“Either there is no default mail client or the current mail client cannot fulfil the messaging request. Please run Microsoft Outlook and set it as the default mail client.”<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This is a trick problem, try below two solutions.<\/p>\n\n\n\n

Solution 1: Delete all versions of office and install the version that you need.<\/strong><\/p>\n\n\n\n

Looks like the problem was situation with (at least partially) installed 2 different MS Office’s. One was preinstalled by computer manufacturer Office 365 waiting for activation and another was installed by the user like Office 2016.<\/p>\n\n\n\n

Carefully uninstall both and then installed again only Office 2016. This problem should be gone.<\/p>\n\n\n\n

Solutions 2: Add persimmon to below reg key<\/strong><\/p>\n\n\n\n

1. Open registry by typing regedit in run.<\/p>\n\n\n\n

2. Search for the office productguid in HKEY_CLASSES_ROOT\\Installer\\Components\\<\/p>\n\n\n\n

3. Right Click the Sub Key that started with (for me) ‘F1291BD604B8604……’<\/p>\n\n\n\n

4. Select Permissions, Add ‘Everyone’ and give read only Access to that group.<\/p>\n\n\n\n

5, Navigate to <\/p>\n\n\n\n

32Bit Office<\/p>\n\n\n\n

LOCAL_MACHINE\\SOFTWARE\\Clients\\Mail<\/p>\n\n\n\n

64bit Office<\/p>\n\n\n\n

HKEY_LOCAL_MACHINE\\SOFTWARE\\WOW6432Node\\Clients\\Mail<\/p>\n\n\n\n

Check the spelling on the (Default) setting, it should say “Microsoft Outlook” to match the key present in Mail.  <\/p>\n\n\n\n

Some machines could spell it wrong like “Microsoft Outlok” for some reasons<\/p>\n\n\n\n

Solution 3: Check and rename below reg key<\/strong><\/p>\n\n\n\n

HKEY_LOCAL_MACHINE\\SOFTWARE\\WOW6432Node\\Clients\\Mail<\/p>\n\n\n\n

There was a key PreFirstRun with value:<\/p>\n\n\n\n

“Either there is no default mail client or the current mail client cannot fulfill the messaging request.  Please run Microsoft Outlook and set it as the default mail client.*Microsoft Office Outlook”<\/p>\n\n\n\n

Re-named key<\/p>\n\n\n\n
