanced/server settings, confirm the selected secure ports.

• Username: Your full email address; use your mailbox password.
• IMAP (recommended): webmail.globalmcs.net, port 993, SSL/TLS.
• POP3 (alternative): webmail.globalmcs.net, port 995, SSL/TLS.
• SMTP: webmail.globalmcs.net, port 465 with SSL/TLS, or port 587 with STARTTLS.
• SMTP authentication: Required, using the same full email address and mailbox password as incoming mail.

1. Open the Mac Mail app and select Mail → Add Account.

3. Enter your display name, full email address, and mailbox password. When manual settings are requested, choose IMAP and enter the incoming and outgoing server information below.
4. Complete sign-in, select Mail, and finish. Under Mail → Settings → Accounts → Server Settings, review the connection settings if automatic setup does not work. Older releases call Settings Preferences.

The steps below are for the Gmail app on Android. Samsung Email has a different interface: use its Add account/manual setup flow and the same server settings.

1. In Gmail, tap your profile picture, then Add another account → Other.
2. Enter your full email address, tap Next, select Personal (IMAP), and enter your mailbox password. Some versions offer Manual setup.
3. Enter the incoming IMAP settings below and continue.
4. Enter the outgoing SMTP settings, with sign-in required and your full email address and mailbox password.
5. Finish setup and choose your synchronization, notification, and display-name preferences.

• Username: Your full email address; use your mailbox password.
• IMAP (recommended): webmail.globalmcs.net, port 993, SSL/TLS.
• POP3 (alternative): webmail.globalmcs.net, port 995, SSL/TLS.

Add your mailbox in Thunderbird on Windows, macOS, or Linux. Menu labels vary by release.

1. Open Account Settings and use Account Actions → Add Mail Account, or the welcome screen's existing-email-account option.
2. Enter your display name, full email address, and mailbox password. Saving the password on your own device is optional.
3. Choose Configure manually. Set IMAP and SMTP using the ports and security options below; use Normal password authentication and the full email address for both usernames.
4. Choose Re-test, then Done once the settings verify. Allow time for folders and messages to synchronize.

• Username: Your full email address; use your mailbox password.
• IMAP (recommended): webmail.globalmcs.net, port 993, SSL/TLS.
• POP3 (alternative): webmail.globalmcs.net, port 995, SSL/TLS.

For classic Outlook on Windows, first identify the data file under File → Account Settings → Account Settings → Data Files. Close Outlook and make an independent backup before repairs.

1. PST files: Locate SCANPST.EXE in your Office installation, commonly C:\Program Files\Microsoft Office\root\Office16\ or its Program Files (x86) equivalent. The location depends on installation.
2. Open SCANPST, browse to the affected .pst, and start the scan.
3. If errors are found, keep the backup option enabled and choose Repair. Restart Outlook and review recovered folders, including Lost and Found. Recovery is not guaranteed.

OST files: These are normally synchronized caches, not standalone PST archives. For Exchange, Outlook can recreate the OST from the server. Before any cache/profile recreation, confirm server copies exist and back up or export unsynchronized mail and local-only folders, contacts, and calendars. For an IMAP mailbox or uncertain data, ask support for the appropriate recovery procedure rather than deleting the OST. Do not use the PST repair steps indiscriminately for OST files or new Outlook.
