Hi @MuhammedShehim-8313 ,
Did you change any Exchange related settings before this issue occured?

1..As a workaround, you could run the following command to setting the correct timezone and regional for all user mailboxes:

 Get-mailbox -ResultSize unlimited | Set-MailboxRegionalConfiguration -Timezone "<>"

Have you set up the Web Application Proxy for OWA?
2.Please run the following command to check the settings of the OWA virtual directory, especially whether the internal and external URLs are the same.

 Get-OWAVirtualdirectory | fl *auth*,*url*

3.If you set the WAP, please run the following command and see if the issue is resolved:

 Get-WebApplicationProxyApplication [app name] | SetWebApplicationProxyApplication -DisableTranslateUrlInRequestHeaders -DisableTranslateUrlInResponseHeaders

There is a similar case:Connection to the backend server failed. Error: (0x80072ef1). OWA with Claim through WAP and ADFS
